2. The positioning is accurate and reliable to prevent misoperation due to slight vibration.
3. The movement direction of the stone engraving machine equipment operating parts and the movement direction of the operated parts must comply with the regulations, and there should be a simple symbol mark.
4. Install the necessary interlocking mechanism to prevent uncoordinated operation of the operating parts and accidents caused by uncoordinated operation by multiple people.
5. The structure and arrangement of the handles, handwheels and buttons should meet the requirements. The start button should be installed in the cabinet or a guard ring to prevent accidental touch.
