CNC vertical lathe is a precision machining method in the field of modern machining. It can provide highly precise axial machining to meet the requirements of machine parts processing needs. However, there are still some accuracy problems during the processing of CNC vertical lathes. How to improve the processing accuracy has become an important problem faced by manufacturers. In this article, we will explore ways to improve the accuracy of CNC vertical lathes.
1. Improve processing rigidity
In CNC machining, the higher the machining stiffness, the higher the machining accuracy will be. Methods to improve stiffness include increasing the stiffness of materials, optimizing cutting tool design, etc. For high-rigidity processing parts, CNC vertical lathes need to use more sophisticated processing tools to obtain higher precision. In addition, composite processing can also be used to improve stiffness.
2. Improve lubrication and cooling
Lubrication and cooling are inevitable problems in the CNC vertical turning process. During the processing of CNC vertical lathes, lubricants and coolants can effectively reduce the thermal deformation and cooling stress of the workpiece and improve the processing accuracy. In addition, lubrication and cooling reduce frictional resistance and reduce tool and workpiece wear. Therefore, during the CNC vertical turning process, the lubrication and cooling systems should be optimized to ensure their normal operation.
3. Optimize tool design
In CNC vertical lathes, the design of the tool directly affects the processing accuracy. Factors such as the shape, material, surface coating, and angle of the tool all have an important impact on the machining accuracy, so optimal design is required. The sharp angle of the tool is directly related to the surface quality. Note that the sharp angle of the tool should not be too large. At the same time, using better tool coatings can protect the tool surface, reduce wear, and improve cutting efficiency and processing accuracy.
4. Improve the accuracy of CNC system
Improving the accuracy of the CNC system can enable CNC vertical lathes to achieve higher processing accuracy and higher work efficiency. The accuracy of a CNC system depends on the accuracy of the controller, drive, encoder and feedback. For CNC vertical lathes, the control system needs to use high-precision encoders to obtain higher position accuracy. The drive and feedback systems need to use better regulators to improve drive accuracy. In addition, the controller and programming methods also have an impact on the machining accuracy, and attention needs to be paid to optimizing the parameter settings and programming methods of the system controller.
Improving the machining accuracy of CNC vertical lathes requires not only optimizing the machining stiffness, lubrication and cooling systems, but also optimizing the tool design and the accuracy of the CNC system. By adopting the above method, higher machining accuracy and higher work efficiency can be achieved during the CNC vertical lathe process, meeting the accuracy and requirements of machine parts processing.
