An automatic tool changer is a device that facilitates the quick and efficient exchange of tools on a machine, particularly in CNC (Computer Numerical Control) equipment. Its primary function is to reduce downtime by enabling machines to seamlessly switch between different tools without requiring manual intervention. This capability is crucial in automated manufacturing environments where various operations must be performed sequentially.

By utilizing an automatic tool changer, a single machine can execute a range of operations, such as drilling, milling, and tapping, all within the same setup. This not only increases productivity but also ensures consistent accuracy and quality in machining operations. The automatic tool changer often incorporates a sophisticated control system that coordinates the tool selection process based on the programmed machining tasks, making it an integral component in modern automated machining processes.
