    摘要: In a single-wire type wire saw, a work is fed relatively to a wire stretched between a pair of grooved guide rollers disposed in the same direction and the work is cut by traveling the wire. When a cutting-feeding direction changes during a cutting of the work, an operation shaft is moved along an arc around the center axis of the wire in a cutting area and simultaneously support arms are rotated around the operation shaft to thereby oppose the wire support direction of the pair of grooved guide rollers to the cutting-feeding direction.

    摘要: A center hole machining method includes first to fifth steps. The first step includes obtaining outer peripheral shape data of a plurality of portions of the shaft blank in an axial direction. The second step includes obtaining a center axis by comparing measured data of the portions of the shaft blank with design data. The third step includes calculating a minimum distance from the center axis to the outer periphery in each of the portions of the shaft blank. The fourth step includes shifting the center axis in a direction of making the minimum distance greater than the machining dimension and repeatedly executing the third step when the minimum distance is less than or equal to the machining dimension. The fifth step includes boring the center hole in an end surface of the shaft blank at a position arranged on a line extended from the center axis.

    摘要: A horizontal machine tool (1) includes a base frame (10) where workpiece support faces (11c) for supporting a workpiece are formed at front portions; an X-axis saddle (20) attached to a back-face portion (12b) of the base frame (10) through an X-axis movement mechanism (50) universally slidably in a left-right direction; a Y-axis saddle (30) attached to the X-axis saddle (20) through a Y-axis movement mechanism (60) universally slidably in an up-down direction; and a spindle device (40) attached to the Y-axis saddle (30) through a Z-axis movement mechanism (70) universally slidably in a front-rear direction. According to this configuration, it is possible to make a whole of the horizontal machine tool a small size and lightweight and to enhance machining accuracy of the workpiece.
