Chapter 1: What are Finishing Machines?
Finishing machines are machines used for metal finishing, which is the last stage of the metal fabrication process; the stage encompasses the use of machines in finishing the metal surface. This process gives metals a smooth and rightly shaped look or result. Tumbling media, plating, and loose abrasives are some of the materials that give aid in achieving the process.
Metal finishing may also encompass the execution of a process for cleaning, polishing, and improving a surface. The process also includes electroplating. The metal finishing industry encompasses a wide range of procedures or processes, each of them offers their own user benefits. It also includes the process of cleaning, revamping, or polishing a surface.
There are several machines that are used in metal finishing, and they vary in capabilities and efficiency. The effectiveness of finishing machines differs depending on size and capacity. This article will delve deeper into the essential finishing machines and their diverse and unique qualities.

Enhancing product look
Guards against surface defects
Chapter 2: Approaches in Metal Finishing/Polishing
There are various approaches used to accomplish metal finishing. These are detailed below.
Metal Polishing
Metal polishing smoothes surfaces by making use of an abrasive material. This frees metal object surfaces of defects and makes them shiny, and reflective with an enhanced appearance. In some cases, metal polishing is used in conjunction with buffing - which is not as harsh on the metal surface. As a method, metal polishing has cosmetic value. It also removes oxidation beneath the metal surface thereby preventing metal corrosion giving it a prolonged life.
Metal Polishing Process
The metal finishing process can be accomplished using a variety of abrasives where the material to be polished determines the abrasive to be used. When polishing unfinished material, different stages have to be followed. Firstly, imperfections should be removed from the material using a rougher abrasive. In subsequent stages, finer abrasives are used which 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 in some cases lubricants such as kerosene or wax can be used. Die grinders, stationary polishers or specialized equipment can be used to give a brighter shine during buffing.
A very fine grit that is copper plated can be used for softer metals such as brass to smoothen the surfaces. The metals are buffed using an airflow mop. Tools such as hammers, wrenches, screwdrivers and chisels use different polishing approaches due to their uniqueness. The tools firstly undergo roughing through the use of a grinding wheel. Dry polishing materials are then used to finish the materials. Grease can be applied in instances where extra polishing is needed.
The polishing improves the quality of the surface, reduces friction and wear.
Abrasives Used in Polishing
Different abrasives are used for different metal strengths in the polishing process.
Metals with low tensile strength such as copper, brass, and aluminum use gray silicon carbide abrasives. This abrasive type can also be used on cemented and gray iron carbide.
Metals with high tensile strength, such as carbon and alloy steel, non-ferrous and iron alloys, and abrasives such as white and gray aluminum oxide are used. Green chromium oxide abrasives are used on ferrous metals like steel.
Leather and canvas can be used on polishing. The materials can also include felt, plastic, wool, rubber, etc. Mops or buffing wheels use wool cloth or cotton.
Applications of Polishing
Polishing is necessary in manufacturing processes for products such as kitchenware, cookware, automobile parts, and architectural metal before being released into the market. Metals can sometimes be polished to restore or repair the parts.
Workplace safety can also be enhanced by buffing and polishing. As an example, buffing can aid in corrosion prevention in specialty plumbing. In pharmaceutical and dairy pipes, mold and bacteria can be destroyed and corrosion is prevented thereby enhancing product safety.
Metal Smoothing
Extremely flat surfaces can be generated from mass finishing. Metal surfaces with high contact surface ratio like bearings can be generated from smoothing thereby reducing noise generation and abrasion. The surface peaks can be reduced to Rpk < 0.1 μ while retaining the valleys which can be oil pockets. The smoothing process gives a surface that reduces wear and enhances tool life.
Ra values can range up to 0.01 µ can be achieved uniformly from the smoothing process. This is mostly applied in:
Automotive - for example polishing and smoothing gear wheels, camshafts and drive units.
Motor racing - for example in polishing and smoothing valves, gear wheels, pistons and camshafts.
Forming tools - for example in polishing and smoothing forming and pressing surfaces.
Metalworking industry - for example in smoothing high speed spindles.
Deburring and Finishing
The use of deburring and surface finishing machines is effective or efficient in pile or mass finishing of plastic, rubber parts, ceramic, and metal parts. The use of such machinery in product finishing is of paramount importance in yielding consistent results.
