needle coke hp 350mm graphite electrode

Compared with copper needle coke hp 350mm graphite electrode, needle coke hp 350mm graphite electrode has needle coke hp 350mm graphite electrode with low consumption, fast processing speed, good machinability, high processing accuracy, small thermal deformation, light weight, and easy surface treatment , High temperature resistance, high processing temperature and other advantages.

E and bondable needle coke hp 350mm graphite electrode. In order to meet the needs of processing simple shape needle coke hp 350mm graphite electrode, traditional turning, milling and grinding methods are usually used. However, in recent years, the requirements for the geometric complexity of the needle coke hp 350mm graphite electrode have continued to increase.

The high-speed machining surface quality and high machining accuracy make the high-speed machining of needle coke hp 350mm graphite electrode a hot spot in die EDM. Many needle coke hp 350mm graphite electrode manufacturers have introduced graphite high-speed machining centers.

In the subconscious understanding of graphite, graphite is generally regarded as a soft material. However, actual test data and applications show that the hardness of graphite is higher than that of metal materials. In the special graphite industry, the general hardness test standard is the Shore hardness test method, and its test principle is different from that of metals. Due to the layered structure of graphite, it has excellent cutting performance during the cutting process. The cutting force is only about 1/3 of that of copper materials, and the machined surface is easy to machine. However, due to its high hardness, tool wear will be slightly larger than metal cutting tools. At the same time, high hardness materials have a good control effect on discharge loss. In our company’s EDM material system, there are two types of materials with the same size to choose from, one with higher hardness and the other with lower hardness to meet different requirements of customers.
