Chapter 2: What are the approaches to metal finishing and polishing?

Different methods are employed to achieve metal finishing. These methods are outlined below.

Metal Polishing

Metal polishing is a process that smooths surfaces using abrasive materials. This technique removes imperfections from metal surfaces, resulting in a shiny, reflective finish with an improved appearance. Often, metal polishing is combined with buffing, which is gentler on the metal. Beyond its aesthetic benefits, metal polishing also helps to eliminate oxidation beneath the surface, thus preventing corrosion and extending the metal's lifespan.

Metal Polishing Process

Various abrasives can be used in the metal finishing process, with the choice of abrasive depending on the material being polished. When dealing with unfinished materials, several stages must be followed. Initially, a coarser abrasive is employed to eliminate imperfections from the surface. In the following stages, progressively finer abrasives are utilized to refine and enhance the finish of the material.

A mirror-like finish can be achieved by incorporating buffing and polishing compounds into the polishing wheels. Generally, polishing is applied as is, although lubricants such as kerosene or wax can be used in some cases. Die grinders, stationary polishers, or specialized equipment can be used to give a brighter shine during buffing.

For softer metals like brass, a very fine grit that is copper-plated can be employed to achieve a smooth surface. Buffing is performed using an airflow mop. Different tools, such as hammers, wrenches, screwdrivers, and chisels, each require specific polishing techniques due to their distinct characteristics. Initially, these tools are roughed out using a grinding wheel, followed by dry polishing materials to complete the process. In cases where additional polishing is necessary, grease may be applied.

Polishing enhances surface quality by reducing friction and wear, contributing to better performance and longevity of the tools.

Abrasives Used in Polishing

Various abrasives are selected based on the metal's strength during the polishing stage.

Metals with lower tensile strength, like copper, brass, and aluminum, typically require gray silicon carbide abrasives. These abrasives are also suitable for use on cemented and gray iron carbide.

For metals with higher tensile strength, such as carbon and alloy steel, non-ferrous metals, and iron alloys, abrasives like white and gray aluminum oxide are preferred. Green chromium oxide abrasives are specifically used for ferrous metals, including steel.

Materials like leather and canvas are commonly used in polishing. Other options include felt, plastic, wool, and rubber. Buffing wheels or mops often use cotton or wool cloth.

Applications of Polishing

In manufacturing, polishing is essential for items like kitchenware, cookware, automotive components, and architectural metals, ensuring they are market-ready. Polishing is also used to refurbish or mend metal parts when needed.

Buffing and polishing contribute to workplace safety as well. For instance, polishing can help prevent corrosion in specialized plumbing systems. In the pharmaceutical and dairy industries, polishing can eliminate mold and bacteria in pipes, reducing corrosion and improving product safety.

Metal Smoothing

Mass finishing can produce exceptionally flat surfaces. High-contact metal surfaces, such as those in bearings, benefit from smoothing, which minimizes noise and abrasion. Surface peaks can be reduced to an Rpk of less than 0.1 μ while preserving valleys that serve as oil reservoirs. This smoothing process results in a surface that decreases wear and extends the lifespan of tools.

The smoothing process can achieve Ra values as low as 0.01 µ with consistent results. This technique is primarily used in:

Automotive - polishing and smoothing gear wheels, camshafts, and drive units.
Motor Racing - polishing and smoothing valves, gear wheels, pistons, and camshafts.
Forming Tools - polishing and smoothing, forming, and pressing surfaces.
Metalworking Industry - smoothing high-speed spindles.

Deburring and Finishing

Deburring and surface finishing machines are highly effective for mass finishing of plastic, rubber, ceramic, and metal parts. Utilizing these machines in product finishing is crucial for achieving consistent and reliable outcomes.

Wet Finishing

For optimal surface quality, it's important to pair the appropriate process media with each machine. In wet finishing, a water or compound mixture is typically used. This combination helps absorb and wash away debris, ensuring high efficiency during the entire process and preventing media clogging.

