Support pad for a drill head and method for designing and manufacturing a support pad

摘要

A deep hole drill head support pad whose edge chamfers are formed in a continuous grinding operation so that there are no discontinuities in the angled side surface leading up to the outer surface thereof. A method of manufacturing the support pad includes generating a virtual guide metric including 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.
