CNC centerless grinder in the operation of the situation is not allowed to enter the situation is due to the traditional domestic centerless centerless grinding machine mostly use the ordinary screw as the feed drive, because the screw gap, it will lead to direct infeed will certainly and the actual The infeed value does not match. The high precision centerless grinder due to the use of ball screw, the error will be much smaller. This requires us to go back in the three laps, and then into the three laps, to eliminate the gap generated by the error, if the knife is not allowed, we need to proceed to the next step. In the case of．
1) If the screw brake wheel is locked, if it can not be locked, it may be inside the top of the screw brake pulley taps two pins out, to check the reload. , To check the left or right side of the knife frame has not encountered the fall of the workpiece to withstand, this problem sometimes appears, need to check. (High-precision centerless grinding machine to accelerate the development of aerospace industry)
2) For CNC centerless grinding machine models, because it is from the lower right corner of the feed, should check the feed hand wheel fine-tuning of the fixed screw and the screw on the feed screw on the loose or loose or too large, back and forth into the knife Round multi-circle feel the gap is too large hand wheel, or into the hand wheel rotation is too tight and so on．
3) under the fine adjustment of the inlet tube position offset or loose, will lead to lower sliding plate friction screw gear and screw gap is too large. Or tight nuts caused by tight rotation is not flexible, under normal circumstances loose nuts can also cause this knife is not allowed to phenomenon.
4) hand wheel fine-tuning and screw differential plate inside the drive screw has a fixed screw, but also to determine no loosening, fine-tuning screw and screw above the Pui-lin bearing also to determine no wear or gap is too large.
These problems are better handled, you need to carefully check or remove the cleaning and re-installation can be troubleshooting treatment, for the slight wear and tear, can be properly tightened, wear parts need to be replaced, and try to use high-quality Parts, you can improve the accuracy of the grinding machine feed.