Dry Finishing

Selecting the correct process and medium is crucial in surface finishing. Dry finishing involves operations without the use of liquids. To prevent issues or accidents when working with dry abrasive granulates, a sufficiently powerful extraction unit is essential. This method is often employed in polishing, where a polishing paste or powder is applied to the medium. Friction between the medium and workpiece, caused by the finishing process, leads to material removal and produces a polished surface.

Differences Between Finishing, Polishing, and Buffing

Finishing and polishing both utilize abrasives but serve different purposes. Finishing eliminates scratches or surface imperfections caused by cutting or grinding tools, while polishing adds a glossy or lustrous appearance to the material’s surface.

Polishing typically uses abrasive belts, whereas buffing employs cloth wheels treated with compounds. Polishing creates a lined or brushed finish, whereas buffing produces a bright, lustrous finish and removes any remaining lines. Buffing usually requires prior surface refinement through polishing.

Surfaces can be leveled through polishing by using abrasive discs or belts to eliminate scale, pits, and scratches. Buffing is then used to remove polishing lines. The finest abrasives are recommended for polishing to correct levels, welds, and surface imperfections before removing the scratch lines.

In the buffing process, a rotating cloth wheel with fine abrasive compounds is used to achieve a bright, lustrous finish. The buff wheel carries a greaseless compound-based matrix, with the compound performing the actual surface finishing.

Leading Manufacturers and Suppliers

Chapter 3: What are the different types of metal finishing and polishing processes?

Metal finishing is a crucial phase in metal production. The process typically includes several steps: grinding, buffing, sandblasting, metal plating, chemical finishing, electroplating, electroless plating, and other methods.

Benefits of Plating

Improves corrosion resistance
Increases metal durability
Improves surface friction
Improves appearance

Brush Metal

The process involves applying friction to the workpiece, removing imperfections and creating a textured grain for a smooth exterior finish. This method results in a non-reflective surface and is typically performed using abrasive belts or fine bristle brushes. Brushed finishes can be achieved with brush-back sander heads, stainless steel wire wheel brushes, nylon discs, and various types of abrasive cloths.

Buffing Polishing

This process uses abrasive compounds to create a radiant finish on metal surfaces. The abrasive compound is applied to a buffing wheel, which then performs the finishing work. This fine polishing process produces a smooth, lined surface. However, cut buffing requires significant effort, time, and pressure, making it challenging to operate. Finish buffing, on the other hand, refines the surface by removing fine lines to achieve a more radiant finish. It is quicker and easier than cut buffing, requiring less pressure. While effective for smoothing surfaces and rounding edges, this process may not be suitable for applications involving delicate, intricate, or recessed features due to the limitations of the cloth wheel.

Centrifugal Disc Finishing (CDF)

Centrifugal disc finishing, also known as roll flow finishing, is a recent addition to finishing processes, introduced in Great Britain in 1969 and in Germany in 1998. This method utilizes a machine with an open-top bowl, stationary side walls, and a rotary disc at the bottom.

For many years, there has been a need in manufacturing to brighten dull metals, smooth rough surfaces, and soften sharp edges. The traditional approach involves using abrasive finishing media and water.

The early mechanical methods for finishing materials included rotary tumbling and vibratory systems, which have proven to be effective. The development of the centrifugal barrel finisher (CBF) marked a significant advancement, featuring a closed barrel mounted on a rotating turret that exerted substantial force on the parts and media inside.

While the CBF was productive, it required extensive material handling and had longer cycle times compared to vibratory or rotary tumbling systems. Manufacturers sought a method that combined the advantages of centrifugal barrel finishing with faster processing speeds, precise control, and compatibility with modern automation.

This led to the creation of the centrifugal disc finisher, which features a round, rotating disc at the bottom of a stationary chamber. In this system, parts, finishing media, water, and either dry or liquid compounds are placed into the chamber.

When activated, the disc rotates at peripheral speeds up to 2000 sfpm (610 m/min), causing the mass of parts, media, and compounds to move upward and outward against the chamber walls. This mass then slows, tumbles, and falls back towards the disc, where the upward and outward motion resumes, mimicking a natural vortex.

