During the entire cutting process of CNC machine tools, the cutting tools and workpieces installed on ordinary machine tools will move relative to each other according to certain rules. The excess metal is cut off by the cutting action of the blade on the workpiece blank. Cut it away to get the surface shape we need. The editor below will take you to understand the three major movement steps of CNC machine tools.
Commonly used surface shapes in workpieces include: plane, cylinder, cone, sphere, ring and other surface elements. In order to process various curved surfaces, the following relative motion must be maintained between the tool and the workpiece of ordinary machine tools.
1. The workpiece rotation movement (main movement) is the basic movement process required for cutting processing, and it is also a fast and high-power consumption movement. Mainly n (n/min).
2. The tool movement (feed movement) is relatively slow and the power consumption is relatively small. Mainly expressed by F (mm/R).
3. The main motion and feed motion required to form the surface shape of an ordinary lathe to be processed are called the forming motion of an ordinary lathe. Ordinary lathes of machine tool equipment companies
are composed of spindle box, bed, feed box, slide box, tool rest, tailstock, etc. The overall layout, appearance, transmission system structure, and operating mechanism of ordinary machine tools are the same as before, and in this case Mainly to meet the needs of ordinary machine tools and allow them to perform normally.
Generally speaking, what we call CNC machine tool spindle bearings, ball screw bearings, and precision machine tool bearings refer to spindle bearings and screw bearings with an accuracy of P5 and above.
The requirements for rolling bearings used in universal transmission bearings for CNC machine tools are the same as those for universal mechanical transmission bearings, as long as they meet the requirements for strength and service life, and the rotational speed does not exceed the specified limit rotational speed.