Wet Finishing
There is a need to use the right choice of process media in conjunction with the individual machine to get quality surfacing. A water or compound mixture is normally used for wet finishing. This ensures that particles of debris are absorbed and rinsed away, maintaining high efficiency throughout the whole processing cycle and keeping any clogging on media.
Dry Finishing
In surface finishing choosing the right process and combination medium is of paramount importance. Dry finishing is based on dry operations. There is a need for the use of a sufficiently powerful extraction unit to avoid any problems or casualties when dealing with dry abrasive granulates. This kind of finishing is mostly used for polishing by sticking a polishing paste or powder on the polishing medium. The medium and workpiece experience friction due to movement caused by the finishing process. This results in material stock removal and a well-polished surface.
Differences Between Finishing, Polishing, and Buffing
Both finishing and polishing make use of abrasives. However, finishing removes scratches or surface defects that will have been created from the use of cutting or grinding tools. Polishing provides a gloss or luster on the material surface.
On the other hand, polishing uses abrasive belts while buffing uses cloth wheels that have compounds applied. The polishing process gives a lined or brushed finish while buffing gives a bright luster finish and removes lines. Buffing generally needs surface refinement polishing to precede the buffing.
The surfaces can be leveled through polishing using abrasive discs or belts to remove scale, pits, and scratches. The polishing lines can then be removed by the buffing. The finest abrasive should be used when polishing to remove levels, welds, and surface imperfections. Thereafter, the polishing removes the scratch lines.
During buffing, a rotating cloth wheel with fine abrasive compounds is used to produce a luster finish that is bright. The buff wheels also have a greaseless compound-based matrix termed compound. The buff wheel is the compound carrier and the compound essentially does the surface finishing.
Chapter 3: Types of Metal Finishing/Polishing Processes
Metal finishing is the critical stage of metal production. The metal finishing process is as follows: grinding, buffing, sand blasting, metal plating, chemical finishing, electroplating, electroless plating, and so forth.
Plasma Spraying Coating
The process known as thermal spraying involves coating the surface using a molten material at an elevated temperature. Rapid heating of the is done at high velocity then suddenly cooling to give a hard solid coating. This coating protects the metal from wear, corrosion, erosion, wear, and elevated temperatures. The process can result in changing workpiece electrical and appearance properties when applied right.
Sandblasting Process
This process helps in getting rid of debris, dirt and particles that can pile up on a surface throughout the process. This saves time and cuts costs as there will be no time needed to clean the surfaces after the processing. The process offers high efficiency and productivity since it is up to 75 percent faster than other methods. The process makes use of abrasive materials like silicon carbide, glass beads, plastic abrasives, aluminum oxide and corn-cob grit. The materials produce different finishes from textured designs to a soft satiny look.
Brush Metal
The process exerts friction on the workpiece extracting imperfections and giving a textured grain leaving a smoothened exterior finish. The process leaves a non-reflective surface and is done using an abrasive belt or fine bristle brushes. Brushed finishes can be achieved by the use of brush back sander heads, wire wheel brushes that are stainless steel, nylon discs, and many other abrasive cloth types.
Chemical Finishing Processes
These come in distinct types that include dipping or washing of metal during the metal fabrication process. The process involves the use of extremely specific and exclusive chemicals with peculiar features designed for specific metals. Sometimes they are used to create dull surfaces through chemical incision.
Buffing Polishing
This process makes use of the abrasive compounds in order to produce a radiant finish on the metal surface. The process is achieved through the application of the abrasive compound onto a buffing wheel, where the finishing is done by the wheel. A smooth lined surface is achieved through this fine polishing course process. However, the cut buffing process requires much effort, time and pressure, making it difficult to operate. Finish buffing then extracts fine lines giving a more radiant surface. Finishing buffing is a much quicker and easier process that demands less pressure. The process smoothens surfaces and rounds out edges. The process is not as efficient in applications that need fragile, intricate, or recessed features due to the cloth wheel’s limited range.
Metal Grinding
The process completes round edges, creates sharp edges, produces unique effects, smooths, and deburrs. Stationery or handheld grinding machines are the two common types of grinding machines. Use of attrition, compression, or friction to smoothen the surface is the principle behind metal grinding. The smoothness of the finished surface is dependent on the grinder used. The different grinding methods are as follows: surface, electrochemical, centerless, cylindrical, and many others. Choosing the perfect methods depends on the product and metal type.
