How to solve the gap caused by NC machine tool?

How to solve the gap caused by NC machine tool? The following CNC lathe manufacturer will answer for you.

1、 Causes of NC machine tool clearance:

1. There is a gap between the ball screw and the nut pair of the machine tool, which can not be in close contact, resulting in shaft movement.

2. With the use of machine tools, wear gradually intensifies, resulting in clearance.

2、 What is the effect of NC machine tool clearance:

1. When the worktable moves in the reverse direction, the motor idles and the worktable does not move, resulting in a positioning error of ± D / 2 and affecting the accuracy of the machine tool

2. When the gap is too large, the dynamic response characteristics become worse and oscillate

3、 How to better solve:

1. High precision ball screw is adopted

2. Pre tighten the lead screw when installing it

3. Compensating gap with NC system command
