In order to process EDM products with high dimensional accuracy and good appearance, it is necessary to carefully consider the workpiece materials used:

  (1)Due to the different workpiece materials, the surface quality of the obtained workpieces is also different. Carbide material must be selected instead of stainless steel or unhardened high carbon steel, otherwise it is difficult to meet the requirements.

  (2) Because the internal residual stress of the workpiece material has a greater influence on the machining, because the removal of metal in a large area and the blocking process will destroy the relative balance of the residual stress in the material, which may affect the machining accuracy and appearance quality.

  (3) Various parameters should be adjusted to the best state during wire cutting to reduce wire breakage. If there is a broken wire, it will definitely go back to the starting point and start over from scratch. In the process of processing, you should also pay attention to the sound of the machine tool. The pointer of the ammeter and the voltmeter of the machine tool should have a small amplitude, and the feed rate is uniform and smooth at this time.

  There are many factors that affect the appearance quality of wire cutting workpieces, but as long as they are systematically analyzed and scientifically classified, these chaotic factors can be controlled and deployed, and then the appearance quality of workpieces can be improved and improved.

  Tiangong Machine Tool Manufacturing (Changxing) Co., Ltd. is mainly engaged in surface grinder, wire cutting production, and wire EDM machine manufacturing and sales. Strong design and development, manufacturing, installation and commissioning, technical maintenance, irregular return visits, strict quality assurance and fast after-sales service, each link has been carefully arranged to solve a series of worries of customers.
