METHOD FOR MASKING AND COATING CUTTING TOOL AND CUTTING TOOL HAVING WEAR-RESISTANT COATING IN SELECTED LOCATIONS

摘要

A method in which a cutting tip is ground to form an intermediate cutting tool; a first predetermined portion of the intermediate cutting tool is masked; a wear-resistant material is deposited onto the exposed portion of the intermediate cutting tool to form a sharpened cutting tool; and a workpiece is cut with the sharpened cutting tool.

主权项

1. A method for forming a sharpened cutting tool from an intermediate cutting tool, the intermediate cutting tool having a ground cutting tip that comprises a face and a sharpened cutting edge at a distal end of the face, the ground cutting tip being relieved on a side and an end that cooperate with the face to define the sharpened cutting edge, the method comprising:
masking the intermediate cutting tool such that a first predetermined portion of the intermediate cutting tool is unmasked, and a second predetermined portion of the intermediate cutting tool is masked, the first predetermined portion including the sharpened cutting edge and at least portions of the end and the side that cooperate to define the cutting edge; and depositing a wear-resistant material onto the first predetermined portion of the intermediate cutting tool to form the sharpened cutting tool.
