1. Improve the rotation accuracy of CNC machine tool bearings
When improving the accuracy of the rotation, you can choose high -precision rolling bearing, multi -oil to move the bearing, and static pressure bearing. At the same time, improve the accuracy of bearing accessories, such as improving the processing accuracy of the box support holes and the spindle axle, so that the spindle rotation accuracy is not reflected on the workpiece.
Second, control the heat deformation of the process
The CNC processing center is a high -speed cutting process. A large amount of heat will occur during the processing process. It should reduce the heat sources of heat sources and add the heat treatment process of eliminating the internal stress; The lower the processing accuracy, the higher the less processing accuracy.
Third, reduce the principle of less transmission chain transmission over the transmission system, the principle of small transmission parts, short transmission chain, and high transmission accuracy. Using speed reduction transmission is an important method to ensure the accuracy of the transmission.
Fourth, reduce the degree of wear of the CNC machine tool. Before the tool is worn sharply, we should wear the tool from the head, and select the special cutting oil for full lubrication. The tool material should meet the process requirements.
