    摘要: A wood-turning lathe includes a spindle and a drive shaft journalled to a headstock housing. A motor is mounted in the headstock housing, and includes a rotor. A torque converter includes a first wheel that co-axially surrounds the spindle and that is securely coupled to the rotor, a second wheel mounted securely on the drive shaft, and a belt trained on the first and second wheels, thereby increasing torque of the drive shaft. A speed change device includes a first pulley unit mounted on the drive shaft and defining a first belt-engaging surface, a second pulley unit mounted on the spindle and defining a second belt-engaging surface, and a non-elastic belt interconnecting the first and second pulley units and frictionally contacting the first and second belt-engaging surfaces.

    摘要: A cutting machine has a plurality of switches, each switch corresponding to a predetermined cutting speed for each of one of the various groups of materials to be cut, the materials having different machinablility qualities. One of a plurality of constant voltage output means are connected with one of each of the plurality of switches for changing the speed of the cutting tool responsive to the constant voltage output means.

    摘要: The cutting force applied between the cutting tool and the workpiece of a machine tool is periodically pulsated to expedite removal of material from the workpiece. The periodic cutting force pulsation is produced by periodically varying the spindle speed or the feed rate or both. In one embodiment, the periodic speed variation is produced by universal joints in the spindle drive and worktable drive. In a second embodiment, the periodic speed variation is produced by elliptical gears in the spindle drive and worktable drive.

    摘要: A drill press including a tool spindle mounted in a quill assembly having a toothed rack thereon which cooperates with a drive pinion to move the quill and spindle up and down. Retainer means on the upper end of the quill includes a relief notch terminating in a retainer lug which prevents the quill from inadvertently being driven downwardly past the drive pinion.
