The spark machine is a kind of mechanical processing equipment, mainly used for electric discharge machining. It removes conductive materials through the electro-erosion effect generated by the pulse discharge between the two poles immersed in the working fluid. Therefore, it is mostly used in the manufacture of various metal molds and mechanical equipment. middle. At present, CNC spark machines and ZNC spark machines are more commonly used in the market. What is the difference between the two?
CNC EDM is a CNC machine tool with 3 or more axes. Each axis can be EDM, and it can also realize multi-axis linkage EDM; ZNC EDM can only EDM the Z axis, and the X and Y axes need to be manually processed. control. According to the current domestic production market, ZNC spark machines, that is, single-axis CNC machine tools, are mainly used. Its biggest feature is that it is cheap, suitable for a single workpiece, and generally used for parts with relatively simple shapes. However, with the development of the manufacturing industry, more and more electronic products have higher requirements in terms of appearance complexity and precision. Obviously, the ZNC spark machine has been unable to meet its production.
Compared with ZNC spark machine, CNC spark machine has absolute advantages in parts complexity and precision. Because it is a 3-axis linkage computer-controlled machine tool, it can realize the discharge function of 3-axis and 6 directions at the same time. It only needs to use the computer program to process the parts, so it is more convenient to process complex parts.
In terms of production efficiency, the ordinary ZNC spark machine has only one spindle to discharge, while the CNC has 3 spindles and 6 directions of discharge at the same time, and the processing efficiency is definitely higher than that of the ZNC spark machine. Theoretically, the CNC spark machine is 2-3 times more efficient than ZNC for processing the same product. In terms of production cost, ZNC spark machine has low cost, and it can be produced for most products on the market. The low price makes ZNC spark machine become the mainstream of the market. But from a long-term perspective, the benefits of CNC spark machines will become more and more prominent.
