Title:
CUTTING BLADE
Document Type and Number:
Japanese Patent JPH01127272
Kind Code:
A
Abstract:
PURPOSE:To enhance dimensional accuracy of cutting decreasing the generation of flaw and chipping in a cut surface by applying work to an abrasive grain for dressing and truing in the side surface of a cutting blade. CONSTITUTION:A cutting blade, before it is mounted to a cutting machine, applies side surface truing, performing abrasive grain work on a side surface of the cutting blade formed by holding an abrasive grain 1 with a binding agent 2 and finishing the thickness into desired further uniform dimension, and side surface dressing selectively cutting off the binding agent 2 from this cutting blade and protruding the abrasive grain 1 serving as a cutting edge from the binding agent 2. Thus by applying the truing and the dressing to the side surface of the cutting blade, it enhances dimensional accuracy of thickness and accuracy of cutting width. In addition, decreasing waviness in a side surface shape of the cutting blade, placing the abrasive grain 1 to come into uniform contact with a cut workpiece and suppressing uneven contact of the cutting blade and generation of its vibration, the cut workpiece decreases the generation of flaw and chipping in its cut surface.
