Abstract
PURPOSE: To perform cutting with good accuracy and massproduction by providing a plurality of whetstones along the direction forming cutting.
CONSTITUTION: The substrate 6 is bonded on the stage 6 and the whetstones 25 and 26 are mounted. Cutting is formed by reciprocating the table. Machining is made by setting the thickness t of the whetstone 25 thicker than the whitstone 26 and the cutting depth d of the whetstone 25 deeper than that of the whetstone 26. By turning the whetstone 25 clockwise, the substrate is fed circumferentially, and the whetstone 26 is turned counterclockwise, then notch and crack can be prevented. With this method, the load of spindle is smaller in comparison with the case installing a number of whetstones on the same shaft, and adjustment and mounting are easier. When the thickness of whetstones is made smaller in the order of treatment, the working resistance and heat dissipation are smaller and the accuracy can be increased