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.
Benefits of Plating
Improves corrosion resistance
Increases metal durability
Improves surface friction
Improves appearance
Powder Coating
This process usually abides by environmental regulations and is also a process that is associated with quality produce and efficient processing. It makes use of polyurethane resin merged with leveling agents, pigments, additives, and flow modifiers that are melted and mixed in a powder that seems like baking flour. The powder is applied to the metal’s substrate using an electrostatic spray and then an oven is used to cure the parts. Powder coating can also be applied to nonmetal surfaces like certain classes of fiberboard and plastic. The process can also be used to get rid of deformities and defects.
Smoothing Process
The smoothing process offers a short cycle and low unit cost way of surface finishing. In automotive, it is best suited for polishing and smoothing gear wheels, pistons, camshafts, expansion screws, rocker arms and valves. In metal work smoothing is done for high-speed spindle smoothing and in forming tools for forming and pressing surfaces’ polishing and smoothing.
Process of Deburring
The term is mostly used in the metal working industry to depict the process of removing sharp edges from metalwork pieces or parts after manufacture or treatment. Stream or drag finishing machines are used for large and heavy metal pieces that are not combined during the processing. Choosing the suitable abrasive media is essential since the burs or sharp edges are to be completely removed not just bent over. Specialized knowledge and experience are a necessity for anyone or team that will carry out the process.
Edge Rounding
Edge rounding is characterized into the following:
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.
An uncomplicated process of rounding the cutting edge to an approximated length enhances tool reliability and life whilst making the edge much stabler.
Rounding of Workpieces
The process is to ensure that all burs have been removed and the result is spotless.
Confirmation that all burs 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.
Chapter 4: Types of Finishing Machines
Finishing machines come in different shapes, sizes, and functions. This part will give a more thorough detail of the finishing machines and their divergent functions.
A common type of finishing machine is the vibratory finishing machine. They have several benefits which are but not limited to:
They have the capacity to finish soft, large-sized, and fragile parts
The unloading and loading process is easier
The ability to perform thorough colorization and cleaning
The polishing rate is faster
Bears a reduced media wear possibility
The automation process is easier
Vibratory Finishing Machine
These have a bowl lined polyurethane that is positioned on springs and made of vibratory motor and imbalance masses to give gyroscopic motion. This is used for descaling, polishing, smoothening, degreasing, mirror finishing, and edge control for several components. This method is used mostly for deburring and polishing like molded, forged, sheet metal, machined, and cast parts.
This type of machine can be used to process a wide range of components like aerospace, consumer products, automotive, and defense. To give a dampening effect, water may be used as it helps lower the cutting rate. This comes in handy operations like burnishing where a minimum cut-rate is mandatory. The vibratory finishing machine encloses metal in extreme frequency motion with up to 1800 vibrations per second.
Round Bowl Vibratory Finishing Machine
The bowl round machines are urethane lined horizontal machines with a donut shaped container that has an open top. The donut shaped container has a vertical eccentric shaft drive that is well proportioned across the center column. Around the center column there is a media mass spinning in a rolling forward motion feed. These are the most common types of machines used in the manufacturing industry. The machine helps keep parts comparatively oriented to avoid any 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.
Spiral Tube Vibratory Machine
This is a modified version of the Round Vibratory Finishing Machines. They ensure a thorough and complete separation of parts in a brief time of 8-10 minutes. Process efficiency is considered better compared to the round vibratory machines; this is due to the bowl’s spiral shape. The spiral vibratory finishing machines are commonly used in the finishing of parts for the bearing industry, furniture industry, and valve bodies.
Elliptical Vibratory Finishing Machines
This type of vibratory finishing machine is used in industries where there is less than 10 minutes processing time. The elliptical machines are used for extracting light burrs and for small parts finishing like bearing cages and ceramic insulation tiles.
Trough or Tub Vibratory Finishing Machines
This type of vibratory finishing machines is used in degreasing, polishing, and deburring of mid-sized parts such as rods, marble and granite tiles, turbine blades, shafts, axles, aerospace parts and a lot more. In their capacity they give a maximum channel width and enable parts to be separated easily 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 done through 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.
Centrifugal Barrel Finishing Machine
This finishing process is more combative compared to the finishing method above. The centrifugal barrel finishing machine operates using 3 to 4 barrels that are attached to the turret assembly. The fast process is because of the high centrifugal forces that are triggered by the turret’s high-speed rotation.
