PROBLEM TO BE SOLVED: To enable highly precise automated working of a micro hole of a work. SOLUTION: The work W is held by a work chuck 11 so that the micro hole H of the work W directs in a vertical direction. While the tip of a straight wire 10 inserted into the micro hole H is grappled by wire clamps 51 and 51, the wire 10 is rewound by rotating a wire real 31 with a motor 34 for winding the wire, and is held in a suitable tension added state. The work chuck 11 for holding the work W made rotatable by an air blow 17, a driving belt 14 is mounted to the work chuck 11 to make it liftable vertically by the motor, and the inner peripheral surface of the micro hole H in the work W is slidably contacted with the outer peripheral surface of the wire 10 to be ground while the work W is being rotated and lifted.
