摘要： A controller for a machine tool, capable of performing ultraprecision machining with high accuracy by performing correction allowing for a displacement of a spindle produced depending on a rotational speed. When the spindle is rotated at high speed, the cutting position of a tool attached to the spindle varies due to the influence of spindle fitting accuracy and of weight balance. By measuring the displacements in the X, Y and Z directions of the end of the tool (2) attached to the spindle (1) by means of non-contact displacement gauges (6x,6y,6z), correction amounts are obtained in the manner associated with the rotational speed of the spindle, and stored in a storage device. In the process of machining, correction amounts are read depending on the speed of the spindle, and machining is performed according to program command values corrected using the correction amounts thus read. Even if the cutting position of the tool varies during high-speed rotation, machining is performed according to program command values corrected. Thus, ultraprecision machining can be carried out with high accuracy.

摘要： A plurality of balancing structures are disposed in weight accommodation holes which extend in a radial direction and spaced at equal angles in a rotating plate constituting part of a rotating body on which a rotation object is mounted. A balancing weight having a male thread is disposed in each weight accommodation hole and is screwed into a female thread formed in the accommodation hole. A spring adjoining the weight is compressed by a stopper fixed in the weight accommodation hole at the outer end of the rotating plate. The weight can be turned with a tool inserted through holes provided in the spring and stopper to adjust the radial position of the weight and thereby balance the rotating body.

摘要： The length of the bearing surface in the movable portion (2) which moves linearly is larger than the length of the bearing surface in the fixed portion (1) by the stroke of the movement. With this configuration, the bearing surface on the side of the fixed portion always opposes the bearing surface on the side of the movable portion. An air supply source is connected to the fixed portion (1), and a plurality of air discharge openings (4) through which air is injected are disposed in the bearing surface of the fixed portion to constitute an air bearing. Only the side of the movable portion where the fixed portion is inserted is open. A coil (5) is disposed on the fixed portion and a magnet (6) is disposed on the movable portion so that a linear motor is constituted, thus providing a linear driving device. Cables (9) and the like for supplying compressed air or power are connected to the fixed portion (1), not to the movable portion (2), thus no external pressure is applied from the cable and the like, and highly accurate operation is achieved.
