Why do you need to disconnect the power before changing the cutting disc on a metallographic cutting machine?

When operating the metallographic cutting machine to replace the cutting blade, the spindle cannot be started when the door panel is opened to prevent accidental startup or sudden operation of the equipment during the replacement process, which could lead to operator injury. This is an important safety feature of Chung-Tse's metallographic cutting machine, and we always put the safety of our customers first. In addition, power-off operation also protects the equipment itself, avoiding equipment damage caused by misoperation.
