The rightmost tool magazine tool holder 10 is clamped with the processing tool at the lower end of the automatic tool-changing spindle 3. The cylinder on the automatic tool-changing spindle 3 works to loosen the processing tool. The automatic tool-changing spindle 3 moves up, and the processing tool will stay on the tool magazine tool holder 10. Then the output shaft of the tool magazine motor 11 rotates, and the tool magazine tool holder 10 of the processing tool to be used is rotated to the lower part of the automatic tool-changing spindle 3. Then the automatic tool-changing spindle 3 moves down, and the processing tool is inserted into the automatic tool-changing spindle 3. The cylinder works to tighten and fix the processing tool. Then the moving motor 13 drives the moving seat 6 to reset to complete automatic tool change.
