The positioning accuracy of the machine tool has an important impact on the accuracy of the parts, and the core components that affect the positioning accuracy of the machine tool, such as the true straightness and horizontal degree of the system, guide rail, workbench, etc. When designing CNC machine tools, the core components should be selected reasonably. For example, when selecting the roller screws widely used in the current machine, the accuracy of the roller screw should be fully considered, and the relatively mature roller screw technology should be selected and installed. The support of the roller screw must not be ignored. The support of the roller screw is closely related to the transmission accuracy of the system. And support method. At the same time, in the design process, strictly related inspections should be performed in response to the bearing capacity of the screw of the beads.
The drag chain, as part of the protection of the machine tool, is now indispensable for machine tools. Due to its chain structure, a certain vibration will occur when following the knife rack movement. This vibration will be passed directly to the tool, and Z will eventually affect the processing accuracy.
