Product Description

This WEDM machine is composed of main engine, electric control system, software and cooling and filtering system. This equipment is used for the discharge machining of the track cutting of various complex dies and parts. It is used for the processing of various non-ferrous metals, tool steels, alloy steels and other materials. The main machine of the equipment should ensure high geometric accuracy and position accuracy, and have enough static, dynamic, thermal stiffness and accuracy. The equipment has the functions of taper cutting, taper-changing and abnormal meshing cutting.
