Finishing Machine FAQ Guide

1. What is a finishing machine?

Finishing machines offer a broad range of industrial processes geared at altering the shape, form or surface of workpieces.

These machines are used on manufactured items to achieve certain results or meet stipulated requirements.

A finishing machine may thus be employed to improve appearance, wettability, adhesion, solderability or corrosion resistance.

In addition, they come handy for exposing chemical resistance, wear resistance or hardness.

These machines are perfect for modifying electrical conductivity, burrs removal, surface friction control, and resolving other surface flaws.

At other times, these machines help to restore workpiece original dimensions to salvage or repair it.

2. What are the working constituents of a finishing machine?

There are several important components involved in the efficient working of Finishing Machines. They include:

The Machine – These are the essential, interconnected hardware or machine parts that make the finishing process feasible.

Some of the most prominent parts are:

The work tub/bowl/chamber

This is the enclosed space within which the parts are enhanced and mass-finished. It incorporates the media, compound, and water that combine to work on the workpieces. They are usually lined with high quality, wear-resistant elastomer polyurethane.

Water/compound system

Ideally, all finishing machines have control systems that regulate the flow of water and compound for cooling and cleaning effects.

Work Chamber Cover

To put a check on the noise level, finishing machines sometimes come with an acoustic lid or sound isolation cabin.

Electrical controls

Like every other industrial machinery, finishing machines have electrical control systems. The control board includes push-button controls and display units for all machine functionalities.

Water: Water helps normalize the machine’s cooling system, during the finishing process. It also helps wash away scraped materials from the workpieces.

The Media: These are the solid material which put the required touches on workpieces. These controlled materials ‘rub-off’ on workpieces, efficiently fine-tuning workpiece surfaces.

Mass Finishing Vibratory Media

The Compound – These are dry or wet substances that protect the machine itself from corrosion and rust. They are added to the machine to assist in the overall finishing process.

3. How does finishing machine work?

Finishing machines is a general term that refers to machines used for deburring, cutting, smoothing, shaping, polishing or cleaning of manufactured items.

The finishing process involves the loading of the unfinished workpieces into finishing machines like tumbling barrels, vibratory machines, and centrifugal barrel machines. Along with the workpieces, finishing media and compounds are also ushered into it, with or without water. Once the finishing machine kicks into motion, the media graze or rub upon the workpiece while being suspended in the finishing fluids.

The media and compounds have abrasive properties which cause the excess material – that the workpiece is made of – to be abraded away. A finishing machine might be a tumbling machine which are barrels designed to rotate. Or a vibratory machine that’s a tub, meant to vibrate at very high speeds.

4. What are the functions performed by a finishing machine?


Deburring is the process of removing sharp edges or burrs on metals, left after machining.

A common deburring example is smoothening a sharp corner into a rounded corner in a piece of metal.

vibratory finishing metal sheet deburring from machining


This is similar to deburring.

It also smoothens the finish on a metal workpiece.

Descaling removes the leftover machine lines in the process of milling and shape-cutting metals.


Polishing – also called burnishing – take the workpiece to the next level of smoothness.

It makes the workpiece shiny and to attain a mirrored look.

vibratory finishing cleaning and polishing


One of the usages of a  Finishing Machine, is surface cleaning.

They help to cleanse parts from specks of dirt. Such dirt or stain may include grease, dust or other residues stuck on the workpiece, from previous processing.

5. What are the different categories of finishing machines?

Finishing machines are often categorized by how they affect a manufactured workpiece. They include:

Abrasive blasting Finishing Machines

Abrasive blasting machines are those that operate by forcibly propelling a stream of abrasive material against a surface under high pressure.

More commonly known as sandblasting machines, they smoothen and/or roughen surfaces, shape/reshape workpiece surfaces or remove surface contaminants.

Pressurized fluid or compressed air, is used to propel the blasting material (ie the media).

Burnishing Finishing Machines

Burnishing finishing machines make use of a plastic deformation process to enhance parts.

