ABSTRACT:
A cutting apparatus for forming a noncircular cross-section on a workpiece that includes a tool advancing and retreating device. The tool advancing and retreating device includes a central shaft on which is to be mounted a tool, a journal for supporting the central shaft, a movable plate fixed to the central shaft, and electromagnets positioned opposite to one another such that the movable plate is interposed between the electromagnets with a clearance between the plate and the electromagnets. A device is provided for detecting the rotational angle of the main shaft and a displacement sensor is included for detecting the longitudinal displacement of the central shaft. A speed sensor detects the speed of the longitudinal displacement of the central shaft and an arrangement is provided for controlling the electric current passing through the electromagnets based on the output signals from the rotational angle detecting device, from the displacement sensor and from the speed sensor. The journal that supports the central shaft includes a mount and a plurality of leaf springs which are secured to the central shaft and to a holder. The holder is also secured to the mount.
