    摘要: In a wire saw, it is an object to reduce the variance in width of cut slices of a work as well as the degree of coarseness of the cut slices. A plurality of machining rollers 13 and 14 are arranged in parallel at prescribed intervals, and a large number of circular grooves 13a and 14a are formed on the outer periphery of each of the rollers. In an axial direction of the machining rollers 13 and 14, a plurality of supply reels 23, take-up reels 24 and wires 15A, 15B are arranged. The wires 15A, 15B supplied from the supply reels 23 are wound on the circular grooves 13a ad 14a of the plurality of machining rollers 13 and 14 so that they are travelled between the plurality of rollers 13 and 14, and taken up by the take-up reels 24. The work 20 is cut/sliced by a lapping operation of abrasive grains contained in the slurry which are supplied on the respective sets of wires 15A and 15B which travel between the plurality of machining rollers 13 and 14 in a longitudinal direction over respective halves of the rollers.

    摘要: A wire saw which can improve a working accuracy is provided. When a wire goes to a rightward direction by a rotation of a moving motor, the wire is inclined in such a manner as to be moved toward a right and outer periphery from an inner portion of a work, and a cutting start point of the work becomes a point within the work. Further, when a wire goes to a leftward direction by a rotation of the moving motor, the wire is inclined in such a manner as to be moved toward a left and outer periphery from an inner portion of a work, and a cutting start point of the work becomes a point within the work. Then, the work is cut from the cutting start point by a sufficient slurry containing float abrasive grains supplied to a portion on the wire.

    摘要: A servomotor control system for multi-axes in which a single servo-amplifier can operate m rotational speed control loops and m current control loops as well for m servomotors simultaneously, where m is a predetermined integer greater than unity, while a single positioning controller with a signal teaching box can handle n servo-amplifiers in parallel, where n is a predetermined integer greater than unity, thereby mn servomotors in total can be controlled by a single system. In the system of the invention, the multiple servomotors can be divided into groups each including up to six servomotors to be controlled as a group and independently from servomotors belonging to other groups. The system of the invention can easily be expanded by a minimum addition of servo-amplifiers and/or positioning controllers to include servomotors more than mn, in which addition of one or more teaching boxes is possible whenever they become necessary.
