The CNC rotary table is an important part of CNC machine tools and has the following functions and effects:

1. Carrier clamping: The CNC rotary table can be used to clamp the workpiece, fix it on the worktable, and ensure the stability of the workpiece during processing.

2. Rotational motion: The CNC rotary table can realize rotational motion through the control system, so that the workpiece rotates in the horizontal direction. This rotational motion can be used to complete certain special process requirements, such as circular processing, spiral processing, etc.

3. Positioning and Angle Setting: CNC rotary tables can help machine tools achieve precise positioning and angle setting of workpieces. By accurately controlling the rotation angle and position, the workpiece can be processed at a specific angle, ensuring the accuracy and repeatability of the processing results.

4. Multi-station processing: CNC rotary tables usually have multiple working positions, which can clamp multiple workpieces at the same time and realize the function of simultaneous processing. This can improve production efficiency and reduce operation time.

5. Automatic control: The CNC rotary table can be linked with the CNC control system to achieve automatic processing and production. The machine operator can control the movement and processing of the table by simply inputting instructions.

The CNC rotary table of machine tools can provide higher flexibility and precision in the processing process by controlling the rotation, positioning and angle setting of the workpiece, providing important support for CNC machine tools to realize various process operations.
