Claim:
1. A device for grinding a tool, comprising: a main base having first and second tracks oriented at a right angle to one another in first and second directions; a tool spindle assembly for holding the tool for grinding, the tool spindle assembly including a spindle base reciprocatable on the main base along the first track in the first direction; and a tool spindle mounted on the spindle base for receiving and reciprocating the tool along a longitudinal axis of the tool and parallel to the first direction; a grinding wheel for grinding the tool; and a motor tower assembly for supporting the grinding wheel at different orientations relative to the tool, the motor tower assembly including a tower base reciprocatable on the main base along the second track in the second direction perpendicular to the first direction, the tower base being rotatable on the main base about a vertical tower axis; a motor for rotating the grinding wheel about a motor axis, a motor tower platform rotatable on the tower base about a vertical tower axis; a frame mounted on the platform for supporting the motor with the motor axis intersecting the tower axis, the motor being tiltably mounted in the frame for tilting of the motor axis from horizontal to an angle to horizontal about a tilt axis intersecting with and perpendicular to the motor axis; whereby the motor is movable from a first position wherein an end face of the grinding wheel is parallel to the tool axis and vertical or at different angles from vertical, to a second position wherein the end face is perpendicular to the tool axis and vertical or at different angles from vertical so that the end face of the grinding wheel faces an axial end face of the tool in the second position, or is positioned beside the cutting tool behind the axial end face, the tower base in the second position partially overlapping the first track.
