The Function Of The Rotary Table Of CNC Milling Machine

The machining motion of CNC milling machine is a process of linear motion along the three coordinate axes of X, Y, and Z and rounded feed motion of X, Y, and Z axes. It has the characteristics of strong adaptability and flexibility, so it is used In various machining industries. With the increase in the complexity of the machining process of CNC milling machines, after installing a rotary table on the machine tool table, it is convenient to process various arcs and various box parts, which not only expands the processing range of CNC milling machines but also To a certain extent, the production efficiency is improved.
The appearance of the CNC milling machine after adding the rotary table is similar to that of the general machine tool table, and the internal structure has the characteristics of the feed drive structure of the CNC milling machine. The rotary table of the CNC milling machine with active tool change is a compensatory CNC reversing table, and its feed and positioning locking are controlled by given instructions. Under normal circumstances, the feed movement of the CNC milling machine is completed through the rotary table.
The rotary table of the CNC milling machine can not only perform various arc processing or linear feed linkage for surface processing, but also complete the indexing of the machining accuracy of the parts, which brings great convenience to the processing of box-type parts. For multi-process processing machine tools with active tool change, the rotary table is an indispensable component.
The movement of the rotary table is driven by the servo motor, which drives the table to rotate after being decelerated by the gear. In order to reduce the backlash and transmission clearance, the backlash of the gear is reduced by adjusting the eccentric ring.
