In manufacturing, machining is a process employed to create products, parts, and designs by removing material from a workpiece. This method incorporates various types of processes that utilize power-driven tools for chipping, cutting, and grinding to modify a workpiece to meet precise specifications. The machining process is instrumental in producing items such as metal fasteners, costume jewelry, toys, and hand tools. Occasionally, a completed part might require refinements to satisfy quality benchmarks or specific manufacturing criteria. In such situations, machining is used to achieve the desired finish and appearance.
Machining extends beyond metals, offering versatility across numerous materials. For example, molding is conventionally used to shape plastic and rubber items. Often, post-molding enhancements are necessary, implemented through machining techniques such as drilling holes, material removal, or shape refinement. Even pliable materials like paper can be machined to reach distinct patterns or forms.
A wide variety of machining tools are fundamental to modern manufacturing and precision engineering, used to shape, deform, and mold metal and other materials to produce specific geometric forms and complex parts. The machining process involves tightly securing the workpiece, typically with a vise or chuck or automated clamping systems on CNC machines, ensuring rigidity and safety as cutting, shaping, and finishing operations take place. Whereas pre-industrial era machining depended on painstaking handwork, today’s workshops and manufacturing facilities harness advanced computerized numerical control (CNC) systems. These systems translate digital designs and machining programs into precise, repeatable tool paths, enabling mass production and extremely tight machining tolerances that are crucial in automotive, aerospace, medical, and electronics industries.
To execute the diverse industrial operations required to transform raw materials into finished components, a broad range of machining tools is selected with care to optimize factors such as material type, required tolerances, surface finish, production efficiency, and tool longevity. High-performance machining relies on the optimal pairing of tools and processes to achieve the desired result and maximize productivity.
Below, you'll find a comprehensive list of some common—and essential—machining tools along with their specific applications and characteristics, helping you navigate your options for industrial machining, precision manufacturing, or custom CNC machining?
Machining drill bits are among the most frequently used cutting tools in manufacturing and are vital for creating holes used for fasteners, dowels, and internal channels. Drill bits come in various types, including center, twist, and ejector, each tailored to a distinct industrial use case. Center drill bits excel at producing precise pilot holes that help initiate deeper drilling or tapping operations. Twist drill bits, with their spiral flutes, deliver sharp, accurate hole making, and their design efficiently channels chips away from the workpiece—although these bits require regular sharpening to maintain best results.
Insert drill bits are a cost-effective choice designed for quick alignment, but often leave burrs, necessitating additional processes such as reaming or deburring for a premium surface finish. Unlike insert bits, twist drills minimize burr formation. Tools like step and core drill bits are frequently used for enlarging existing holes or cutting through layered materials, making them ideal for fabrication, assembly production, and even sheet metal work.
Drilling is a core metalworking process and constitutes roughly 75% of holemaking operations in modern machine shops. Advanced drilling setups may use drill jigs, high-precision servo or hydraulic feeds, and coolant systems to boost hole accuracy, tool life, and to enable high-speed, automated CNC drilling across a range of alloys, plastics, and composites.
Milling is a subtractive manufacturing process that produces three-dimensional shapes and components using a rotating, multi-edge cutting tool called a mill. In CNC milling, the milling tool’s movements are controlled on several axes to achieve complex contours, pockets, slots, grooves, and surface features. CNC milling offers outstanding versatility, making it indispensable in the production of precision components, mold and die manufacturing, and rapid prototyping.
Key milling tools include end mills, which differ from traditional drill bits by incorporating multiple flutes on the sides and tips, allowing for advanced contouring and plunge cutting. Roughing end mills remove larger volumes of material, while finishing end mills achieve smooth, final surface finishes with minimal tool marks. Specialty milling cutters include face mills for high-speed surface finishing, slab mills for heavy-duty cutting, thread mills for precision threadmaking, and hollow mills for specialized forms.
