Tumbling machines

How does it work?

In the tumbling machine, there is a continuous mutual movement of workpieces and tumbling media. The movement in the tumbling machine is powered by an oscillating exciter, a centrifugal force or a towing device.

What materials could be passed by tumbling?

Metals, plastic, rubber, semi-precious stones, stones (gravel), etc. Basic tumbling technologies could replace expensive manual work in deburring, grinding, polishing, degreasing in better quality while removing the human error factor. Tumbling is used for processing semi-finished products of dental prostheses, titanium implants, polishing joint replacements, in jewelry for the production of jewelry, in hotels for washing and polishing cutlery.

Grinding, polishing and degreasing

For decorative object, the main requirement is appearance, for friction pins lower friction, for turbine blades of jet engines lower aerodynamic drag, for furniture fittings a thinner layer of metal during subsequent galvanic treatment, for gears lower friction, lower noise for bearings, etc.

Various lubricants are used in pressing, machining, forming, etc. Tumbling is ideal for combining two production operations - degreasing and grinding of parts. Tumbling can remove grease, rust, scale or unwanted discoloration from the surface after previous heat treatments.

Sanding with abrasive paste allows sanding and polishing to be combined into one operation. During tumbling, the rough surface is first sanded. As soon as the desired surface is reached by tumbling - grinding, the remnants of free abrasive are washed away from the tumbling bath and the grinding process is changed to a polishing process.
