Common processing problems of CNC vertical lathes mainly include the following aspects:

1. Large or unstable workpiece size deviation: This may be due to accuracy issues with the machine tool and fixture, or improper setting of processing parameters. In order to solve this problem, CNC vertical lathes need to check the accuracy of the machine tool and fixture, and adjust the processing parameters to ensure the stability and accuracy of the processing.

2. Large processing surface roughness: CNC vertical lathe This is usually caused by factors such as unsharp tools, unreasonable cutting parameter settings or machine tool vibration. CNC vertical lathe solutions include adjusting the sharpness of the tool, optimizing cutting parameters, as well as checking the stability of the machine tool and performing necessary maintenance.

3. Short tool life: The short tool life of CNC vertical lathe may be caused by improper selection of tool materials, poor cutting conditions or excessive tool wear. In order to extend the life of CNC vertical lathe tools, appropriate tool materials and coatings should be selected, cutting temperature and cutting force should be controlled, and severely worn tools should be replaced in a timely manner.

4. Program errors lead to part processing errors: This may be due to errors or omissions in CNC vertical lathe programming, resulting in the processing program being inconsistent with the actual processing requirements. In order to avoid this problem, CNC vertical lathes need to strictly verify and test the program to ensure that the CNC vertical lathe programs are correct and repair any errors found in a timely manner.

5. Unstable operation of the machine tool: Unstable operation of the CNC vertical lathe may be caused by wear, looseness or poor lubrication of the machine tool components. In order to solve this problem, CNC vertical lathes need to check the wear and looseness of various parts of the machine tool, replace damaged parts in time, and keep the machine tool in good lubrication condition.

6. Machine tool resonance: CNC vertical lathe resonance may cause poor surface finish of the workpiece. This usually has to do with the stability of the machine tool, the firmness of the foundation, or tool selection. To solve this type of problem, you need to ensure that the CNC vertical lathe is placed on a stable foundation, reinforce it if necessary, and select appropriate tools to reduce resonance.

7. Spindle problem: The high-speed rotation of the CNC vertical lathe spindle may cause serious wear of the bearings, which in turn may cause changes in the processing dimensions. In order to solve this problem, CNC vertical lathes need to regularly check the wear of the spindle and bearings, replace seriously worn parts in time, and optimize the spindle speed and cutting parameters.

To sum up, solving common processing problems of CNC vertical lathes requires comprehensive consideration of multiple aspects, including machine tool accuracy, tool selection, cutting parameters, program verification, and machine tool maintenance. By taking appropriate measures and making necessary adjustments, CNC vertical lathes can effectively improve the processing quality and efficiency of CNC vertical lathes.