Factors such as cutter geometry, flute count, tool material (e.g., coated carbide, HSS, or PCD), and cutting parameters (feed rate, speed, depth) are all optimized for the machining application to maximize tool life and part quality. Modern milling machines, whether vertical or horizontal machining centers, offer high rigidity, precision spindles, and advanced coolant/lubrication systems to achieve high surface quality and consistency.
Boring tools are precision cylindrical tools capable of rotating on multiple axes, allowing machinists to enlarge and achieve exact tolerances on pre-drilled holes. Common in automotive and aerospace parts production, CNC boring heads employ 3, 4, or 5 axes, enabling the creation of highly accurate, intricate internal geometries that drilling alone cannot achieve. Boring bars and cartridges are engineered for optimal rigidity and minimal deflection, ensuring superior surface finishes and tight roundness tolerances.
Boring is distinct from simple drilling by its higher accuracy, ability to correct misaligned pilot holes, and to create large-diameter or deeply bored channels. Fine boring achieves micrometer-level precision, critical for engine components, hydraulic cylinders, and precision housings. Automated boring can be programmed in CNC centers, reducing set-up time and eliminating human error from manual adjustments.
Boring can be performed horizontally, vertically, or at custom angles—making it highly versatile for industries that require close tolerances and perfectly aligned bores.
Grinding, also known as abrasive machining, utilizes abrasive wheels for ultra-precise material removal, fine surface finishing, and achieving tight tolerances far beyond conventional cutting tools. This finishing process routinely follows rough machining to produce perfectly flat, smooth, or specific texture surfaces critical for high-performance or aesthetically sensitive applications such as injection molds, bearing seats, medical implants, and precision optical components.
Grinding tools are categorized by their function: surface grinders (for achieving mirror-flat finishes), cylindrical and centerless grinders (for round rods, tubes, and shafts), internal (ID) grinders (for in-bore finishing), and specialty tools (e.g., creep-feed or tool and cutter grinders for specialty shapes). Grinding wheels are manufactured in a range of hardness, grit size, and bonding agents, tailored for metals, ceramics, or composites to maximize material removal rates (MRR) while minimizing thermal distortion.
Automated CNC grinding machines use programmable feeds, coolant delivery, and digital dressing tools to extend wheel life and ensure repeatability across production cycles. Continued advances in diamond and CBN (cubic boron nitride) abrasives have transformed precision grinding, making it the go-to solution for the world’s highest technology manufacturing.
Turning tools are essential single-point cutters used in lathes for shaping, facing, threading, or grooving cylindrical workpieces. This subtractive process is foundational to manufacturing operations for components such as shafts, bushings, and custom precision pins. Turning can be divided into rough and fine turning, each with specifically designed tool geometry to optimize chip removal or achieve high-quality smooth surfaces. Modern carbide or coated turning inserts, available in round, diamond, square, or octagonal shapes, improve tool wear-resistance and impact resistance for extended production runs.
During the CNC turning process, the workpiece rotates at high speeds while the cutting tool, controlled via computer programming, remains stationary or precisely moves along set axes. Different insert coatings and materials—such as TiAlN, TiCN, or uncoated carbide—are chosen based on the workpiece material (aluminum, steel, titanium, plastics) and the required finish. Computer-aided manufacturing (CAM) software enables incredible flexibility in generating custom threaded profiles, tapers, or internal and external grooves.
Key considerations for effective turning include spindle speed, feed rate, depth of cut, chip control, and the correct pairing of cutting tool and material type. Optimizing these variables boosts surface quality, minimizes tool wear, and can enhance cycle time, ultimately reducing production costs.
Machining cutting tools span a vast array of types, carefully chosen for the specific machine, application, material, and required precision. Most industrial shops utilize lathes, routers, CNC mills, plasma cutters, electrical discharge machines (EDM), and laser cutters for distinct applications from rapid prototyping to batch manufacturing.
