    TIPS:

    Under normal processing conditions, the main parameter affecting tool life of woodworking engraving machine is spindle motor speed. Under the same conditions, the lower the spindle motor speed, the longer the tool life. In order to prolong the service life of the tool, it is desirable to set a lower spindle speed, but the speed of the spindle motor can not be reduced indefinitely. When the speed of the spindle motor is too low, the cutting force becomes larger at the same feed speed, which makes the tool unbearable. So there is a reasonable rotational speed range for spindle when processing certain materials.
