  • Patent number: 11504857
    Abstract: In order to respond flexibly to various processing modes, such as forming curved surface shapes, when cutting a workpiece using a wire saw, this wire saw device (1) is provided with: a single robot arm (2) that is capable of moving freely by means of multi-axis control; a wire saw unit (3) that is detachably connected to the robot arm (2) via a tool changer (7); a wire (8) that spans a plurality of pulleys supported within the wire saw unit (3); and a workpiece cutting zone (20) that is established between the pulleys. The workpiece is cut to a prescribed shape by moving the robot arm (2) in a preset direction while running the wire (8) of the wire saw unit (3) and pressing the wire (8) against the supported workpiece.
    Type: Grant

  • Patent number: 7387118
    Abstract: The invention provides a wire saw in which wire tension fluctuations occurring in swinging of a row of wires can be accommodated to thereby increase a velocity of the wire and to carry out cutting with efficiency and precision by utilizing swinging of the row of wires even with thin wire. In the wire saw having the row of wires formed by winding the wire about a plurality of work rollers provided to a swinging disk many times, for pushing a workpiece against the row of wires caused to reciprocate or travel in one direction at high velocity to cut the workpiece into a plurality of pieces, and for swinging the row of wires in cutting of the workpiece, a feed side pulley for guiding feed side wire going into the work rollers to the work rollers and a retrieving side pulley for guiding retrieving side wire going out of the work rollers to an outside are disposed coaxially on an axial center of rotation of the swinging disk so that the tension fluctuations do not occur in the wire even if the row of wires swings.