The correct selection of cutting tools and tool holders is crucial—they directly impact dimensional accuracy, surface finish, setup times, and machine efficiency. Misaligned or inferior tools can increase downtime, reduce part quality, and escalate overall manufacturing costs. Advances in tool material technology—such as the use of polycrystalline diamond (PCD), ceramic, or cermet tooling—offer vastly improved tool life and cutting speeds when machining aerospace alloys and composites.
When evaluating costs, consider overall tool longevity, resharpening requirements, and compatibility with high-performance CNC or automated production systems. Solid carbide, indexable inserts, and custom tool solutions are often indispensable for high-volume manufacturing and specialty applications requiring non-standard geometries. Tools with more flutes and complex coatings perform best on hardened materials or for high-speed applications, while multi-purpose tools are ideal for general-purpose manufacturing and prototyping environments.
Sawing remains one of the fastest and most versatile machining processes, enabling quick separation or sizing of a workpiece during both initial blanking and secondary processing stages. This method is used on metals, plastics, composites, and other substrates, making it invaluable across metal fabrication, woodworking, and plastics machining industries. CNC sawing machines offer programmable speed, feed, and angle adjustments for efficient batch processing and non-standard shapes.
Continuous and reciprocating sawing both allow for efficient material cutting. Automated band saws, circular saws, abrasive cutoff saws, and friction saws support various material types with a range of blade options for high strength-to-weight ratio cutting, complex shapes, or minimal kerf loss. Sawing complements CNC milling and turning by rapidly creating blanks tailored for further precision machining, while plasma or waterjet cutting may be incorporated for intricate contours in advanced manufacturing workflows.
Broaching is an efficient material removal process used to create complex shapes, internal keyways, splines, and profiles in a single pass. Broaches are specialty tools with progressively taller teeth, ensuring a smooth and continuous material removal process for applications such as gear cutting, firearms manufacturing, and custom internal profiles. CNC broaching machines employ both pull and push broaching configurations, vertical or horizontal, depending on workpiece size and application.
Modern broaches are constructed from high-speed steel or carbide to withstand demanding production environments. Broaching is prized for its precision, repeatability, and speed, offering unmatched accuracy for high-volume production runs requiring intricate internal geometries. The right broaching machine and tool can dramatically increase efficiency, reducing both cycle time and post-processing needs.
Planing is still valued for shaping and smoothing large or long workpieces, especially when other CNC or grinding options are impractical for heavy-duty structural elements. In modern plants, large-scale planers deliver high-precision material removal, easily flattening, squaring, or surfacing large castings, plates, or frames. Automated planer machines offer multiple heads, CNC control, and precise feed adjustments, improving both speed and finish consistency for demanding applications such as heavy machinery fabrication and rail infrastructure.
Critical setup variables—including traverse rate, cut depth, and tool sharpness—must be calibrated for each application to achieve the right dimensional specifications, surface integrity, and overall productivity required for large-scale industrial projects.
Chemical machining (CM), also known as chemical milling or photochemical machining, is a subtractive process that removes metal or material using carefully selected acidic or alkaline chemicals. This method is ideal for components requiring fine, intricate geometries with no risk of mechanical distortion or tool-induced stress—common in aerospace, electronics, and medical device manufacturing. Chemical machining shines in the production of thin, lightweight, and intricately shaped parts that are difficult or impossible to machine conventionally.
Modern CM employs photoresist maskants, automated chemical baths, etch-rate controls, and rigorous cleaning processes to achieve highly uniform material removal, precise tolerances, and smooth finishes while preserving the original material properties. Continuous process improvements and advances in automation have further increased CM’s relevance for high-mix, high-precision components outside the reach of traditional machining.
Electrochemical machining (ECM) is a state-of-the-art machining method perfect for difficult-to-machine, hardened, or delicate metals—such as superalloys, stainless steel, and titanium. ECM applies a direct current and electrolyte solution, dissolving metallic ions in a controlled pattern to replicate the shape of the cathode onto the workpiece. As a non-contact, non-thermal process, ECM is widely used for burr-free finishes in applications requiring exceptional surface integrity, such as aerospace components, medical implants, tool and die finishing, and fuel-injector nozzles.
