1. When the spindle stops running, the spindle must be stopped first, and then the tool can be changed. This is a prerequisite.
2. The spindle moves to the tool change point, and the tool rotates to the preset tool rest.
3. The tool holder of the tool magazine moves towards the tool, and the tool just gets stuck in the tool holder. When the spindle moves upward, the cutter is released. The terminal position of upward movement is called "waiting point", that is, the position where the spindle is completely separated from the tool rest and does not affect the rotation of the tool rest.
4. Turn the tool to the tool holder to be replaced, move the spindle down to the tool changing position, and hold the handle.
5. The cutter head moves forward, so that the cutter can be separated from the cutter holder and return to the original position.
