Tools Clips or Automatic Tool Changer (ATC)
Tool Changer: The tool changer consists of a number of tool spindle docking stations (up to a maximum of 8, depending on what was ordered
with the machine). The machine knows the location of the docking stations and will recover and deposit tool spindles as commanded by the
program that it is running. Each time that a cutter is inserted into a tool spindle, the distance to the tip of the tool is different.