To operate the machine in line with the rotational speed needed per process, variable frequencies are used and the process results in a more even and uniform surface finish. The industries in which the machine use dominates are but not limited to bearing, compressor, automotive, jewelry, textile, and aerospace.
Polishing Tumblers
The Barrel finishing machines are sometimes called polishing barrel tumblers. They have 6 or 8 sided rotating drums that can be deburred, rounded, or surface treated. Lubricating agents, abrasives, and tumbler media are used to create friction in the barrel drum and to increase abrasive material effectiveness. There are two basic varieties for barrel polishing tumblers which are the wet and dry tumblers. Wet tumblers have a slow paced cutting rate that produces a finer finish, and this makes them more efficient in the removal of excess stock. Dry tumblers operate using a vertical essential in handling materials across the entirety of the finishing stages.

Dry tumblers operate using a vertical essential in handling materials across the entirety of the finishing stages.
Sandblasting Finishing Machine
This type of finishing machine is well known for its ability to perform both the cleaning and smoothening of the metal all at once. The machine operates by inserting abrasion agents such as metal pellets or sand particles in the setup at an accelerated speed. Speed of the abrasion particle, duration of the cleaning stage and angle of the prepared fire, determine the level of finishing.
Plating Finishing Machine
The plating finishing machine operates by inserting a layer of plating on the surface of the material to achieve adhesion, strengthening, friction reduction, decorative, solderability resistance, and a lot more properties. Even though this process has been done from way back, it is still of paramount importance in modern day technology. Usually, the material possesses a desired quality that is not on the main material. It may also offer the following: attractive surface, resistance to corrosion, and magnetism.
Modern day findings have necessitated the plating of workpieces with the aid of liquids:
Electroless Plating
This type of plating involves the use of chemical reactions simultaneously with the aid of an aqueous solution. One the plating method occurs when a surface is concealed by a thin metal sheet, an application of pressure and heat is done to merge them. In plating the following materials are used: composite, gold, chrome, alloy, cadmium, zinc nickel, zinc, rhodium, nickel, and gold. In the jewelry manufacturing industry plating is done to a gold or silver finish. Metallizing is coating metal onto nonmetallic workpieces or objects.
Drag Finishing Machines
This finishing process involves the clamping of work pieces in holders that are specially designed, following the dragging of the holders in circular formatting through a process drum with polishing and grinding granules. The accelerated speed movement produces an elevated contact pressure in the midst of the media and workpiece. The pressure then results in the perfect forming of high precision smoothing and edge rounding that seems like it has been done manually.
Stream Finishing Machines
They are called SF technology and they are a great presentation of modern-day mass finishing machinery. The process involves the workpiece being clamped and lowered in a holder into a spinning container, polishing, and grinding a medium filled container. The independent rotation of the workpiece and the flowing polishing or grinding medium are both responsible for generating the real finishing motion. This process gives reliable and consistent results in a short finishing time whilst enabling a selective removal of materials.
Unique Machinery for Surface Finishing
Unique machinery exists and uses various techniques. Examples of such machinery include:
Rumbling or Tumbling
This kind of technique offers the removal of small burrs, metal points, and surface finishing. The tumbling process entails inserting components in a box together with abrasive particles and then vibrating the machine to combine everything together. The vibratory process extracts burrs and gives a fleck that can be used directly or coated easily using paint, powder coat, clear lacquers, or any other material that gives a more durable finish that won’t yield to scratching and chipping.
Sanding Finishing Method
This finishing method is used for cleaning smoothened and curved surfaces through the process of forming irregular, non-linear textures. This method can involve different abrasive media and a higher grit number plus finer or smaller particles give a more elegant finish. Finer grits result in mirror polish like stainless steel whilst coarse grits help in getting off materials at a faster rate. The machines can be a more automated belt system, or a belt sander operated manually that passes down materials to be processed below a rotating belt or more as per need to achieve the desired outcome.
Magnetic Polishing
This finishing process is ideal for metal areas with smaller parts that may be hard to reach pockets, chambers, and deep holes. Magnetic polishing process entails putting components in a tub or box that will be filled with magnetized particles. Particles are directed to rub the inner parts of the hard-to-reach spots giving a smoothened and excellent polish. The magnetic polishing process gives intricate parts resistance and soft polish that makes it resistant to air or liquids. The process yields excellent results by giving a perfectly finished surface and is at the same time cost effective. The finishing process does not only yield to improved surface quality but also rounding and deburring to a specifically expected degree.
