Centrifugal Disc Finishing Machines Introduction

A centrifugal disc finishing machine uses high-energy mass finishing process to create the desired surface finish. It can offer almost 10-30 times stronger abrasive action compared to conventional vibratory finishing. As a result, these machines are suitable for removing tough burrs and imparting high-intensity finish for small and medium workpieces.

During the process, the mixture of tumbling media and workpieces gets accelerated and starts moving upward. When it comes in contact with the barrel wall, it slows down and starts rolling back to the center again. This action keeps repeating at high speed until you get the desired finish. It also reduces the chances of parts colliding with each other.



In other words, a centrifugal disc finishing machine creates a smooth surface finish in a relatively short time. The most common applications include deburring, surface grinding, and polishing of coins, chain tabs, sliders, stampings, castings or machined parts.

You can find manual, semi-automatic, and fully automatic variants of a centrifugal disc finishing machine at Inovatec. Choose the one that fits your requirements.

9. What Is A Centrifugal Disc Finisher Machine?

The centrifugal disc finisher machine will provide a faster action on the parts with the help of the 3-dimensional action of the vibratory bowl along with the fast cycle time of the machine.

The cutting action of a centrifugal disc finisher is ten to thirty times faster than the other mass finishing machines.



They are high energy finishing machines that work on the principle of centrifugal force.

You can quickly load and unload parts into a disc finisher with the help of the manual or electric tilting motor unit.


10. Can You Explain The Working Of A Centrifugal Disc Finishing Machine?

This machine is capable of aggressive material removal from the parts to mirror like shine on the part surface through polishing.

The action of the machine on the parts is entirely dependent t on the speed of rotation in RPM and the amount of water and compound mixture inside the bowl.

The centrifugal disc finisher machine will have a spinner disc at the base of the machine.

The motor generates the force which is transferred to the spinner disc to convert it into a spinning motion.

Thus, the media and the part mixture is made to move in the upward direction inside the bowl.

So, it will go and rub on the polyurethane lining inside the bowl.



This process will happen continuously throughout the entire finishing time.

This continuous action of roll and flow makes the process faster and efficient.

The media and the parts mixture are pushed continuously into the sidewall of the bowl in the outward direction.

It results in the building of pressure.

So, the mixture of media and parts in the upward direction of the sidewall.



After some time, the mixture falls back to the center of the bowl.

This action cyclically continues inside the machine.

The system finally pivots after completing the centrifugal process.

Once the machine pivots back to the finishing position, then the part and the media mixture will get loaded back into the bowl from the hopper section.

So, the machine is ready to finish for the new part mixture.


11. What Are The Different Components Required For Finishing Using A Centrifugal Disc Finishing Machine?

The list of components that are essential to complete a typical centrifugal finishing process is given below.


11.1 Machine

The centrifugal disc finisher machine consists of different parts.

The list of parts is given below.


Working Bowl

It is the chamber/container inside which the media, compounds, and water act on the parts for cleaning and finishing.

There will be lining inside the bowl to provide a cushion effect to the part and media mixture.

This lining will be made of high grade polyurethane.

It will protect the parts and media from hitting against the bowl wall.

It also helps to provide a grip to the mixture of parts and media for proper finishing.


Spinner Disc

The spinner disc is responsible for transferring the force generated by the motor into the bowl for finishing action.

The disc is designed to follow the principles of centrifugal force for action.

It will have a lining of high grade durable polyurethane.


Water and Compound Processing System

Almost all types of centrifugal finishing processes make use of a mixture of compounds and water for finishing.

So, using a system to process the water and compound mixture can be highly beneficial.

It helps to regulate the flow of water into the machine.


Electrical Control Panel

The centrifugal disc finisher machine will come with an electrical control panel.

It can either be an integrated panel or a standalone one.

Push buttons and the display are the two user interfaces provided along with the machine.

Water helps to reduce the frictional effect and also to clean the parts from dirt and dust.

Sometimes compounds are added to the tumbling mixture for specific purposes.

Certain compounds help to inhibit the corrosive effect of water on the metal surface.

Some compounds are used to polish the parts to give an extra shine.


11.3 Media

Media is made up of abrasives.

Abrasives are fused with different types of materials to get the media.

The strong centrifugal force from the machine makes the media hit and rub the parts for finishing.

You can use different varieties of media to get the desired level of finish for the parts.

