Automatic Tool Changer (ATC)

The automatic tool changer, short ATC, on a machining center is a mechanical device for automatic exchange of tools or process-related tools such as probes, grippers or plug gages. With the help of the tool changer tools from the machine’s tool magazine are changed in the machining spindle and vice versa. The exchange process is either handled with single- or double hook systems or directly from the magazine to the spindle (Pick-Up-changer).
