ABSTRACT:
A wire chopper module for processing spent electrode emerging from an EDM system employs replaceable inserts that are also movable relative to the feed path of the electrode. Shifting the position of the inserts relative to the feed path of the electrode allows more than one portion of each cutting edge on the insert to be used. Each insert has more than one cutting edge and can be rotated and re-inserted to present a completely new cutting edge. Removable multi-edge inserts that are repositionable relative to the feed path of the spent electrode permit renewal of the cutting edges of the wire chopper module with increased frequency and reduced cost. The wire chopper module also incorporates a flywheel to increase the moment of inertia of the rotating cutting inserts as an aid in overcoming jams. Sharp cutting edges and increased rotational momentum improve the reliability of the inventive wire chopper module.
