What function does a rotary table serve in CNC milling?

A rotary table is a critical accessory in CNC milling that enables the workpiece to rotate, facilitating machining from various angles. This capability allows operators to perform complex operations such as drilling, milling, and engraving on different surfaces of the workpiece without needing to reposition it manually. The versatility of a rotary table is particularly beneficial for producing intricate parts that require multi-faceted machining, improving both efficiency and accuracy in part production.

The other options do not align with the primary function of a rotary table. It does not serve to cool the machine, provide power to the CNC system, or act as a tool storage area. Understanding the rotary table and its capabilities enhances one's ability to utilize CNC milling machines effectively for advanced machining tasks.