Such friction occurs when the surface has a sliding contact with another object. They essentially help smoothen surfaces and make them shinier.

These machines and their processes may be used on any sliding surface if the contact stress locally exceeds the yield strength of the material.

Grinding/Abrasive Cutting Finishing Machines

Grinding machines use an abrasive machining process that uses a grinding wheel as the cutting tool.

They are capable of producing fine finishes and accurate dimensions.

However, they are usually better suited for finishing very hard materials than “regular” ones.

Compared to “regular” machining, these machines are best suited for taking very shallow cuts.

It’s important to note that most modern finishing machines are usually versatile in functionality ie a burnishing machine can – in addition to its burnishing capability – also grind workpieces.

6. Of what importance is the media to a finishing machine?

A finishing machine can’t perfectly refine or improve surfaces, all by itself.

Finishing media are therefore an indispensable addition to the finishing process.

They help achieve various surface preparation and finishing of workpieces.

Finishing media could be natural like a corn cob and walnut shell media, or artificial media like plastic deburring and ceramic media.

The distinction between them is that natural media provide soft abrasive action on the parts, while artificial media are used for medium to heavy deburring.

Plastic media – being lighter – are used with delicate and fragile parts, while ceramic media is used with heavy parts that need cutting.

Finishing media come in assorted shapes to make handling of different workpiece sizes and patterns, easier. Popular media shapes include cone, pyramid, cylinder, triangle and so on.

plastic deburring media

Finishing media are designed for one or more of four things:

Cutting: Finishing media that cut and remove burrs, also smoothen surfaces. Cutting media helps develop dull, matte surfaces.

Luster: Some grades of media are designed to etch luster finishes on metal surfaces.

These finishing media are generally non-abrasive or have a very low degree of abrasiveness.

They deburr by peening, rather than by actually removing the burr.

vibratory finishing cleaning and polishing

Part separation: Another very important function of finishing media is to separate parts. This occurs during surface improvement or enhancement operations.

Surface scrubbing: Finishing media also can scrub surfaces and cleaning workpieces.

Both abrasive and non-abrasive media are effective in this aspect. They can help remove organic soils, scale, and other inorganic residues.

7. What is the importance of compound to a finishing machine?

Finishing compounds are added to finishing machines to increase deburring action; remove scales; scour surfaces; and clean workpieces.

Additionally, they modify the luster or color of the workpieces by adding corrosion-inhibiting coatings on metallic parts.

Generally, most finishing compounds are combinations of soluble chemicals that form solutions which enhance the action of media against the workpieces.

vibratory finishing machine ready for shipment

Good compounds include water, water conditioners, cleaners, wetting agents, lubricants, foam control agents, pH buffers (pH control chemicals), rinse agents, and emollients.

Some also contain metal brighteners and corrosion inhibitors.

The list of chemicals that a finishing compound may contain, is usually extremely long.

The amounts or percentage of chemicals used, depends upon the results desired and the economics of the manufacturer or user.

However, there are situations where compounds are not used in the finishing process.

For example, some workpieces are sometimes finished dry, perhaps with sawdust, ground corncobs, wood pegs, or other media.

Media for dry finishing is often treated with oil, grease, or wax-based formulation with finely-powdered abrasives to produce smooth surface finishes.

The highlighted functions of compounds include:

  • Keeping the workpieces clean and inhibition of corrosion
  • Enhancing workpiece brightness and helping them develop certain colors after finishing
  • Removal of soil, grease, or oil from parts
  • Provision of corrosion resistance for ferrous and non-ferrous parts.
  • Maintenance of consistent water hardness and level of metal ions

8. What are the ways to best maintain a finishing machine?

Like humans, machines need maintenance – to guarantee their longevity.

To get the most out of a Finishing Machine, certain dos’ and don’ts need to be adhered to. They include:

Periodic Maintenance:

Machines generally need proper and periodic maintenance, including servicing.