The rapid disc rotation enhances the mass's weight and creates highly efficient, aggressive finishing energy. The rpms of the centrifugal disc finisher can be adjusted to suit different batch requirements.

Centrifugal disc finishers are capable of finishing parts eight to ten times faster than tub or vibratory systems. For instance, a process that takes two hours in a vibratory system can be completed in just 12 to 15 minutes with a CDF. A 2 cu ft centrifugal disc finisher can accomplish the work of a 20 cu ft vibratory system in less than half the time.

Chemical Finishing Processes

These processes involve various methods, such as dipping or washing metals during fabrication. They utilize highly specialized chemicals with unique properties tailored to specific metals. Occasionally, these chemicals are used to achieve dull surfaces through chemical etching.

Edge Rounding

Edge rounding can be categorized into the following types:

Rounding of Cutting Edges

This process aims to stabilize the cutting edges because, in most metals like carbide, edges tend to wear out quickly, especially when there is a load involved.
It is an uncomplicated process of rounding the cutting edge to an approximated length that enhances tool reliability and life whilst making the edge much stabler.

Rounding of Workpieces

The process is to ensure that all burrs have been removed and the result is spotless.
Confirmation that all burrs have been removed gives an assurance that the workpiece is now better protected from wear.
Although all mass finishing processes are well suited for edge rounding, stream finishing is the most efficient one since it offers a shorter processing time than other processes.

Metal Grinding

The process involves rounding edges, creating sharp edges, producing unique effects, smoothing, and deburring. Grinding machines, either stationary or handheld, are commonly used for this purpose. Metal grinding relies on attrition, compression, or friction to achieve a smooth surface. The final smoothness of the surface depends on the type of grinder used. Various grinding methods include surface, electrochemical, centerless, and cylindrical grinding, among others. The choice of method depends on the type of product and metal being processed.

Metal Plating

This is the process of depositing a metal coating onto a surface or workpiece by giving it a negative charge when it is settled in metal salt. A thin metal coating is produced by attracting the negatively charged material to the positively charged. The process can be completed by dipping metal into a metallic solution called electroless plating or electroplating.

Plasma Spraying Coating

Thermal spraying is a process where a surface is coated with molten material at high temperatures. The surface is rapidly heated to a high velocity and then quickly cooled to form a hard, solid coating. This coating provides protection against wear, corrosion, erosion, and high temperatures. When applied correctly, thermal spraying can also alter the electrical and aesthetic properties of the workpiece.

Powder Coating

This process typically complies with environmental regulations and is known for its high-quality results and efficient operation. It involves using polyurethane resin combined with leveling agents, pigments, additives, and flow modifiers. These components are melted and mixed into a powder that resembles baking flour. The powder is then applied to the metal substrate using an electrostatic spray, followed by curing in an oven. Powder coating can also be applied to non-metal surfaces such as certain types of fiberboard and plastic. Additionally, it can be used to eliminate deformities and defects.

Sandblasting Process

This process effectively removes debris, dirt, and particles that accumulate on surfaces during processing. By eliminating the need for post-processing cleanup, it saves time and reduces costs. It offers high efficiency and productivity, being up to 75 percent faster than other methods. The process utilizes various abrasive materials, such as silicon carbide, glass beads, plastic abrasives, aluminum oxide, and corncob grit. These materials produce a range of finishes, from textured patterns to a soft, satiny appearance.

Smoothing Process

The smoothing process provides a cost-effective, quick-cycle method for surface finishing. In the automotive industry, it is ideal for polishing and smoothing components such as gear wheels, pistons, camshafts, expansion screws, rocker arms, and valves. In metalworking, smoothing is used for high-speed spindle finishing, while in tooling, it is applied to forming and pressing surfaces for polishing and smoothing.

Process of Deburring

In the metalworking industry, the term refers to the process of removing sharp edges from metal parts or components after manufacturing or treatment. Stream or drag finishing machines are employed for large and heavy metal pieces that remain separate during processing. Selecting the appropriate abrasive media is crucial to ensure that burrs or sharp edges are fully removed rather than just bent over. Specialized knowledge and experience are required for individuals or teams performing this process.

