Solving the problem of unstable size of CNC engraving machine Release time：2018-11-30
When the CNC engraving machine is in use, the size is unstable, so how can we solve this problem? The following crystal research technology professionals will explain to you how to solve the problem of unstable size of CNC engraving machine.

1. The connection between the servo motor shaft and the lead screw is loose, causing the lead screw pre-motor to step differently and present a dimensional error. It is only necessary to make a secret mark on the coupling of the servo motor and the lead screw during the test. Move the table (or tool holder) back and forth with a faster rate. Due to the inertia of the table (or turret), the two ends of the coupling will show a relative movement. This kind of obstruction is only a change to the processing size, but only a one-way transformation, just loosely tighten the coupling screw.

2. The rotating bearing is worn or improperly adjusted, resulting in excessive movement resistance. This obstruction phenomenon is also indicated as a change in the size of a few filaments. Simply change the worn bearing and correct it, and the obstacle can be removed.

3. The movement resistance of the machine tool table (or tool holder) is too large, which is generally caused by the tight adjustment of the strip and the poor lubrication of the machine guide rail. This obstruction is generally indicated by the fact that the part size cannot be changed within a few wire categories, and it is only necessary to adjust the strip from the head and improve the lubrication of the guide rail.

4. The lubrication between the ball screw and the nut is poor, so that the resistance of the table (or the tool holder) is increased, and the movement command cannot be completely accurately executed. This type of obstruction is usually indicated by the fact that the size of the part cannot be changed within a few lines, and the lubrication can be improved to remove the obstruction.
