When customers use the CNC vertical machining center to realize processing, they often encounter unstable rail accuracy or other situations. At this time, they need to adjust the rail in time. During the entire calibration process, pay attention to three problems to effectively avoid the occurrence of the rail. s damage.
1) Consider the mechanical strength of the repair layer itself and the actual operating environment of the guide rail. Regarding the differences between the adopted standards, performance, and operating environment, when repairing, welding repairs and sticking repairs should be made according to the actual situation, and advanced correction methods and process methods should be used.
2) Consider whether the selection process has an impact on the accuracy and mechanical properties of the guide rail. If it is affected by temperature, whether it will cause the guide rail to deform, whether it will change the mechanical strength and surface hardness of the guide rail.
3) Consider the selected calibration process and the suitability of the guide rail material.
The perpendicularity and parallelism between the guide rails and the straightness of the guide rail in the plane will affect the geometric accuracy of the CNC vertical machining center. The guide rail accuracy is also more complicated. The physical properties, structure, and craft materials will all determine the guide rail accuracy. .
The influence of horizontal accuracy on CNC vertical machining center can be summarized into the following three points:
1. If the level does not reach the specified range, the CNC vertical machining center will cause the deformation of the guide rail during long-term work, and the verticality of the X and Y axes will also be affected.
2. After the guide rail is deformed, the worktable will also be deformed. In this situation, the verticality of the spindle and the worktable will also become worse, and the result will affect the plane machining accuracy of the CNC vertical machining center.
3. The overall service life of the guide screw and the CNC vertical machining center will be reduced.
