Using NC lathe skills to process workpieces will inevitably present a variety of faults. Today, CNC lathe manufacturers explain to you the problems of poor arc processing and inadequate scale. In the processing of workpiece, the arc effect is not ideal or the scale is not in place. There are various reasons, including resonance caused by overlapping oscillation frequencies; unsuitable processing technology; unreasonable parameter setting, excessive feed speed, resulting in arc processing out of step; abrasion of synchronous belt; loosening caused by excessive clearance of lead screw or excessive tightening of lead screw lead to out of step.

     To deal with the above problems, CNC lathe manufacturers recommend that you find resonance workpiece, change frequency, avoid resonance again; reconsider the processing technology, compile a reasonable program; step motor processing rate F can not be set too large; replace synchronous belt; determine the machine tool device is firm, stable, check whether the trailer is too tight, gap increases or tool holder. Loose and so on. Another problem is that the workpiece processing process changes, but the other process scale is accurate. The reason for this situation is that the program parameters are unreasonable, not in the scheduled orbit, and the pattern does not meet the requirements of the specification. Processing measures are relatively simple, check whether the thread program section presents random code, or the pitch is not right, and redesign this section of the program.
