The spark machine is also a device, mainly for EDM machining of some molds, because its work efficiency is relatively high and the effect is relatively good, so it is suitable for various metal materials. But it is also divided into several kinds, and the use of each spark machine is not the same.

In fact, spark machining is mainly used for machining holes and cavities with complex shapes, molds and parts; processing hard alloy, hardened steel and other hard and brittle materials; processing deep holes, fine holes, special holes, deep grooves, narrow grooves and cutting thin plates;

there are several types of spark machine:

1. The fine-hole discharge motor is also an electric spark machine, its main purpose is stamping, that is, punching holes in the mold.

2. Mirror spark machine is a kind of spark machine that can deal with mirror effect. The processed mold can be directly used for production without saving the mold. Save manpower and improve efficiency. In addition, the mirror spark machine has high precision, especially in the application of precision molds. The cost of imported mirror spark machines is high, lower than 7.8 million yuan and lower than 0.497 billion yuan. The rapid development of domestic mirror spark machines in recent years has exceeded the advanced level of foreign countries.

3. Plastic processing machine is a common spark machine, mainly for plastic mold processing, is very common in our country, and the price is not expensive, and the use is relatively wide.

4. CNC machine, three-axis CNC machine, CNC spark machine with automatic model, automatic centering, automatic programming, G code programming, three-axis linkage discharge and other functions.

5. There are also some special machines, such as machines for playing graphite and tungsten steel.