Chapter 4: What are the different types of finishing machines?

Finishing machines vary in shape, size, and function. This section will provide a detailed overview of different types of finishing machines and their various functions.

One common type of finishing machine is the vibratory finishing machine. Its benefits include, but are not limited to:

They have the capacity to finish soft, large-sized, and fragile parts.
The unloading and loading process is easier.
They can perform thorough colorization and cleaning.
The polishing rate is faster.
They bear a reduced media wear possibility.
The automation process is easier.

Centrifugal Barrel Finishing Machine

This finishing process is more aggressive than the previously mentioned methods. The centrifugal barrel finishing machine uses 3 to 4 barrels mounted on a turret assembly. The rapid processing is due to the high centrifugal forces generated by the turret's high-speed rotation.

The machine operates at variable frequencies to match the required rotational speed for each process, ensuring a more consistent and uniform surface finish. It is predominantly used in industries such as bearing, compressor, automotive, jewelry, textile, and aerospace.

Drag Finishing Machines

This finishing process involves securing workpieces in specially designed holders, which are then dragged in a circular motion through a drum containing polishing and grinding granules. The high-speed movement creates significant contact pressure between the media and the workpiece. This pressure results in precision smoothing and edge rounding that closely resembles manual finishing.

Electroless Plating

This plating technique utilizes chemical reactions in conjunction with an aqueous solution. One method involves covering a surface with a thin metal layer, which is then bonded through heat and pressure. Materials used in plating include composite, gold, chrome, alloy, cadmium, zinc nickel, zinc, rhodium, nickel, and gold. In jewelry manufacturing, plating is applied to achieve gold or silver finishes. Metallizing refers to coating metals onto non-metallic objects or workpieces.

Elliptical Vibratory Finishing Machines

This type of vibratory finishing machine is suited for processes requiring less than 10 minutes of operation. Elliptical machines are effective for removing light burrs and finishing small parts such as bearing cages and ceramic insulation tiles.

Plating Finishing Machine

The plating finishing machine applies a plating layer to the surface of materials to enhance adhesion, strength, friction reduction, decoration, solderability, and other properties. Despite its long history, it remains crucial in contemporary technology. This process often imparts qualities to the material that are not present in the base material, such as an attractive surface, corrosion resistance, and magnetic properties.

Recent advancements have led to the use of liquids for plating workpieces.

Polishing Tumblers

Barrel finishing machines, also known as polishing barrel tumblers, feature 6 or 8-sided rotating drums that can be used for deburring, rounding, or surface treatment. These machines utilize lubricating agents, abrasives, and tumbler media to create friction in the barrel drum, enhancing the effectiveness of the abrasive material. There are two main types of polishing tumblers: wet and dry. Wet tumblers, with their slower cutting rate, produce a finer finish and are more effective at removing excess stock. Dry tumblers, on the other hand, operate vertically and handle materials throughout all stages of finishing.

Barrel finishing machines, sometimes referred to as barrel tumblers, have 6 or 8-sided rotating drums designed for deburring, rounding, or surface treatment. They use lubricating agents, abrasives, and tumbler media to generate friction within the barrel drum, which boosts the effectiveness of the abrasives. The two primary types of barrel finishing machines are wet and dry tumblers. Wet tumblers offer a slower cutting rate, resulting in a finer finish and greater efficiency in removing excess stock. Dry tumblers operate vertically and manage materials through all finishing stages.

Round Bowl Vibratory Finishing Machine

Bowl round machines are horizontal units lined with urethane, featuring a donut-shaped container with an open top. The container includes a vertical eccentric shaft drive centered in the column. Media mass spins around this column in a forward rolling motion. These machines are widely used in the manufacturing industry and help keep parts aligned to prevent damage.

The bowl can be divided into large parts, and the greatest advantage of using the machine is that gates, screens, and ramps can be loaded into the bowl. This will also enable the self-unloading of parts from the finishing machine and media. They are used mostly to finish small parts like screws and rivets, including bigger ones like turbine blades.

