cnc high-speed vertical lathe on sales introduces what factors determine the accuracy of vertical lathes
Do you know what factors determine the accuracy of a vertical lathe? Follow the cnc high-speed vertical lathe on sales editor to have a simple understanding!
1. Geometric accuracy
The geometric accuracy of the machine tool is the basic condition to ensure the machining accuracy. The geometric accuracy of the CNC machine tool reflects the geometric error of the key mechanical parts of the machine tool (such as the bed, saddle, column, headstock, etc.) and the geometric error after assembly, including the flatness of the worktable and the mutual perpendicularity of the movement of each coordinate direction , The movement parallelism of the X and Y coordinate directions of the worktable surface, the radial circle runout of the spindle hole, the movement of the spindle axis, the parallelism of the worktable surface, the spindle when the spindle box moves in the direction of the z coordinate axis, and the spindle moves in the direction of the z coordinate axis. The straightness of the spindle and the perpendicularity of the spindle rotation axis to the table surface, etc.
2. Transmission accuracy
The transmission accuracy of a vertical machining center refers to the relative movement accuracy between the two ends of the relevant transmission chain in the machine tool. In the transmission chain between the spindle and the tool post, there are errors in gears, screws, and bearings, which make the actual distance of the tool post and the required distance error. This error will directly cause the pitch error of the workpiece. In order to ensure the machining accuracy of the workpiece, not only the machine tool is required to have the necessary geometric accuracy, but the inner chain transmission chain also requires higher transmission accuracy.
3. Positioning accuracy
The positioning accuracy of a vertical machining center refers to the error between the arriving position of the moving part and the expected position under the control of the numerical control system. The accuracy is the same as the geometric accuracy of the machine tool, which will have an important impact on the cutting accuracy of the machine tool, especially the hole pitch error during hole machining.
