Patent ID: 7874895

Claim:
A rotating cutting tool sharpening device comprising: a main base; a tool spindle assembly for holding a cutting tool for processing comprising: a spindle base reciprocatable on the main base; a first spindle, rotation of which reciprocates the spindle base; a rotating platform rotatable about a vertical axis on the spindle base; a first carriage for reciprocating the cutting tool in a first direction; a second spindle, rotation of which reciprocates the first carriage; a second carriage for reciprocating the cutting tool in a second direction; a third spindle, rotation of which reciprocates the second carriage; and a tool spindle mounted in the second carriage for receiving and reciprocating the cutting tool along a longitudinal axis of the cutting tool; and a motor tower assembly comprising: a tower base reciprocatable on the main base; a rotating platform rotatable about a vertical axis on the tower base; a frame extending perpendicular to the main base; and a motor reciprocatable vertically on the frame, and rotatable about a horizontal axis on the frame, wherein the motor is for rotating one of a plurality of interchangeable modifying tools; whereby the motor is positionable at an angle to the horizontal and perpendicular to the tool spindle with an end face of one of the modifying tools perpendicular the cutting tool in a first position, and parallel to the tool spindle with the end face of the modifying tool facing the cutting tool in a second position.
