Testing precision CNC lathes is a key step to ensure their performance and machining accuracy. The following are the general steps for testing precision CNC lathes:

1. Machine tool geometric accuracy detection:

CNC lathes use straightness measuring instruments, parallelism meters, perpendicularity meters and other tools to detect the straightness, parallelism and perpendicularity of each axis of the CNC lathe. Ensure that the axis movement is smooth and the parallelism and verticality between the axes meet the requirements.

2. Position accuracy detection:

CNC lathes evaluate the positioning accuracy and repeatability accuracy of CNC lathes by measuring the deviation between the actual processing position and the programmed position of the workpiece at different positions.

3. Roundness and cylindricity detection:

CNC lathes use measuring tools such as micrometers and outer diameter measuring instruments to detect the roundness and cylindricity of the processed cylindrical surface.

4. Surface roughness detection:

CNC lathes use surface roughness measuring instruments to measure the processed surface to ensure that its surface quality meets the requirements.

5. Tool deviation detection:

CNC lathes detect the geometric parameters of the tool, including tool tip arc radius, tool tip angle, etc., to ensure that the tool geometry meets the design requirements.

6. Dynamic performance testing:

CNC lathes conduct dynamic performance tests such as rapid movement, emergency stop, acceleration and deceleration, etc. to ensure that the response speed and dynamic performance of the CNC system meet the requirements.

7. Spindle performance testing:

Detect the speed and torque of CNC lathe spindle to ensure stable spindle performance under different working conditions.

8. Processing test:

Run the CNC lathe CNC program, conduct processing tests on some typical workpieces, and measure the size and geometric tolerances of the workpieces to evaluate the processing capabilities and accuracy of the CNC lathe.

9. CNC system parameter detection:

Check the parameter settings of the CNC system, including cutting speed, feed speed, acceleration, etc., to ensure that they match the processing requirements.

10. Temperature stability testing:

CNC lathes test the stability of CNC lathes under different ambient temperatures to ensure that they can maintain stable processing performance under different temperature conditions.

When performing these inspections on a CNC lathe, it must be operated according to the model of the CNC lathe and the technical specifications and operating manual provided by the manufacturer. If you are unsure about anything, it is recommended to consult the CNC lathe manufacturer or professional maintenance personnel for help.