Abrasive Wheel Finishing
This method uses the belt sanding method together with either a drum style rotating abrasive brush or a cup style rotating brush. The brushes are made from a resilient material and coated with abrasives like garnet to increase strength through surface finishing and material removal properties. The main aim or purpose of the system is also to round sharp edges and deburring the material surface to ensure safe handling of parts for later use.
Abrasive Blasting Machinery
These are often used in larger applications and can remove scale, rust, or paint from metals, at a much faster rate. The abrasive blasting machinery can be a chain fed conveyor or operated sand blasting system that can process 1000pounds of steel per hour.
Hot Blackening Equipment
The type of finishing process entails coating of material’s surface with black oxide in a bid to enhance the look and the abrasion resistance.
Other Types of Metal Finishing Equipment

Chapter 6: Choosing the Right Finishing Process and Finishing Machine
This chapter will discuss considerations when choosing the right finishing process and the right finishing machine.
Choosing the Right Finishing Process
The finishing process is the last stage in the production of perfect product texture and look complementing workpiece design and giving protection from rust, tarnishing, and corrosion while adding to strength, thickness, durability, and hardness to the finished product.
Costs Considerations
Cost is the first consideration in the production process, for example types of costs like the type of coating, expended energy, various consumables, amount of waste, cleanup, and labor costs.
Type of Metal
There is also a need to know the type of metal to process in order to choose the right finishing process and machine. The types of metal differ from aluminum to stainless steel, thus there is a need to understand all the types and find a more profitable result.
Time Constraints
There is a need to know the processing time for different processes in order to choose one that meets the time constraints of the project. A careful consideration of time constraints will help meet deadlines whilst ensuring a more efficient processing time. Careful consideration of time can also help maintain stability in the supply chain system whilst avoiding costs and errors that may come from working at the last minute.
Electroplating Process
The degree at which a metal can be fabricated and manipulated is determined by the durability, strength, and endurance of the metal. Metal strength is dependent on the types, use, and different applications. The three factors to determine metal strength are ultimate, yield, and breakable strength. Yield refers to a metal deformation period whereas ultimate means the level of stress a material can endure. The metal fabrication process success is dependent on the choice of the finishing process and a right choice or decision saves labor, cost, and time.
Choosing the Right Deburring and Finishing Machine
Various considerations are necessary when deciding on the right deburring and finishing machine. These include:
Machine and Workpiece Compatibility
Choosing the right machine that is consistent with the needs of the finishing process requires one to make sure the machine serves its intended purpose. The dry machines are most suitable for an industry where similar materials are ground consistently.
Workpiece Qualities
For industries where there are distinct types of materials involved, wet deburring and finishing machines are the best choice. A consideration of the workpiece’s qualities and specific characteristics as well as the type of abrasive is essential in ensuring the maximum performance of a machine.
Labor Force
There is a need to consider the labor force characteristics that will assist in the process, for example the number, technical expertise and so forth. More people involved in the process means the choice of machinery is also open to high maintenance machines. A more skilled labor force means they can work with automated machinery.
Project Time Constraints
The more time a process or project takes means more money is used and also may cause problems in the supply chain if products don’t meet the expected date. There is a need to choose a machine that goes along with the production allotted time.
Project Costs
The choice of finishing machinery should be within the allocated budgeted amount. That is, one is supposed to factor in the cost of operating the machine, whether one can afford the technical expertise to operate and maintain the choice of machine. Without careful consideration of such a key factor may affect the quality and quantity of products from the process.
Professional Opinion
Making a perfect choice for a deburring or finishing machine is not for the faint hearted, thus the need to get help from the professionals. In this case, one may find it helpful to consult metal fabrication experts. There are a few factors to be considered during the selection of the expert to consult, which are not limited to: relevant industry experience, whether they have the right manufacturing partners, and references from previous customers so you can know the kind of services they or offer.
Conclusion
It has been proven that metal finishing is as important in the production process as any other stage. To produce resilient, strong, and well-presented products, it is essential to pay much attention to what finishing suits a specific item. Workpiece characteristics have a lot to play on the choice of finishing process and machinery selected.
