Centerless grinding machine is in use process, feed is no more headache, now the domestic traditional ordinary ordinary screw centerless grinder are mostly used for feed drive, because the screw have clearance, will lead to a direct feed will surely and actual feed value discrepancy, high-precision centerless grinding machine due to the ball screw, the error will be smaller. This needs us in feed back three times, and then into three times, eliminate clearance error, if still feed, we need to carefully examine the:

1, see if screw brake wheel lock. If can't lock, can resist inside two screw tap the wheel brake pin out, check the reshipment. If the skateboard feed, to check all the rest have left or right touched off the workpiece to resist, such problem can appear sometimes, need to check.

2, for Taiwan centerless grinding machine type, as a result of the feed from the lower right corner, check the feed the handwheel adjustment screw and the check out on the feed screw with or without screw loosening or excessive clearance are rolled back feed hand wheel much circle feel hand wheel clearance is too large, or feed when the hand wheel rotation is too tight, etc.

3, fine-tuning the feed tube position offset or loose, will cause the slide friction helical gear with adjustable screw clearance is too large. Or dense nuts too tight to cause rotation is not flexible, usually loose nut also causes this phenomenon is not allowed feed.

4, fine-tuning hand wheel and screw differential disk drive screw inside a fixed screw, also want to make sure no loose, fine tuning screw and screw with palin bearing also want to make sure there is no wear and tear or clearance is too large.

This question is simple, as long as careful inspection or removed cleaning reinstall can gradually eliminate, for wear light, can be properly tightened, but for the poor quality of low-end, badly worn parts, will need to be replaced.
