Abstract
An EDM machine in combination with a wire sectioning device. The wire sectioning device has two rotating members consisting of a rotating member 2 having an anvil 16 and a member 3 rotating in the opposite direction. The rotating member 3 has four cutting blades made of a tough material such as tungsten carbide or tungsten nitride. At least one of the anvil and the tool possesses a low moment of inertia to improve the longevity of the sectioning means.
Claims24
A combination for providing numerous cut sections of an EDM machining wire, comprising:
- an EDM machine apparatus;
- an electrode wire evacuated by said EDM machining apparatus at a linear speed;
- and
- means for sectioning said evacuated wire into numerous cut sections, comprising:
- rotating hub having an axis of rotation;
- a rotating core having an axis of rotation parallel to the axis of rotation of said hub;
- an anvil disposed about and rotating with said hub;
- a tool disposed about and rotating with said core;
- at least one blade borne on said tool having a cutting edge disposed parallel to the axes of rotation of said hub and said core;
- and
- means for radially elastically mounting at least one of said anvil and said tool to a respective one of said hub and said core comprising a radially elastic support rotting with said respective one of said hub and said core, surrounding said axis of rotation of said respective one of said hub and said core;
- wherein said wire is located so as to translate between said anvil and said tool;
- and
- wherein said at least one of said anvil and said tool possesses a low moment of inertia, thereby both lessening the effect of acceleration experienced during impact of said blade against said anvil and improving the longevity of said sectioning means.
