Trowalizing or vibratory cutting is a frequently used process, especially in metal processing. A workpiece is positioned in a drum together with loose abrasive grains. This sets the objects in relative motion so that material is removed. Several purposes can be achieved with trowalizing, including
- Deburring
- Rounding
- Polishing
- Matting
- Degrease
The abrasives used differ in their shape, size and material. The surface finish that can be achieved depends on the totality of these properties and the speed of their movement.
