To continuously measure a height position of a cutting edge surface of a cutter in a longitudinal direction, and to shorten a measurement time.
A cutter grinder is provided with: a bed 5 supported with a chuck 3 for fixing the cutter 1 formed with the cutting edge surface 1a along the longitudinal direction over the whole length; a grinding wheel device 9 provided movable in a longitudinal direction of the bed 5 and having a cup-like grinding wheel 7 liftably provided so as to be opposed to the cutting edge surface 1a of the cutter 1 and formed to a circular cross section; and a cutting edge surface position measurement device 11 for measuring the height position of the cutting edge surface 1a of the cutter 1. The cutting edge surface position measurement device 11 is provided with a ball nut supported on a support member provided movably with the grinding wheel device 9 movably in a vertical direction; a ball screw thread-engaged with the ball nut and rotatably supported on the support member; a motor 76 connected with a drive shaft on the ball screw and supported on the support member; and a measurement element supported on the ball nut and provided in a vertical direction so as to be opposed to the cutting edge surface of the cutter. The measurement element has at least a roller 83 provided rollably in a movement direction of the grinding wheel device.
