CNC210 Operating Manual
Between small carriage and the carriage, carriage and bed ,the sliding surface are used angle
plug iron, the plug iron inclination to 1:100. Inclined plane with the surface after distribution
scraping, and ensure good contact, when the gap is bigger, you can use the screws at the ends of
the gradual adjustment of the position of the plug iron to adjust the size of the gap. After
adjustment the ends of the two screws should contact with the plug iron, in order to ensure the
plug iron rigid.Adjustment should be in a moderate gap, not only to meet the accuracy
requirements of the machine tool, see precision test list , but also flexible sliding. Friction is too
large, although the detection accuracy is good, but it will lead to wear too fast.