The deburring process helps to remove the burrs from the part.

These burrs are formed as a result of the manufacturing process.

The removal of burr is essential as their presence weakens the part and can harm the user.

A manufactured part will have raised edges on its sides that need to remove.



14.2 Smoothening the Surface

The centrifugal disc finisher machine helps to smoothen the part surface in such a way that a low RMS finish is achieved.

The type of final finish depends on the kind of media.


14.3 Polishing

Polishing helps to bring that extra shine on the part surface.

You can achieve different levels of shine on the part according to your design requirements.

You may have to use polishing compounds to get a mirror-like shine on the surface.

Different polishing media used include plastic, ceramic, and porcelain.


15. What Is The Difference e Between A Centrifugal Disc Finishing Machine And A Centrifugal Barrel Finishing Machine?

The barrel finisher machine makes use of rotary action to finish the parts.

Here, the parts are made to slide with the media for cleaning and finishing.

The barrel finishing machine also makes use of the centrifugal force for cleaning.

This force is 20 to 30 times stronger than the gravitational force.

The centrifugal disc finisher machine uses a rotating disc to create the centrifugal force for cleaning.

This disc is located at the base of the machine.

The disc will move in the direction of the sidewall to create the centrifugal action.


16. What Is The Difference Between Centrifugal Disc Finishing Machine And The Centrifugal Vibratory Tumbling Machine?

The rotating disc, located at the base of the machine, is responsible for the finishing action in a centrifugal disc finishing machine.

So, an additional part is required for the disc finisher, which is a downside.

The centrifugal vibratory tumbling machine makes use of the sideways movement of the tun in a circular pattern to finish parts.

So, the rubbing of the parts with media will help to clean and polish the pieces.



17. What Are The Different Parts Supported By A Typical Centrifugal Disc Finishing Machine?

The faster action of the centrifugal disc finisher makes it very popular amongst different businesses.

So, this solution is an effective one.

The power of the centrifugal force inside the machine is almost 3o times the gravity.

20.1 Sidewall Lining Check

The frequent use of the machine may result in wear and tear of the sidewall lining.

You need to check the sidewall lining regularly to ensure that you replace it at the right time.

Otherwise, the tumbling media may end up drilling holes in the walls of the bowl.

So, it will impact the life of the machine if you don’t do the replacement quickly.


20.2 Water Level Checking

When you are wet tumbling, you need to ensure that the bowl is filled correctly with adequate water.

Running the machine dry may increase the risk of damaging the disc and bowl of the machine.


20.3 Media Level Stabilization

If you are in the thought process of using fewer media quantity than the amount recommended, then we strongly recommend avoiding such thoughts.

You may end up damaging your parts by lowering the media quantity.

The quality of the finish gets compromised in the whole process.



20.4 Overloading the machine with more workpieces

You may get tempted to load more parts into the machine to increase productivity.

But, we strongly recommend maintaining a minimum part to media ratio of 1:3.

When you load more parts, then the chances of parts hitting against each other are more.

So, the part may get damaged due to collision.

You can always refer to the detailed instructions in the manual to know about the part quantity.


20.5 Sieving Out Undersized Media

The risk of media getting stuck in the gap is more if the size is too small.

So, the media needs to be sieved out of the mixture.

If you are using the CD series centrifugal disc finisher machine, then all the media which are below the 4mm size needs to sieved out.


20.6 Gap Checking

When you use the machine for a long time, the gap between the barrel and disc increases.

So, you need to check this gap regularly to ensure the smooth working of the machine.

You need a proper fix when the gap becomes too small or large.

The gap varies for different models of Inovatec centrifugal disc finishing machines.

The gap for the VA series is in the range of 0.2-0.5mm, CD series is 0.5-0.7mm, and zero gaps for the CF series machines.


20.7 Water Temperature Checks

If you run the machine for 2 hours or above, then the bowl will become hot.

You can reduce the temperature of the bowl by feeding it with cold water.

If you don’t bring down the bowl temperature, then the PU lining may get damaged.


21.  What Are The Different Types Of Media That Can Be Used With A Centrifugal Disc finishing Machine?

You can use centrifugal disc finishers on parts made of different materials.

The media choice is wholly dependent on the part material.


The different varieties of media that can be used with a centrifugal disc finisher machine include the plastic media, ceramic media, steel media, porcelain media, and corncob granules.