Key features include high repeatability, zero mechanical tool wear, no heat-affected zones (HAZ), and the ability to machine complex and miniature features with extremely tight tolerances. Advanced ECM systems use pulsed power and adaptive controls to further optimize material removal rates and precision on complex 3D forms.
Abrasive jet machining (AJM), a non-traditional machining process, uses high-velocity abrasive particles propelled by a jet of air or inert gas to cut, shape, or deburr fragile, heat-sensitive, or complex parts. This is especially effective for brittle non-metals, thin sheets, and precision electronics or glass components where conventional machining would cause chipping, cracking, or distortion. AJM is frequently used for micromachining, drilling intricate holes, or scribing delicate features—processes that benefit from minimal mechanical or thermal impact.
Ultrasonic machining (USM) represents a precision, non-thermal, non-chemical method of erosion, utilizing high-frequency vibrations and fine abrasives to remove material from hard, brittle, or delicate substrates. Industries such as medical device manufacturing, watchmaking, and optics rely on USM for extremely tight tolerances, intricate shapes, and damage-free machining of ceramics, glass, sapphire, or advanced composites. Built-in automation and advanced vibration controls further improve consistency and minimize downtime in batch or continuous production settings.
Electronic beam machining (EBM), or electron beam machining, is a cutting-edge technology that leverages concentrated bursts of electrons to machine extremely small features in conductive materials. EBM provides unparalleled precision for drilling micro-holes, engraving, and contouring in applications such as aerospace hydraulics, medical instruments, fine electronics, and microfabrication. With its capability for high aspect ratio features and minimal thermal distortion, EBM continues to unlock innovative designs and manufacturing possibilities.
The types of machining covered here are just a selection of modern methods used in today’s advanced manufacturing landscape. The ongoing evolution of custom and specialty machining tools underscores the industry's commitment to high-precision solutions for future-focused, innovative designs.
Mechanical methods of machining have been used for many years. Through innovation and technological advances, other processes have developed to remove layers without the need for grinding, boring, or mechanical tools. Some of these techniques are referred to as burning where the workpiece is heated and melted to achieve a shape or design. The most common types are laser, oxy-fuel, and plasma.
A laser beam, of high energy, contacts the workpiece creating thermal energy. The heat created melts, burns, and vaporizes the surface of the workpiece to shape it into a design. There are two types of lasers � gas and solid state. With a gas laser, gases are used to generate heat, which are He-Ne, argon, and Co2. Solid state lasers have different forms, which include YAG (yttrium aluminum garnet), Nd:YAG ( neodymium-doped yttrium aluminum garnet), and ruby. The laser cutting process can shape steel or etch patterns. Its benefits include high-quality surface finishes and cutting precision. Laser machining produces accurately placed cuts of high precision and has the ability to cut or shape any type of material.
Oxy-fuel cutting, also known as gas cutting, is mostly used to cut thick steel plates. The heat source for oxy-fuel cutting is produced by combining oxygen with some type of fuel such as acetylene, gasoline, hydrogen, or propane. The oxy-fuel torch heats the workpiece to kindling temperature, around 960° C. Once the proper temperature is achieved, pure oxygen is directed through a nozzle onto the heated cut. The oxygen changes the heated and unprotected steel into an oxidized liquid by an exothermic reaction. The created slag is blown out of the heated cavity. The process can cut deeper angles up to 70o and is more economical than the other burning methods.
Plasma cutting is an efficient and cost-effective technique used to cut steel. This process utilizes a plasma torch to create a plasma arc for the cutting operation.
The torch fires an electrical arc that transforms an inert, ionized gas, or plasma, which reaches an extremely elevated temperature. The heat from the torch is applied to the workpiece at high speed to melt away unwanted material. Metals machined in this way are electrically charged since an electrical current flows between the electrode of the torch and the workpiece. Plasma cutting can cut thin or thick materials. Handheld torches can cut materials of up to 38 mm thick while CNC devices can cut steel sheets of up to 150 mm thick.
