Concentric chuck for turning-machines

摘要: Abstract not available for EP0250724Abstract of corresponding document: US4771933The chuck clamps a workpiece on clamping axis eccentric to the rotation chuck. The spacing between and parallel it can be varied along radial line going through axis. One jaw has surface which intersects plane perpendicular is adjustable line. other jaws opposite this one are adjustably mounted in guides inclined symmetrically about jointly centrally drivable. first both independently each other. Each planar its guide direction. does participate process exists change spacing. It formed as revolving disk rotatably body with axis, drivable stepwise direction fixed plurality different rotary positions. A surfaces located at several places circumference from These correlated allowed positions so that positioned guided position.
