What is EDM and WEDM?

WEDM and EDM can be used to machine superhard materials and complex shaped workpieces that are difficult to machine by conventional cutting methods. They are often used to machine electrically conductive materials and can machine complex cavities or contours in difficult to machine materials such as titanium alloys, tool steels, carbon steels and hard alloys.

Materials used: 1.2343/1.2344,1.3343,H13,ASP23,ASP60,tungsten carbide,hardened tool steel,Inconel、Titanium、Hactelloy、Super Invar、Nickel.


EDM is based on electrode etching machining and WEDM is based on copper wire cutting machining.

Generally machined steel because of the electrical conductivity.

WEDM is capable of reaching the 0.002 range and EDM the 0.005 range.

We need 3D files for quotation and programming.

EDM & WEDM Types

Micro-Hole EDM

Minimum 0.006 holes can be completed


Suitable for all responsible shapes of workpieces


Suitable for cutting straight shapes to an accuracy of 0.002


X- and Y-axis linkage for sparking machine cutting is possible

SPP Industry Ltd.

In the 1990s, SPP Industry Ltd was one of the first manufacturers to establish CNC machining in China. The company has now established five major machine parks in China, with significant achievements in the areas of 5-axis machining, precision grinding & honing, gear machining, large parts machining, custom tungsten carbide and new material development respectively.
