Clamping chuck for fitting to a device for polishing lenses with a grip holder has gripping jaws for holding a body to be polished and a clamping head with limited movement on a tool shank

摘要

A piston (30) can be guided in a cylinder (31) as far as the bottom of the cylinder. Force applied to a slide rod from beneath is transferred onto a clamping piston (22) to move it upwards by compressing a disk spring package. Up to 6 bar air pressure is applied into the cylinder above the piston through a longitudinal drilled hole (40) in a slide rod. A clamping head is held on a tool shank with restricted movement. An Independent claim is also included for a device for polishing a lens with a clamping chuck.