Unlike traditional cutting methods that use heat to melt away excess material, non-traditional techniques rely on erosion to achieve the desired results. Methods such as waterjet cutting and electric discharge machining do not require physical tools to remove material. Instead, they utilize the power of abrasive-laden water jets and electrical discharges to cut through the workpiece.
Waterjet cutting is a versatile fabrication process that uses water under high pressure, mixed with an abrasive, to cut materials into custom shapes and designs. Water is pressurized using an intensifier or direct drive pump, which is capable of producing significant fluid pressure. As the water enters the cutting head, the water goes into an opening containing a hard jewel such as a diamond, sapphire, or ruby. The velocity of the water increases at the opening, which can reach 2500 mph. Abrasive powder is added to the water stream to cause erosion. Waterjet cutting is typically used on materials that can suffer damage or deformation from heat processes.
The EDM process is known as spark machining, spark eroding, die sinking, wire burning or wire erosion. Material is removed from a workpiece through the use of thermal energy without the use of grinding, drilling, cutting, pressure or force. Conductive materials are shaped and cut using an electrode that creates an electrical discharge between the workpiece and an electrode that melts and vaporizes material.
The EDM process excels at creating intricate shapes in hard materials. In this technique, both the workpiece and electrode are immersed in a dielectric fluid. Electrical current flows through the electrode, forming plasma zones that melt away material from the workpiece, resulting in a cavity that mirrors the electrode's shape.
Electrodes for EDM are crafted from various conductive materials, which influence the precision and form of the cutting. Commonly used metals for electrodes include copper, brass, graphite, molybdenum, silver tungsten, and tellurium copper, chosen for their conductivity and resistance to erosion.
There are three main types of EDM: die sinking, wire, and hole drilling. Die sinking, also known as ram or cavity EDM, is used to create parts with detailed cavities and sharp edges. Wire EDM, or wire erosion, produces precise extrusion dies and follows a similar method to die sinking. Hole drilling EDM is specialized for creating deep, fine holes and achieves this without leaving burrs.
Computer numerical control (CNC) machining emerged as a technological advancement in the 1950s, originally developed for manufacturing helicopter rotors. In the late 1950s, a project aimed at creating computer-aided design (CAD) software led to the development of AutoCAD. The integration of AutoCAD with CNC technology has significantly enhanced machining processes, enabling the production of parts at reduced costs with increased precision.
CNC has been applied to a broad range of manufacturing, production, and processing equipment. Software and programming, using the G-code computer language, develop commands and instructions to guide a machine through the shaping of a workpiece. The implementation of CNC has led to a decrease in losses due to human error and a significant drop in the amount of waste. Once a CNC machine is coded, it needs minimal maintenance or downtime and completes production at a faster rate.
Speed and lowered labor costs have made CNC a highly cost efficient method for producing high volume production runs. Down times for mishandled materials, insufficient supplies, or other production errors are eliminated. Every product and part is precision produced in accordance with exacting design specifications. Producers using CNC have the added benefit of more control of the total production process.
Precision machining is employed to produce components with minimal errors and tight tolerances, ensuring a high-quality finish. Techniques such as milling, turning, and electrical discharge are commonly used in this process, which requires meticulous attention to the design specifications.
This method is selected for its capability to meet exact dimensions specified in the design. Parts with stringent requirements for precision machining are subject to very tight tolerances, typically ranging from 0.0005 to 0.2, depending on the material and initial dimensions. Deviations beyond these tolerances can render the parts unusable.
The advent of CNC machining has greatly enhanced precision machining by improving tolerance levels and surface finishes. CNC technology allows designs to be transferred directly from computer models to the machine, which is programmed to execute every detail. The quality of the finished product can vary based on the CNC machine's capabilities.
