摘要： For use with an indexable metal cutting tool, an improved holder assembly is disclosed which functions to maintain the position of an indexable insert during operation of the tool. More particularly, a holder assembly is described which includes a support member, connected to the cutter body of the tool, which includes a platform and a threaded aperture disposed normal to the plane of the platform. The latter includes a plurality of keys extending from the plane of the platform. A planar indexable insert having an aperture disposed normal to the planar surfaces thereof is disposed in abutting relationship with the platform of the support member, such that the apertures therein are in register. In addition, the planar surface of the indexable insert which is in abutting relationship with the platform includes receiving grooves which are adapted to be interengaged with the keys of the support member. The indexable insert is maintained in abutting relationship with the platform by a screw which extends through the registered apertures and is threadably engaged in said support member. The interengagement between the keys and the grooves of the support member and insert function to restrict unwanted rotational movement of the insert about the axis of the screw during use of the cutter.

摘要： A boring cutter which is adapted to be rotated about its central axis includes at least one insert pocket having opposed parallel leading and trailing walls, as well as a bottom wall. An insert seat of generally L-shaped configuration is provided, with the leading surface of the insert seat being in abutting relationship with the leading wall of the pocket. The opposed trailing surface of the insert seat includes both a leading and rear locating support surface adapted to receive an indexable cutting insert. A wedge is receivable between the rear surface of the cutting insert and the trailing wall of the pocket. The radial position of both the insert seat and the wedge, relative to the central axis of the boring cutter is adjustable. By this arrangement, the radial position of the cutting insert may be varied to thereby adjust the effective outer diameter of the boring cutter. In addition, the amount of overhang, or the difference in the radial position between the cutting insert and the wedge, remains constant thereby maintaining the structural support for the cutting edge of the insert.

摘要： An indexable finishing insert is disclosed formed from a flat wafer of cutting material having front and rear planar rake surfaces and a plurality of edge faces disposed therebetween. The rake faces are generally of equilateral, polygonal configuration with the side edges thereof corresponding to the cutting edges of the insert. The cutting edges are arcuate and have a radius of curvature several times greater than the width of the planar surfaces. The intermediate portion of each edge face is substantially planar and defines a locating land for facilitating the mounting of the insert within the pocket of a milling cutter. At least a portion of the opposed ends of each edge face is curved and sloped away from the front rake surface in order to provide clearance along the edge faces when the insert is mounted on a cutting tool at an angle between the rake surfaces and the workpiece.

摘要： A floating wedge is described for facilitating the mounting of an indexable insert in a pocket of an indexable cutting tool. The floating wedge includes a main body member having opposed leading and trailing surfaces and a swivel plate member having opposed leading and trailing surfaces. The leading surface of the main body member and the trailing surface of the swivel plate member are disposed in abutting relationship and are provided with complementary configurations, thereby enabling the relative slidable movement between the members such that orientation of the leading surface of the swivel plate member relative to the trailing surface of the main body member may be adjusted. The adjustability between the members enables full and equal contact pressure to be established between the floating wedge, the indexable insert and the walls of the insert pocket, thereby eliminating localized stresses and preventing insert failure. In a preferred embodiment of the subject invention, the trailing surface of the main body member and the associated wall of the pocket of the cutting tool are provided with complementary configurations. The latter arrangement allows for the relative movement between the leading surface of the swivel plate member and the walls of the insert pocket, thereby increasing the range of motion of the floating wedge.

摘要： A cutter insert is provided which is adapted to be supported on a flat platform on a cutter body and abutting edgewise against walls upstanding from said platform. The insert comprises a flat block of cutting material in the geometric shape of a parallelogram having a hole extending therethrough between the upper surface and the mounting surface of the block to receive a screw for securing the block to the platform. The upper surface of the block terminates at opposite ends in radii.

摘要： The subject invention relates to an improved assembly for mounting a finishing insert in a milling cutter. More particularly, the subject invention facilitates the adjustment of the tilt of a finishing insert relative to a milling cutter to improve the finish of a workpiece. In accordance with the subject invention, a milling cutter is provided with a finishing insert pocket having a planar bottom wall disposed at an inclined angle relative to the planar surface of the cutter. A locating seat, having a finishing insert fixedly mounted therein, is adjustably mounted within the insert pocket. By adjusting the position of the locating seat relative to the insert pocket, the angle of the cutting edge of the finishing insert, relative to the milling cutter is varied. In a preferred embodiment of the subject invention, both the insert pocket and the locating seat include complimentary arcuate walls to provide additional support during the cutting operation.

摘要： A milling cutter includes an array of pockets each having radially extending side walls and a base wall from which radially projects an elongated locating rail. A safety wedge has one surface in engagement with one wall of the pocket and its opposed surface in engagement with one surface of a cutting insert. The latter includes a central hole through which extends a projection extending from the safety wedge. One edge of the cutting insert engages the locating rail, while the opposite surface of the cutting insert is engaged by a wedge surface of a wedge assembly which is connected to the body of the cutting tool, and is selectively operable for shifting of the wedge assembly into wedging engagement with the cutting insert. By this arrangement, the cutting insert is clamped intermediate the safety wedge and the wedge assembly, and the edge of the cutting insert bears against the locating rail. As the milling cutter is rotated, the hard wedge assembly is behind the cutting insert and thus provides protection to the cutter body in the event of a wreck that would destroy the carbide cutting edge of the cutting insert. In addition, the hard safety wedge disposed ahead of the cutting edge protects the body from chip-erosion.

摘要： A milling cutter which is adapted to be rotated about a central axis includes at least one insert pocket having opposed leading and trailing walls, as well as a rear wall. An indexable insert having front and rear planar surfaces is receivable in the insert pocket, along with at least one locking wedge, which is interposed between the insert and the pocket walls for securing the insert within the pocket. In accordance with the subject invention, an adjustable locating wedge is provided for regulating the axial location on the insert. The locating wedge, a portion of which is disposed in abutting relationship with the axially lowermost cutting edge of the insert, is received within a groove located in the rear wall of the insert pocket. The receiving groove is aligned with the insert and extends radially inwardly from the periphery of the cutter body. In addition, the receiving groove is disposed at an angle relative to the rear wall of the insert pocket such that as the position of the adjustable locking wedge is varied within the groove, its axial position relative to the cutter body is also varied. By this arrangement, the axial position of the insert, which rests on the locating wedge, can be adjusted. More specifically, as the position of the locating wedge is varied within the groove, its axial position is varied, thereby varying the axial position of the insert. In a preferred embodiment, an adjustable insert seat is provided to vary the radial position of the insert.
