Abstract
A chuck used to attach an electrode to a CNC machine or an EDM machine having a quick release mechanism.
Claims19
A chuck, comprising:
- (a) a body having a mounting surface and defining a longitudinal bore extending into the body through the mounting surface;
- (b) a draw bar configured and arranged for longitudinal slidable engagement within the bore as between a machining position and a release position;
- (c) a release mechanism in physical communication with the bore whereby activating the release mechanism is effective for moving the draw bar from the machining position to the release position;
- and
- (d) at least three longitudinally extending parallel pins extending outward from the mounting surface and forming an asymmetric pattern about the longitudinal bore.

A chuck, comprising:
- (a) a body having a mounting surface and defining a longitudinally extending bore through the mounting surface;
- (b) a draw bar configured and arranged for longitudinal slidable engagement within the bore as between a machining position and a release position;
- (c) a release mechanism coupled to the body and in communication with the bore for movement between a first position and a second position wherein the release mechanism is effective for longitudinally lifting the draw bar from the machining position to the release position when the release mechanism is moved from the first position to the second position, and;
- (d) at least three longitudinally extending parallel pins extending outward from the mounting surface.
