Abstract: A rotatable tool for chip removing machining includes two parts, viz. a holder part, rotatable around a geometrical center axis, and a replaceable cutting part, which is rigidly connectable to a front end of the holder part via a male/female coupling. The coupling includes a tapering seat in the holder part and a tapering male member, protruding rearwardly from the cutting part. In the seat, there is a slot, which separates two elastically deflectable projections, that may be inwardly deflected towards each other during clamping of the male member in the seat. The male member is elongated in a radial direction, and the seat is in the form of a radial groove into and out of which the sheath body is transversely movable. The male member includes a dove-tail shaped portion received in a dove-tail shaper portion of the groove. A centering button on the male member enters a depression in the holder part to axially center the cutting part.

Abstract: An amorphous carbon coated tool includes a base material of WC base cemented carbide, and an amorphous carbon film formed on this base material. The cobalt content in the base material is at least 12% by mass. The maximum thickness of the amorphous carbon film is at least 0.05 nullm and not more than 0.5 nullm at the cutting edge. The amorphous carbon film is deposited with graphite as the source material by physical vapor deposition in an atmosphere substantially absent of hydrogen. The amorphous carbon film coated tool superior in wear resistance and adhesion resistance is preferably applicable to rotating tools such as drills, end mills and reamers, indexable inserts used for milling cutters and turning tools, and cutting-off tools such as cutters, knives, or slitters.

Abstract: The invention relates to a tool holder for use in machine tools, comprising a main body, which can rotate about an axis of rotation, and cutter holders which each hold a cutting plate and can be radially adjusted by means of an axially displaceable control rod and coupling means. In order to further develop said tool holder so that it is possible, within a very short time, to produce a turned groove which satisfies stringent demands regarding surface quality and geometric roundness, it is proposed, according to the invention, that the tool holder has at least two cutter holders which can be radially adjusted between a retracted position and an extended position and whose cutters can be simultaneously brought into engagement with the workpiece in order to produce a turned groove.

Abstract: In order to improve durability, machining stability, machining accuracy, etc. of a throwaway cutting tool in which a cutting head having a cutting edge is detachably mounted to the tip of a tool body using a clamping tool so that its function can be regenerated by replacing the cutting head, protrusions 8, 16 having their height gradually increasing and recesses 9, 15 having their depth gradually increasing from the center toward outer periphery of the tool are formed alternately with each other in a radial arrangement on the front surface of the tool body 2 and a support surface of the cutting head 3, which is formed by sintering, respectively. The protrusions and recesses, which are provided so that their positions correspond to each other, are conically engaged, thereby centering the cutting head and preventing its movement.

Abstract: The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360null. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.
