What is a tool carousel designed for in CNC milling?

A tool carousel in CNC milling is primarily designed for holding tools in various positions to facilitate efficient tool changes during machining processes. It is an essential component of CNC machines, allowing them to automatically switch between different tools as needed for various operations such as milling, drilling, and tapping. This functionality is critical for reducing downtime and increasing production efficiency, as it enables the machine to perform complex tasks without manual intervention or interruption.

The design of the carousel allows multiple tools to be stored in a compact arrangement, making it easy for the CNC program to call upon the required tool at the appropriate time during a machining cycle. This automation is crucial for maintaining high levels of productivity in manufacturing environments.

In contrast, tools do not provide power themselves but rather rely on the machine's spindle motor for that aspect, while coolant storage and monitoring performance are also handled by separate systems or components within the CNC machine, not the tool carousel itself.