Surface finish is a crucial aspect of precision machining, characterized by factors such as texture, roughness, and waviness. Each of these is quantified using mathematical formulas to assess the finish quality. Equipment manufacturers provide specifications detailing the achievable finish quality of their machines.
Precision machining is essential in industries like aerospace and medical manufacturing, where components must meet exacting standards for performance and safety, such as those used in spacecraft and specialized medical devices.
The 5-axis machining process extends the capabilities of traditional X, Y, and Z axes by adding two additional axes, A and B. This enhancement allows for shaping a workpiece on five sides in a single setup, eliminating the need for extra turning or additional setups. With a 5-axis machine, cycle times are faster, waste is reduced, spindle uptime increases, and operation becomes easier without requiring highly specialized training.
While a 3-axis CNC machine moves the part sideways on the X axis, vertically on the Y axis, and back and forth on the Z axis, the 5-axis machine introduces the A and B axes. The A axis tilts the worktable, and the B axis rotates it. The swivel-rotate style of 5-axis machines rotates the spindle, which is ideal for handling heavier parts, whereas the trunnion style features a moving table, making it suitable for high-volume production.
The advantages of 5-axis CNC machining include:
5-axis CNC machining often makes the seemingly impossible achievable by allowing a machine to complete all necessary cuts for a part in a single cycle. This capability streamlines operations such as milling, boring, tapping, threading, and grinding into a one-step process, enabling the creation of complex and intricate parts. Whether for single parts or high-volume orders, a 5-axis CNC machining system can handle both efficiently.
Machined parts are created through machining, a process that was once labor-intensive but has been revolutionized by CNC technology. Modern CNC machines are programmed to perform a variety of functions, delivering exceptionally accurate and precise cuts to produce high-quality parts. Unlike cast or forged parts, machined components are made with superior precision and accuracy.
Unlike forging and casting, machining allows for the easy production of prototypes, which can be examined and modified to meet specific application requirements. The CNC process begins with creating a CAD rendering, which is then downloaded into a CNC machine to quickly produce a prototype. This feature helps prevent losses during mass production.
Machined parts can be manufactured from a diverse range of materials, including steel, aluminum, brass, copper, titanium, stainless steel, and various plastics. The choice of material depends on the part’s intended use and the material’s mechanical properties, durability, strength, and versatility. Metals are commonly used for parts in industries such as automotive, aerospace, and construction, while plastics are often used in electronic devices, medical equipment, household products, and automotive applications.
While metals and plastics are the most commonly used materials for producing machined parts, machining is also effective for forming and shaping composite materials and ceramics. These materials offer unique characteristics that can meet specific application demands. Composite materials, such as epoxy resin, fiberglass, and Kevlar, are valued for their high strength-to-weight ratio, stiffness, and corrosion resistance. Ceramics, on the other hand, are known for their hardness, brittleness, thermal stability, and chemical resistance. Like composites, ceramics are recognized for their high strength, wear resistance, and non-conductivity.
The widespread adoption of machined parts is largely due to the numerous benefits they offer that are unmatched by other manufacturing methods. Machining eliminates the need for molds, dies, or other processing tools, reducing costs compared to casting and molding. It allows for production runs ranging from single, complex parts to large quantities, and also accommodates adjustments for special orders without affecting the original production requirements.
Unlike molding and die processes that require a minimum order quantity due to the creation of molds or dies, machining does not impose such requirements. Machining utilizes a blank placed into a CNC machine, which performs all necessary operations to shape the part. This capability enables small businesses to undertake extensive production runs without needing to alter tooling or develop specialized equipment.
Prototyping is a notable advantage of machining, allowing multiple iterations at low cost. Clients provide a CAD rendering to a machining engineer who then creates a prototype. If needed, adjustments can be made to the CAD design, leading to the production of additional prototypes. This iterative process is significantly less costly compared to altering molds or casting new dies.
