    Abstract: A method of machining seats of a compressor piston having an approximately hemispherical recess. A surface of a piston extending perpendicular to an axis of the piston is machined by annularly moving a cutting element while the cutting element is rotated with respect to the piston to form an annularly cut portion. The surface is further machined by moving the same cutting element in a direction toward the surface while the cutting element and the piston are relatively rotated to form a hemispherical recess in the surface. The firstly formed annularly cut portion becomes an annular chamfered portion on the periphery of the hemispherical recess. In this way, it is possible to form the hemispherical recess, and the annular chamfered portion on the periphery thereof, with the common cutting tool.

    Abstract: A cutter plate, in particular a spherical face milling cutter, is provided for a cutting tool, and is made of a hard metal and has four wings with cutting edges. The cutting body, which is cruciform in a view from the front, has cutting edges, which extend from the area of the circumference of the cutting tool as far as its axis of rotation, or at least close to it. A simple clamping device, for example a clamping claw, is sufficient for fastening the cutting body on the tool body. The cutting body provides a distribution of the forces acting on one or several wings to all wings, in particular during interrupted cutting, wherein not all the cutting edges of the cutting body are in simultaneous contact with the workpiece, so that a good force transfer to the tool body is possible. The cutting body can be assembled from two individual cutter plates, which are plugged together.

    Abstract: The present invention relates to a rotary cutting tool assembly comprising a combination of a single ball nose cutting insert of a generally elongated configuration. The ball nose cutting insert is fixed into a holding body provided with a slot adapted to securely and non-movably hold the insert. The single ball nose cutting insert has at least one fill ball nose cutting end having a cutting edge of a continuous spiral fluted configuration. The fill ball nose cutting end comprises a cutting face consisting of two radius cutting edges meeting at a center or tip of the full ball nose cutting end forming a web. The cutting face forms a true helical path made of a continuous curve following a spiral shape, and helix angles of the radius cutting edges are between 3 to 45 degrees with respect to a longitudinal axis of the ball nose cutting insert in both right and left directions. The ball nose cutting insert has a solid configuration and comprises two identical reversible fill ball nose cutting ends formed on opposite ends of the insert. The radius cutting edges of the cutting faces are arranged to form a spiral or helical configuration, and the cutting faces of the single ball nose cutting insert are formed a grinding wheel.

    Abstract: A ball nose cutter having a replaceable single cutter insert in which the cutting edges thereof include a pair of mutually spaced apart cutting tips, one cutting tip at a time being selected for use by being located at the centerline of rotation of the ball nose cutter. The cutter insert is of circular cross-section for rotatably seating within a circularly cross-sectioned groove in a cutter body. A bore in the cutter insert is aligned with an off-axis threaded bore in the cutter body so that a holder screw which passes therethrough threadably holds the cutter insert with respect to the cutter body. A planar face is provided adjacent each cutting edge, wherein each planar face has an orientation so that the selected cutting tip is exactly located on the centerline rotation of the ball nose cutter.
