Adjusting the spindle of CNC lathe equipment requires careful operation. The following are the general steps for adjusting the spindle of CNC lathe:

1. Preparation:

Before adjusting the spindle of a CNC lathe, ensure that the lathe is in a safe state, the spindle has stopped rotating, and the power supply is turned off.

Use appropriate safety gear such as gloves and goggles to ensure safe operation of CNC lathes.

2. Measure the geometric parameters of the spindle:

CNC lathes use appropriate measurement tools, such as oscilloscopes, laser interferometers or other measuring instruments, to measure the geometric parameters of the spindle, including axial, radial and angular errors.

3. Adjust axial error:

CNC lathes use axial oscilloscopes or other measuring instruments to detect the axial error of the spindle.

Based on the test results, the CNC lathe gradually reduces the axial error by adjusting the preload of the spindle bearing or other parameters.

4. Adjust radial error:

CNC lathes use radial oscilloscopes or other measuring instruments to detect the radial error of the spindle.

Based on the test results, the CNC lathe gradually reduces the radial error by adjusting the bearings of the spindle and grinding the surface of the spindle.

5. Adjust the angular error:

CNC lathes use angular oscilloscopes or other measuring instruments to detect the angular error of the spindle.

According to the test results, the angular error is gradually reduced by adjusting the installation position of the spindle and grinding the end face of the spindle.

6. Check the parallelism and perpendicularity of the spindle:

CNC lathes use parallelism and perpendicularity measuring instruments to check the parallelism and perpendicularity of the spindle and the workbench or other reference surfaces. Adjust as needed.

7. Check the spindle torque and speed:

The CNC lathe starts the spindle and checks the spindle torque and speed using a torque measuring instrument and a tachometer. Make sure they are within normal range.

8. Carry out processing test:

Run the CNC lathe and conduct some simple processing tests to check the size and surface quality of the workpiece to ensure that the spindle adjustment achieves the desired effect.

When performing these adjustment steps on a CNC lathe, caution is required and adjustments should be made according to the specific CNC lathe model and the manual provided by the manufacturer. If you are not sure how to adjust the spindle, it is recommended to consult the CNC lathe manufacturer or professional maintenance personnel for help.
