    摘要: An apparatus for machining a cylindrical workpiece has a hollow spindle with a driving center on its tip end. The hollow spindle is rotationally journaled within a spindle unit. A tail stock spindle, with a centering center on its tip end, is rotationally supported and axially movable within a centering unit. A shaft-like kelly is non-rotationally and axially movably supported within an inner bore of the spindle. A drive rotates the spindle. Cylinders axially drive the kelly and the tail stock spindle, respectively. The spindle, the tail stock spindle and the cylinders are arranged on the same axial line. The cylindrical workpiece is sandwiched between the driving center and the centering center. An outer circumferential surface of the workpiece is finish machined while rotating the workpiece under a condition where the kelly engages the workpiece within an inner bore of the workpiece.

    摘要: Embodiments of the present invention may include a power tool having a driving motor, a spindle with a front tool and a continuously variable transmission mechanism. The driving motor is configured to output any number of output rotations. The continuously variable transmission mechanism is configured to shift the number of rotations from the driving motor in any ratio and output the shifted rotation to the spindle. The driving motor changes the number of output rotations. The continuously variable transmission mechanism changes the ratio. Both the driving motor and the continuously variable transmission mechanism serve to alter the rotational speed of the spindle.