Sandblasting Finishing Machine

This type of finishing machine is renowned for its capability to both clean and smooth metal surfaces simultaneously. The machine works by introducing abrasive agents, such as metal pellets or sand particles, into the system at high speeds. The level of finishing is influenced by the speed of the abrasive particles, the duration of the cleaning stage, and the angle of the applied force.

Spiral Tube Vibratory Machine

This is an enhanced version of Round Vibratory Finishing Machines, designed for thorough and efficient separation of parts in just 8-10 minutes. The bowl’s spiral shape improves process efficiency compared to round vibratory machines. Spiral vibratory finishing machines are commonly used in the bearing industry, furniture industry, and for finishing valve bodies.

Stream Finishing Machines

Stream finishing machines, also known as SF technology, represent a modern advancement in mass finishing equipment. The process involves clamping the workpiece and lowering it into a spinning container filled with polishing or grinding media. The combined rotation of the workpiece and the flowing medium generates the finishing motion. This method provides reliable and consistent results in a short amount of time while allowing for selective material removal.

Trough or Tub Vibratory Finishing Machines

This type of vibratory finishing machine is used for degreasing, polishing, and deburring mid-sized parts, including rods, marble and granite tiles, turbine blades, shafts, axles, and aerospace components, among others. Its capacity allows for maximum channel width and facilitates easy separation of parts with removable compartment dividers.

The tub finishers�� structural design is stronger and firmly joined together, giving a U-shaped trough encrusted with a premium polyurethane lining than is fixed on coil-coated springs. The drive has a premium effectiveness motor that controls an offset drive shaft with weights that can be easily adjusted. The increase or reduction of machine combativeness weights is made by adjusting the weights. The system is mostly fueled by a shaft that has an eccentric hook on the tub, a sheave, motor drive, and V-belt are used to rotate or spin the shaft. Eccentric weights may be loaded or unloaded around the shaft to reduce or add vibration.

Unique Machinery for Surface Finishing

Various unique machines employ different techniques. Examples of such machinery include:

Abrasive Blasting Machinery

These machines are commonly used in larger applications to remove scale, rust, or paint from metals at a much faster rate. Abrasive blasting equipment can include chain-fed conveyors or sandblasting systems, capable of processing up to 1000 pounds (454 kg) of steel per hour.

Abrasive Wheel Finishing

This method combines belt sanding with either a drum-style rotating abrasive brush or a cup-style rotating brush. The brushes, made from durable materials and coated with abrasives such as garnet, enhance their effectiveness in surface finishing and material removal. The primary goal of this system is to round sharp edges and deburr the material surface, ensuring safe handling of parts for subsequent use.

Magnetic Polishing

The finishing technique described here is well-suited for metal components with small, hard-to-reach areas such as pockets, chambers, and deep holes. This method involves placing the parts in a container filled with magnetized abrasive particles. These particles work to polish the inner surfaces of the difficult-to-access regions, resulting in a smooth and polished finish. The magnetic polishing method enhances the durability of intricate parts while providing a soft sheen that protects against air and liquid exposure. Not only does this process achieve a high-quality surface finish, but it is also economical and effective in rounding and deburring components to a high degree.

Hot Blackening Equipment

This finishing technique involves applying a black oxide coating to the material’s surface, aiming to improve its appearance and increase resistance to abrasion.

Rumbling or Tumbling

This method facilitates the removal of minor burrs, metal projections, and surface imperfections. The process involves placing components in a container with abrasive media and then using vibration to mix everything thoroughly. This vibratory action helps to eliminate burrs and creates a texture that can be either directly used or easily coated with paints, powder coatings, clear lacquers, or other materials that provide a more resilient finish resistant to scratches and chips.

Sanding Finishing Method

This finishing technique is designed to clean and refine smooth and curved surfaces by creating irregular, non-linear textures. Various abrasive media can be used in this process, with higher grit numbers and finer particles yielding a more refined finish. Finer grits produce a mirror-like polish similar to that on stainless steel, while coarser grits remove material more quickly. The process can be carried out using automated belt systems or manually operated belt sanders, where materials are fed through a rotating belt or other mechanisms to achieve the desired finish.
