surface improvement of skd61 die steel material after electrical discharge machining with graphite

Electrical Discharge Machining

Also known as spark machining, wire erosion, die sinking and spark eroding, EDM is a manufacturing process used to create desired shapes by using an electrical discharge of sparks. In this process, material is shaved, carved and otherwise removed from the workpiece through a series of rapidly repeating current discharges between two different electrodes.

Effect of Silicon Carbide Powder Mixed EDM on Machining

As we know the stainless steel material SS316L is very difficult to machining due to reasons such as having low thermal conductivity, high built up edge tendency and high corrosive resistance. Application of these materials is in various valve manufacturing industries, biomedical industries, pump industries manufacturing of various product prototypes, etc.

A Review of Additive Mixed

Surface treatment remained a key solution to numerous problems of synthetic hard tissues. The basic methods of implant surface modification include various physical and chemical deposition techniques. However, most of these techniques have several drawbacks such as excessive cost and surface cracks and require very high sintering temperature. Additive mixed-electric discharge machining (AM

Surface quality analysis of die steels in powder

The results show that the SKD11 steel surface after machining will have the largest SR, and the SR of SKD61 steel and SKT4 steel is equal (Figure 2(a)). The reason is that the melting temperature and evaporation of SKD11 steel (1370C) are lesser than those of SKD61 steel (1454C) and SKT4 steel (1510C), and the electrical resistivity of SKD11 steel is also lesser than SKD61 and SKT4.
