What are the advantages and processing scope of wire EDM?

The advantages of wire EDM are:
(1) It has the basic characteristics of EDM, and can cut without manufacturing tool electrodes;
(2) Narrow slits can be cut without any waste, so the utilization rate of materials can be improved;
(3) It can improve processing accuracy and reduce surface roughness;
(4) Its cutting efficiency is generally 20-60 mm2/min, and the highest can reach 300 mm2/min; the maximum cutting thickness can reach 600 mm.

The processing range of wire EDM is:
Mold processing: mainly refers to various small parts and narrow grooves with complex shapes, especially suitable for electrode processing of punching dies, extrusion dies, plastic molds and cavity molds.
New product trial production: directly cut parts to achieve the purpose of shortening the product development cycle and reducing costs.
Difficult-to-machine parts: mainly used for the processing of precision holes, templates and forming tools.
Cutting of precious metals: cutting precious metals can effectively reduce material consumption, thereby reducing processing costs.
