摘要： A multiple spindle bar machine (10) includes in its preferred embodiment three main spindles (66) that are opposed by three counterspindles (106) of substantially identical construction. The main spindles (66) can be indexed about the Z axis. The counterspindles (106) cannot be indexed, but they can translate along the Z-axis. Each main spindle (66) is hollow and contains a workpiece-grasping collet chuck (68). At least one of the counterspindles (106) contains a workpiece-grasping collet chuck (108). The main spindles (66) are rotated in unison, but the counterspindles (106) are rotated independently by computer-controlled motors. In the preferred embodiment, three tool-carrying turrets (20A, 20B, 20C) are radially spaced around the machine at three work stations. Preferably, the turrets (20A, 20B) located at the first and second workstations can be moved along both the X and Z axes, while the turret (20C) located at the third workstation can be moved along the X axis. A slide-mounted cutoff (22) that moves along the X axis is located at the third workstation.

摘要： An automatic lathe bar magazine comprises a feed channel (11) for a bar to the lathe chuck and a powered bar pusher (15) grasping with a head collet (17) the tail of a bar in the channel to cause it to run therein. The bar pusher (15) is made telescopic to have an outermost part (18) running with reduced side play in the channel (11) acting as a guide therefor and an internal part (16) with smaller diameter bearing at its head said collet (17) and growing longer on command from the outermost part to protrude from the magazine and enter the lathe. In this manner the bar being machined does not touch the channel and this greatly reduces vibrations and noise produced by the high speed rotation of the bar.
