Title:
A support pad for drill heads, and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6282817
Kind Code:
B2
Abstract:
A deep hole drill head support pad (50) whose edge chamfers (36, 38, 40) are formed in a continuous grinding operation so that there are no discontinuities in the angled side surface leading up to the outer surface (34) of the support pad (50). A method of manufacturing the support pad (50) includes generating a virtual guide metric comprising a curved travel path for a grinding surface around a support pad blank, and a plurality of control surfaces intersecting with the curved path at separate locations along its length, each control surface defining an angle of orientation of the grinding surface. A CNC grinding machine can interpret the virtual guide metric to change the angle of orientation of a grinding surface relative to a support pad blank as it moves between adjacent control surfaces in a continuous manner.
