Abstract
The present invention relates to an improved tool grinding mechanism for grinding single point diamond cutting tools to precise roundness and radius specifications. The present invention utilizes a tool holder which is longitudinally displaced with respect to the remainder of the grinding system due to contact of the tool with the grinding surface with this displacement being monitored so that any variation in the grinding of the cutting surface such as caused by crystal orientation or tool thickness may be compensated for during the grinding operation to assure the attainment of the desired cutting tool face specifications.
Claims5
A tool grinding machine comprising a rotatable grinding wheel, tool holding means for holding a tool to be ground to desired tolerances, bearing means for supporting the tool holding means in a relatively movable manner therewith along a path in a single plane, pivotal means coupled to said bearing means for rotating the tool holding means over a preselected arc on an axis perpendicular to said plane and parallel to the face of the grinding wheel, moving means disposed intermediate said pivotal means and said bearing means for effecting relative displacement of said bearing means and the tool holding means supported thereby along said plane, sensing means coupled to said tool holding means for sensing said relative movement of said tool holding means within said bearing means when the tool is placed in contact with said grinding wheel by said moving means and when the tool holding means is displaced about said arc while in said contact with the grinding wheel, and spring means engaging said tool holding means for continually urging the latter along said path towards said grinding wheel.
