Abstract
Device for machining contours (2) made of a soft material, such as plastic, and essentially including a rotary tool (6) constituted by abrasive elastic plates (5) whose flexibility makes it possible to dampen the jerks of the member (33) bearing the tool (6). Preferably, a pneumatic motor (9) and a speedometer (10) are used to automatically control the tool (6) at a constant speed guaranteeing a stable machining or cutting force. The method for the automatic machining of flexible burrs on a contour formed of a soft material, is also described.
