Wire EDM

Wire EDM is abbreviation of Wire Electrical Discharge Machining. It’s to use movable metal wire (molybdenum wire, copper wire or alloy wire) as electrode wire.
The pulse current spark discharges in the electrode wires, then generates high temperature to melt or vaporize the metal to form a gap, so as to cut out parts.

Advantages and Features

01  Suitable for complex shapes that are difficult to produce with traditional cutting tools.

02  A good method to do trial production for new products with short run.

03  Work well to process hard conductive materials.

04  Suitable for cutting precious metals. Can reduce the loss of slitting, thus reducing costs.
