Depending on the running speed of the electrode wire, EDM machine tools are generally divided into two categories: one is the high-speed Wire Cutting EDM Holes Machine, whose electrode wire reciprocates at high speed, and the general wire speed is 8-10m / s. The electrode wire can be reused and the processing speed is high, but fast wire walking is easy to cause the electrode wire to tremble and stop in the reverse direction, which reduces the processing quality. The other type is a low-speed wire-feed EDM wire cutting machine. The electrode wire is used for low-speed unidirectional movement. Generally, the wire speed is less than 0.2m / s. The electrode wire is no longer used after discharge. The quality is good, but the processing speed is low. It is the main machine produced and used abroad.

According to the different control forms of the electrode wire movement trajectory, EDM machine tools can be divided into three types:
One is by imitation shape control. Before the wire cutting process, a master mold with the same shape as the workpiece is manufactured in advance. During processing, the workpiece blank and the master mold are clamped on the machine table at the same time. During the cutting process, the electrode wire Move tightly against the edge of the master to make a trajectory, so as to cut out the workpiece with the same shape and accuracy as the master;
The other is photoelectric tracking control. Before wire cutting processing, firstly draw a photoelectric tracking chart according to a certain magnification according to the part drawing. During processing, the pattern is placed on the photoelectric tracking table of the machine tool. The head always follows the trajectory of the ink line graphics, and then, by means of electrical and mechanical linkage, controls the machine tool table and the workpiece to make similar movements relative to the electrode wire, so as to cut out the workpiece with the same shape as the pattern;
The other is digital program control, which uses advanced digital automatic control technology to drive the machine tool to automatically complete the processing according to the CNC machining program pre-programmed according to the geometric parameters of the workpiece before processing. There is no need to make a model template or draw an enlarged view. The first two control forms have higher machining accuracy and a wide range of applications. At present, more than 95% of EDM machine tools at home and abroad have adopted numerical control.
What are the current sales channels of wire cutting machine tools? This is a lot of users who want to buy wire cutting machine tools as soon as possible, especially want to know, the current utilization rate of wire cutting machine tools is relatively high, and the quality of the workpieces it processes are relatively high, so many people are willing to choose wire cutting machine tools Therefore, many users want to know about the common wire cutting machine tools. What are the channels for sale? Want to get a closer look and buy.
There are many common channels for selling EDM machine tools. For example, you can directly contact the High-Speed CNC Machine Tool Supplier, and each province, including counties, has such sales points. You can also order and purchase through the Internet. Because the current network is more developed, you can buy everything online, and wire cutting machine tools are no exception. So as long as you choose a website with a high reputation, you can buy a wire cutting machine the way of buying.
The use of wire cutting machine tools is very good. And the use of this machine tool is very good. Let us think that there is really a lot to know about the use of a device. Naturally, some problems are well contained.
