Method of determining spindle speed

1, The higher the material hardness, the lower the machining spindle speed; The stickier the material, the higher the spindle speed during processing.
2, Determine the spindle speed according to the diameter of the tool, the larger the diameter of the tool, the lower the spindle speed.

3, Commonly used engraving machine spindle speed 18000 and 24000 revolutions of two.