Doing this enhances their day-to-day performance and helps resolve internal operation issues.

Ensuring the machine is in good condition before usage:

It’s important to habitually check for internal and exterior damages, before putting the machine into use.

Doing this helps safeguard the workplace from preventable accidents, including spillings, outbursts, and so on.

Monitoring the media, compound, water level:

For no reason whatsoever should you allow these levels to become too lowered.

Some deliberately reduce media level to save money or to mass finish more workpieces.

The consequence ranges from slow process time to component damage, to non-qualitative finishing.

9. What industries can best take advantage of a finishing machine?

Finishing Machines are generally versatile and are usable in all manufacturing industries.

Some of their specific industrial usages include:


It’s a known fact that pieces of jewelry that have been neglected for so long and are improperly kept, accumulate specks of dust and varying other particles.

These impurities combine to start having unimaginable effects on the prior-enticing surfaces of these items.

Jewelry shops, therefore, make use of finishing machines to return jewelry items back to an enhanced state.


General Job Shop:

At general machine shops, finishing machines provide cost-effective, quick enhancement for varieties of items and parts.

10. What are the benefits of using a finishing machine?

Several benefits accrue from the usage of finishing machines. The prominent ones among them are:

Corrosion Resistance

Finishing machines help to eliminate roughness and micro-notches in a workpiece.

It helps give a workpiece greater resistance against rust and other forms of metal corrosion.

In essence, a properly finished workpiece is less likely to develop cracks and other imperfections.

Strain Hardening

Finishing machines help condense the structure of inserted metallic workpieces to increase its hardness.

A finished workpiece is 50 to 100% harder than its unburnished counterpart ie one with a mill finish.

This makes it more resistant to fatigue failure.

Polished Finish

Not only is a finished workpiece stronger, but it also becomes more polished.

Finishing machines effectively eliminates minor visual defects by polishing the surface to the smoothness that’s desired by an operator.

11. What is the flipside to using a finishing machine, if any?

The usage of finishing machines comes with several side effects, which its users must take note of before employing the processes.

Indeed, many of these side effects are beneficial, but some may not be -depending on your reason for finishing a workpiece.

In addition to enhancing workpiece surfaces, finishing machines can also:

  • radius or blunt part edges
  • change part dimensions
  • compact a part’s surface “pores”
  • remove oxides and heavy scale from a part
  • change a part’s flatness
  • prevent electroplating adhesion (if the wrong media is used)
  • prevent soldering (if the wrong abrasives are used)
  • cause blowholes in welded joints (if the wrong abrasives are used)
  • create large compressive stresses on a part
  • cause dings, scratches, and dents to a part
  • improve or worsens corrosion rates
  • change part luster
  • change part color
  • change friction
  • decontaminate radioactive surfaces

Essentially, the key is to determine what your needs are, and making sure to make the right choice of finishing equipment.

It’s also important to make use of appropriate media, as well as finishing compound.

12. How much does an average finishing machine cost?

It’s perhaps impossible to put a price tag on the average cost of a finishing machine.

The reason for this is that various indices contribute to determining the purchase price of a finishing machine.

Such indices include the horsepower, size, type and in some cases, the manufacturer of the finishing machine.

13. What are the step-by-step processes of using a finishing machine?

No matter the type and category of finishing machines, they all more or less, share the same type of operating processes.

The first step is to determine the most appropriate process and equipment to use.

Generally, this requires numerous discussions with finishing equipment vendors.

automatic fully centrifugal disc finishing machine

After arriving at the perfect machine choice, there are some other considerations to make. They are:

  • Determining the required degree of finishing that’s needed.
  • Determining the allowable size change by reviewing piece part tolerance.
  • Estimating the starting burr size.
  • Determining the required cycle time needed for the result.
  • Selecting an appropriate media size for the workpiece size
  • Verifying that the media will not lodge in the workpiece
  • Determine what subsequent operation might be affected by the media or compound choice (welding, soldering, plating, etc).
