There are three control methods for CNC wire cutting machine tools, namely: profiling control, photoelectric tracking control and digital program control, among which:

  1.Photoelectric tracking control: Before wire cutting, the pattern is placed on the photoelectric tracking table of the machine tool during processing, and then the machine tool table and the workpiece are controlled to make similar movements relative to the electrode wire by means of electromechanical linkage, and then the same shape as the pattern is cut. workpiece.

  2.Copying control: Before wire cutting, the workpiece blank and the mold are clamped on the machine table at the same time. During the cutting process, the electrode wire is close to the edge of the mold to make orbital motion, and then the workpiece with the same shape and precision as the mold is cut.

  3.Digital program control, using advanced digital automatic control skills, does not need to make templates or enlarge drawings, and has higher processing accuracy and wider application scale than the previous two control forms.

  Smoothing and cleaning should not be neglected in the application of linear cuts.

  Wire cutting has a beautiful appearance and a reasonable and compact structure. It is mainly used to process complex cavities and curved surfaces of various conductors such as various molds and fine parts manufacturing, which has a very important impact on the operation of later equipment.

  1.The smoothing work of the wire cutting machine includes the smoothing of the following components, during this period:

  1)Wire feed gear: should always be smooth and noise-free, otherwise it will shorten the service life.

  2)Wire screw: Refuel before starting work every day, there can be no harsh noise, otherwise it will simply accelerate the wear of the screw.

  2.For the cleaning of wire cutting machine tools, the machine tools should be wiped clean every day before get off work, and the unusable waste, rags, and waste molybdenum wire slag should be sorted out.

  When it comes to maintenance, if the wire cutting is not used frequently, some parts inside will rust and break. When using it, we should also pay attention to the temperature of the machine. The machine cannot be separated from the careful protection and maintenance of the user, which requires the user to operate it in practice. During the process, pay close attention to the running status of the wire cutting machine, and deal with the abnormality immediately.