Machining enables the creation of parts with any shape, size, or dimension, regardless of wall thickness or tapering. It allows for the production of parts that are either robust and durable or intricate and detailed. While there are some limitations regarding internal sections and channel depth, machining offers significant design flexibility for engineers.
This aspect of machining contributes significantly to its popularity. CNC machining allows for achieving extremely tight tolerances, as the part's parameters are fed into the machine, which executes each operation with high precision. Typical CNC machining tolerances are ±0.005 inch (0.127 mm), though it is possible to achieve even tighter tolerances of ±0.001 inch (0.0254 mm), comparable to the width of a human hair.
Such precision in adhering to design parameters ensures the production of parts with exceptional accuracy, making them a perfect fit for their intended applications.
The efficiency of CNC machining allows for rapid production without additional preparation or tool development. The process is driven by technology and computer inputs, allowing quick adjustments to accommodate urgent requests. Production can be shifted between large and small jobs without compromising quality, making it possible to fulfill a part request within a single day if needed.
In die and molding processes, tools must be shaped and formed before production begins. The part’s dynamics are carefully reviewed to ensure the die meets all requirements. Once a die or mold is created, making changes or corrections is not feasible. Conversely, machining allows for flexibility. A prototype is typically created and tested before full production to confirm it meets design specifications.
Once the prototype is approved, CAD data is transferred to the CNC machine to start production. During production, adjustments can be made or the design can be completely revised with minimal cost. This flexibility in machining enables modifications and updates at any production stage, leading to cost and waste savings.
Machined parts are made from a solid blank, preserving the material's original grain structure and strength. This inherent strength is crucial, as many machined components play critical roles in various applications and processes, ensuring reliability and durability in their final form.
Unlike molding and casting, machining does not involve the creation of flash, sprues, or flow lines, which require labor-intensive removal. Instead, machining processes such as bending, crimping, cutting, and drilling are directly performed on the blank, leaving the part ready for use or shipping once machining is complete.
Custom machined parts are created for various reasons, including the unavailability of parts, specific requirements, unique designs, or urgent needs. Previously, these parts were made using manual methods like lathes, mills, or stamping machines. However, with CNC machining, producing custom parts has become much more efficient and straightforward.
CNC machining can produce unique and non-existent parts with distinctive designs, structures, and functions. Custom parts range from simple gears to complex machine components. A CAD rendering of the part is converted into CNC code, allowing the machine to manufacture the part precisely.
Custom machining encompasses a range of processes, with 5-axis CNC machining being particularly prevalent due to its adaptability and flexibility. The process begins with prototype creation to assess the concept's feasibility. CNC machining simplifies this phase, as any digital format can be used to guide the machine.
Custom machined parts are based on client designs integral to innovative concepts. Often, presenting a custom part marks the culmination of a design process that has undergone rigorous testing and review. Manufacturers chosen for such specialized tasks are experienced CNC machinists with top-notch skills and expertise.
Some machined parts require additional finishing processes to meet design specifications. These treatments alter the part’s surface texture, improve appearance, or add designs. Finishing can be functional, aesthetic, or both, and aims to meet the detailed requirements of the design.
Blasting is an aggressive technique used to achieve specific surface textures by propelling abrasive materials like beads, sand, or gravel at the part. This method must be carefully controlled to avoid damaging the part, making it suitable for larger components that can endure the process.
Anodizing is an electrochemical process that enhances a part’s appearance and durability by adding an oxide layer. This layer provides corrosion resistance and extends the part’s lifespan. Anodizing can be tailored to meet the needs of different parts, with types including chromic acid, sulfuric acid, and hardcoat options.
Powder coating involves applying powdered paint to a part and then baking it to create a durable bond. This process results in a resistant finish that is wear and corrosion-resistant, offering a strong and long-lasting coating.
Several companies across the United States produce programmable CNC machines, each offering innovative solutions and excellent customer service. Their advanced technologies enhance the capabilities of CNC machines, catering to various manufacturing needs.
