The multi-cutting function of machine tool in CNC Machining Center can improve the accuracy and Ra of workpiece. The control system of CNC Machining Center can automatically adjust the processing parameters according to programming, such as high frequency pulse width, pulse interval, number of power tubes and wire speed. At the same time, it can also manually modify the processing parameters to achieve satisfactory results. But in the process of processing, CNC Machining Center machine tools sometimes have various problems, such as wire breakage, filament, workpiece cutting surface with commutation stripes, etc. These can not be solved by the control system of CNC Machining Center, but also need to be adjusted by human operation, so let’s talk about how to eliminate the commutation stripes on the cutting surface.
Firstly, the causes of commutation fringes in CNC Machining Center are as follows:
1. The pulling force of molybdenum wire in the reciprocating direction is not uniform.
2. The wear of guide wheel and bearing has not been replaced in time.
3. The quality of molybdenum wire, guide wheel and bearing is not good.
With these reasons, we can solve this problem.
First, check the tightness of molybdenum wire before processing in CNC Machining Center, especially when tightening wire, make it uniform, and adjust the tightness of molybdenum wire according to the situation in the processing.
Second if the guide wheel and bearing are badly worn, it is better to buy the original spare parts. In this way, there will be no mismatch between parts and machine tools, nor will it affect the processing effect.
