Abstract: A side milling cutter with cutting inserts, by which side milling cutter a crank pin can be cut with a single feed motion. The plate-shaped cutting inserts are arranged on the periphery of the side milling cutter alternating between the left and right side in a peripheral direction, and are oriented essentially radially with their cover surfaces in relation to the cutter axis, which cover surfaces contain the tool faces. The cutting inserts are also arranged so as to form a gap on the periphery of the cutter which is so narrow that the length of the arc of action between the point of entry and the point of exit of cutting is greater than the half of the gap of the arrangement of cutting inserts on the periphery of the cutter. The present invention also relates to the configuration of the cutting inserts as indexable inserts which can be used on the left and on the right.

Abstract: A swing grinding fixture and process for using the same is disclosed that enables a conventional surface grinder to remanufacture a machine tool cutting insert by grinding a predetermined shape into the insert. A quick clamping insert holder coupled to a slide secures the tool insert in the fixture. A precision spindle cartridge is mounted in a rigid fixture body and coupled to the slide to provide the swing motion required to generate the radius to be ground. The rigid fixture body includes a pair of micrometer adjustable stops which limit the arc through which the slide may be swung and control the flank shape ground into the insert. In an alternative embodiment, a sine plate is attached to the fixture body and is used to incline the fixture to a predetermined insert rake angle. In operation, the grinding fixture is securely mounted to the table of a surface grinder and a cutting tool insert is secured in the insert holder. The grinding table is manipulated to align the grinding wheel with the axis of rotation of the spindle and the position of the insert is adjusted to manipulate the amount of material to be ground from the insert. The slide is then swung clockwise to contact one micrometer adjustable stop and counterclockwise to contact a second micrometer stop, whereby a predetermined radius, substantially equal to the radius of rotation, is ground into the edge of the tool insert.

Abstract: An indexable insert for milling includes a metal base made of cemented carbide, and a cutting edge consisting of a sintered CBN compact and a flat drag type cutting edge which are brazed to the metal base or bonded thereto by integral sintering. A subcutting edge angle (.beta.), a negative land angle (.theta.) and a negative land width (L) are set at 30.degree. to 60.degree., 30.degree. to 45.degree. and 0.05 to 0.40 mm respectively, while the subcutting edge has a straight shape. Due to this structure, the indexable insert has excellent cutting performance particularly in face milling of parts which are made of gray cast iron, and the tool life can be extended.

Abstract: The milling cutter comprises a body (1) having two indentations (4,5) each presenting a housing (4',5') the body of which makes with the longitudinal axis of the body a helix angle which is not equal to zero. In each housing a cutting insert (6,7) is removably fixed which comprises a tip portion emerging on the frontal face (9) of the body and a main cutting edge extending beyond and along the external lateral rim of the indentation. The position and the shape of this insert are such that the radial cutting angle is not equal to zero and is constant, and that the clearance angle is constant with a wedge angle of the insert which is also constant.

Abstract: An indexable cutting insert (10) for a tool (18) adapted to cut internal right-angled corners in a work piece (19). The insert (10) has a square configuration and comprises a top major surface (11), a bottom major surface (12) and connecting side surfaces (13). The lines of junction between the top major surface and the side surfaces define the main cutting edges (14) and the minor cutting edges (15). The main cutting edges (14) transite into the second cutting edges (15) in the corners of the insert. Each second cutting edge (15D) projects from the square basical shape so that it will lift the inactive main cutting edge (14A) from the machined surface under the insert.
