<p>Collets for handling and clamping workpieces having a circularly profiled clamping surface are described. Each collet consists of a chuck with clamping fingers forming a generally circular clamping surface which is moved into operative engagement with the surface of the article to be clamped. One or more grooves are provided in the clamping fingers in which elastomeric rings are received and in which the rings protrude from the grooves beyond the clamping surface. The elastomeric rings may be toroidal O-rings and the grooves be provided with bottoms having a rectangular section. Collets engageable with the respective articles by either outward or inward movement of the clamping surface are described.</p> |
