Barrel Tumbling Machines

The barrel finishing and barrel tumbling machines are one of the oldest ways for surface finishing. It is typically used for industry metal surface deburring and polishing. Nowadays, it still widely used for delicate component surface deburring and polishing. Especially for the plastic button, plastic glass frame as well as other precision components.

Inovatec offers single barrel design rotary barrel tumbling machines and double barrel tumbling machines.

The workpiece is mixed with abrasive media, (here called mass) is charged up to the half of barrel tub.

When barrel tub rotates the mass rises up to top dead center and then top parts of mass begin sliding towards like “avalanche”, which is called “sliding layer”

The relative speed difference between the workpiece and abrasive media produces friction which will finish workpiece efficiently


1. Hexagonal design barrel vs Olive Shape Barrel

The olive shape barrels gain design concept from Triple action barrels. The olive barrel action folds the media axially as well as horizontally. This combined sliding and folding action are reportedly significantly faster than the normal horizontal machine.
