    Abstract: A continuous working system of a press machine includes a ram, an operation shaft which vertically moves the ram, and a servo motor which operates as a power source of the ram and which generates ram pressure using a torque based on at least one speed-torque characteristic of a motor. The operation shaft is directly driven using the servo motor. The operation shaft is continuously reciprocated and turned through an angle range corresponding to a distance between a predetermined lower end position required for press working by the ram and an upper end position such that the ram vertically moves between these positions by the servo motor, thereby subjecting a work to a continuous press working. The upper end position is set to a position slightly below a medium height of the entire vertically possible stroke of the ram. The lower end position is set to a position slightly above a bottom dead center of the entire vertically possible stroke of the ram.

    Abstract: A band saw machine includes a driving wheel and a driven wheel around which an endless band saw blade is wound. At least one of the driving wheel and the driven wheel is directly connected to an output shaft of a control motor. The output shaft of the control motor is arranged in a cylindrical bearing unit installed on a motor base supporting the control motor. The driving wheel is rotatably supported by the bearing unit.

    Abstract: To eliminate defects such as burr, rollover, sags, scar, etc. from cut-off surfaces of a workpiece in a turret punch press, for instance, a novel height-different punch formed with a lower front edge, an upper rear edge, and an intermediate edge extending between the two edges is used for the punch press. While feeding the workpiece on a horizontal plane in a predetermined direction, the punch is struck by a striker at a first stroke so that the lower front edge thereof cuts off the workpiece partially in cooperation with a die; at the succeeding strokes so that the intermediate edge thereof cuts off the workpiece mincingly and curls refuse within a recess of the die; and at the last stroke so that the upper rear edge thereof cuts curled refuse away from the workpiece to complete a multistroke punching operation.

The operation shaft is directly driven using the servo motor. The at least one speed-torque characteristic of the servo motor is set in a manner such that a motor torque of the servo motor at which a capacity of electric energy supplied by a servo amplifier is determined becomes the motor torque at which an optimal punching pattern of the ram is generated from a light load to a heavy load according to a type of workpiece to be worked by the press machine.
