Through years of use and practical experience, I have done some research on the faults that often occur in CNC wire-cutting machines and the elimination. Faults and exclusions caused by the main components of the machine tool The installation of CNC wire-cutting machine tools is higher than that of ordinary machine tools. First of all, it is necessary to ensure good insulation between the components. For example, the ground wire of the bed and the ground wire of the control cabinet cannot be directly connected; the workpiece and the wire frame are insulated from the machine tool, the guide wheel and the wire frame. If the insulation performance is poor, it will be processed. The process brings hidden faults. When the wire frame and the guide wheel and the bed are poorly insulated, the guide wheel will have current passing through it to easily damage its bearing; when the control cabinet and the bed are poorly insulated, the high-frequency current can pass through the bed and enter the bearing of the storage tube. Damage, at the same time can also cause instability in the process, the phenomenon of multiple wire, which is generally not easy to find in the empty stroke. In order to solve this situation, the best way to eliminate the insulation is to improve the insulation, and connect a resistance of 500KΨ or more between the neutral line of the stepping motor and the ground of the machine tool. After many tests, you can receive a good effect. The cylinder should run smoothly and there should be no abnormal vibration and shaft cranking. The screw pair of the transmission part adopts a double nut structure, the double nut must be tightened, and at the same time, it must be lubricated according to the requirement of lubrication “five fixedâ€. Once the spiral gap is large, the wire reeling will cause a double-fold phenomenon, causing loose yarn, which will affect the processing quality. If vibration occurs during operation, abnormal noise will be generated. Generally, the rolling bearing at both ends of the winding drum will be produced. Looseness or the loosening of the key of the coupling between the motor and the wire cartridge causes noise and should be repaired in time. The wire is stretched as much as possible within its elastic deformation limit. If the tension is too small, the rigidity of the wire will be insufficient, and the vibration will increase, which will affect the dimensional accuracy and roughness of the workpiece. If the tension is too large, the wire will be broken. The working medium coolant during the electrolytic etching process has a direct influence on the pulse discharge process, so the machine must ensure sufficient coolant during the working process. When the amount of electrolytic corrosion products in the coolant increases, a short circuit is caused during the processing to cause the wire to be broken, so the coolant must be replaced after it is dirty.
