ZNC Sinking EDM

EDM540ZNC

Product in details

Jingzhou Mind Science and Technology Co.,Ltd.

Main Application

EDM sinker machine is used for cavity forming. It utilizes conductive material (copper, graphite, steel) as electrode to process workpiece (conductive material) by spark erosion. Main use: processing precious die, cavity mold and so on. It is widely used in metal processing and mold making workshop.

Jingzhou Mind Science and Technology Co.,Ltd.
