Abstract
A process for the surface treatment of elastomers forming the outermost layer of a coated rotationally symmetrical body, the outer layer having a hardness of from 10 Shore A to 100 Shore D, wherein a high cycle motor spindle bearing a high-speed cutter head with cutting tips is brought into contact with the work material.
Claims6
A process for treating the surface of a rotationally symmetrical body, the surface to be treated comprising an elastomeric coating on the body, the coating having a hardness of from about 10 Shore A to about 100 Shore D, comprising the following steps:
- rotating the body around an axis of rotational symmetry,
- contacting the surface of the body with a high-speed cutter head mounted on a high cycle motor spindle, the high-speed cutter head having cutting tips, the cutting tips being made of hardened metal, and
- rotating the cutter head such that the surface is etched by the removal of chips of elastomer due to the contact between the tips and the surface.
