Wire cutting arrangement for electroerosion machine

摘要

The wire cutter has a cutting wheel (58) with teeth (59) co-operating with a counter cutter (60) having an axial bore extending across which the wire is fed towards the cutting wheel. The counter cutter is cylindrical with a recess (65) in the surface to reduce the wearing contact surface with the counter cutter support and allow easier rotation of the counter cutter by the cutting wheel.
