1. What Are Tumbling Machine Stones?

The tumbler machine stones are the materials that are added along with the manufactured parts in a mass finishing machine for finishing parts.

Such tumbling machine stones are made up of different materials and abrasives.

The abrasive strength of the tumbler machine stone will be different for different types of stones.



2. What Is The Use Of Tumbler Machine Stones?

You can use the tumbler machine due to the following reasons.


2.1 For part support inside the tumbler

The tumbler machine stones provide excellent support to the parts inside the finishing machine while tumbling.

It ensures that the unnecessary movement of parts that can damage the parts inside the finishing machine is avoided.


2.2 Protects part from hitting against each other

The tumbler machine stones will ensure that there is no part to part contact during the finishing process.

It will be present between different parts.

So, it will help to avoid the part to part collision.

It is also useful for protecting the parts from hitting against the tumbler walls.

So, it protects the parts from all sorts of damages.


2.3 Applying abrasives to workpieces

The tumbler machine stones will be in touch with the parts all the time inside the tumbler machine.

So, they will apply the abrasive on the part surface for deburring, cleaning, and finishing purposes.


3. Why Should You Use Tumbler Machine Stones?

Let us look at the various processes done by the tumbler machine stones during the mass finishing process.


3.1 Deburring

The manufactured part will have an unwanted deposit of material in them.

These are called burrs.

You need to remove these burrs to get the final finished part.

The process of removing the burrs from the part is called deburring.



3.2 Degreasing

The parts may have grease, oil, dirt, and dust on it.

So, these things need to be removed from the part to clean the part.

They are formed either due to the manufacturing process or due to part handling.

The process of removing it is called degreasing.
