We must use the wire-cutting machine to learn how to thread the wire. Then we should pay attention to what aspects we should pay attention to during the threading process. Next, let me talk about the following points when we take the wire in the wire.

One is the imitating control, which pre-manufactures the same mold with the shape of the workpiece before the wire cutting process. During the machining, the workpiece blank and the mold are simultaneously clamped on the workbench of the machine tool. During the cutting process, the wire electrode is Tightly close to the edge of the mold to make a trajectory movement to cut the workpiece with the same shape and accuracy as the * mold;

In the above method, the workpiece must be clamped, and adjustments must be made in conjunction with the method of alignment so that the positioning reference plane of the workpiece can be kept parallel to the feed direction x and y of the table and the table of the machine, respectively, to ensure that the surface and the reference are cut. The relative position accuracy between faces. The commonly used methods of correction are:

Wire-cutting machine tool operation processing techniques: In order to create a man-made environment and conditions to meet the conductive requirements, that is, when the staff in the operation of the electric discharge wire cutting machine encounters instructions MOO cut the remaining parts of the workpiece, can be used in the cut part and the mother The method of processing the adhesive copper and the plug copper in the cutting gap to cause the man-made positioning conditions and conductive conditions, so that spark machining can be continued, its specific practices and techniques are as follows: First, in the part of the cut and the parent material Paste connection copper sheet. The purpose is to make the remaining parts of the workpiece connect with the parent material during cutting to ensure that the wire cutting has good positioning conditions so as to guarantee the workpiece with excellent processing quality. This can be done according to the following steps.

In manufacturing, EDM and high-speed milling are key processes for making molds. Both processes compete and complement each other. In the past ten years, with the continuous development of super-hard tools, drive technology, machine tools and control technology, high-speed milling and EDM technology have been widely applied in manufacturing. Therefore, EDM technology also determines the cost of mold manufacturing.

China's wire-cutting machine tools originated in the early 1970s. Before the implementation of the market economy, the development of wire-cutting machine tools was relatively slow, mainly because China’s electronics industry was relatively backward, and the production lines of wire-cutting machine tools were all state-owned enterprises. Strong ability, but due to the disconnection from the market, combined with the constraints of the planned economy, the WEDM machine not only has a high failure rate, but also has limited performance (only 50mm thickness can be cut, and the efficiency is 20~30mm2/min) but anyway Wire-cutting machine tools are unique to China's machine tools. Compared with wire-cutting machine tools from abroad, wire-cutting machine tools are less precise, but their manufacturing and operating costs are absolutely superior. They are very suitable for those developing countries. Due to the demand of this potential market, after the implementation of the market economy in China, a large number of wire-cutting machine tool manufacturers have emerged across the country. As a result, disorderly competition has emerged in the wire-cut market, and disorderly competition has evolved into price competition. In order to reduce costs, Some enterprises with poor technical skills have lowered their production standards, and the related technical supervision agencies of the country have not managed Force, the quality of the EDM different manufacturers on the market a huge discrepancy.

Wire cutting machine guide wheel life - the life of the guide wheel is not calculated according to time, depends on what kind of material you process, as well as the quality of cutting fluid, better than bad can be judged by inspection .

Choose a place where the temperature changes little, and avoid sunlight passing through the window and top window glass and near the heat flow. High-precision parts processing products need to be carried out at a constant temperature, usually 20C at room temperature. Since the wire cutting discharge machine itself generates a considerable amount of heat during operation, if the temperature change is too large, the service life of the machine may be seriously affected.
