A radius-forming dressing roll (32) having a frustoconical working region (48) and an adjoining concave-toroidal working region (49) is mounted on the dressing spindle (30) coaxially to a dressing disc (31). In a first step, the flanks (42, 43) of the grinding-worm thread are profiled with the disc (31). After the dressing spindle (30) has been pivoted, the two tip radii (46, 47) and the cylindrical outer circumference (45) are profiled with the dressing roll (32). With little resetting effort and high flexibility, the method permits profiling with short dressing times.

A device for sharpening a tool blade has a pair of spaced guide rails and a bracket for mounting a sharpening stone on the guide rails. A carriage is slidably supported on the guide rails and has a pair of spaced slide plates adjustably supporting a blade angle plate thereon. A clamp mechanism secures the tool blade on the angle plate which is secured in an adjusted position for forming a primary angle on the blade cutting edge by reciprocal movement of the carriage along the guide rails. The angle plate and attached tool blade are readjusted on the carriage for subsequently forming a secondary angle on the cutting edge of the tool blade. Printed indicia adjacent a plurality of adjustment holes formed in the slide plates set the primary and secondary angles of the cutting edge. Mating surfaces on the carriage and guide rails set the amount of material to be removed from the blade during reciprocal movement along an abrasive sharpening material.

The artificial diamond compact lathe tool grinding device has the advantages that high processing efficiency to artificial diamond compact lathe tools is realized, product quality is remarkably improved, grinding consumption is greatly reduced, and the like.

A cutting insert including a surface involved in cutting, for which a cutting tool material of a hard sintered body is used. A radius of a nose R portion is 0.4 mm or greater and 2.4 mm or less, an apex angle α of the nose R portion is 50° or greater and 95° or less, a rake angle β at a position of a bisecting plane of the apex angle of the nose R portion is 1° or greater and 10° or less, a chamfer provided in a cutting edge portion is a negative land with unequal width, and at least on one side of the negative land with respect to a boundary which is an apex of a nose R portion cutting edge, a width of the negative land gradually decreases from the apex of the nose R portion cutting edge to a position at which the nose R portion cutting edge is connected to a linear cutting edge. Let W1 be the width of the negative land at the apex of the nose R portion cutting edge, and W2 be the width of the negative land at both ends of the nose R portion cutting edge, then the W1 is 0.04 mm or greater and 0.2 mm or less, and a ratio of the W1 to the W2 is 1.5 or greater.

An apparatus includes a blade grinding machine, a measuring system and a control for providing a bar blade suitable for cutting work pieces. The blade grinding machine includes a clamping mechanism for mounting the bar blade and a grinding wheel for grinding the mounted bar blade. The measuring system also includes a clamping mechanism for mounting bar blade and at least one probe for three-dimensional sampling of the bar blade mounted on the measuring system. The control enables a data exchange between the blade grinding machine and the measuring system in order to grind and sample the bar blade in an alternating fashion. The apparatus is a closed system in which data exchange is automated.

The invention belongs to the field of manufacturing of gear cutters, and relates to a method for finishing a gear shaper cutter by the diagonal contour evolution of a conical worm grinding wheel. The worm grinding wheel is trimmed to be conical along the rotating axis of the worm grinding wheel, the gear shaper cutter is machined by adopting a diagonal contour evolution process, and the grinding wheel is also required to move along the radial direction of the gear shaper cutter in a machining process, so that the worm grinding wheel can be ensured to be approximately equivalent to a standard rack at different moments, and a gear shaper cutter capable of meeting an accuracy requirement can be machined.

The invention discloses a rotary cutter sharpening seat for a cutter, comprising a base, rotating pieces, a rotary shaft and a locking piece, wherein the rotary shaft is divided into X, Y and Z rotary shafts; the Z rotating piece is provided with a lathe tool mounting hole, the center line of which is vertical to the Z rotary shaft of the Z rotating piece; the Y rotating piece is provided with a YZ middle-position hole, the center line of which is vertical to the Y rotary shaft of the Y rotating piece; the Z rotating piece is sleeved in the YZ middle-position hole, the center line of which is collinear with the axis of the Z rotary shaft; the X rotating piece is provided with an XY middle-position hole the center line of which is vertical to the X rotary shaft of the X rotating piece; the Y rotating piece is sleeved in the XY middle-position hole the center line of which is collinear with the axis of the Y rotary shaft; the center line of the YZ middle-position hole of the Y rotating piece is crossed on the X rotating piece; the base is also provided with an X rotating support; and the X rotating piece is sleeved on the X rotating support, the rotating shaft of which is collinear with the X rotary shaft of the X rotating piece. When the rotary cutter sharpening seat is used, after a tool grinding machine provided with the cutter sharpening seat is clamped and lathed, continuous multi-face grinding can be performed at any blade surface angles to finish integral lathing and blade sharpening once, the operation of clamping for multiple times is avoided, and angle space conversion is not needed; the big lathing offset when the angle is regulated is eliminated; the rigidity of the cutter sharpening seat is improved; machining errors due to the cutter relieving phenomenon are reduced; and the locking reliability is further improved to increase the convenience in use and realize the miniaturization of a matched tool grinding machine and higher blade grinding precision.

An object of the present invention is to provide a cutting method and apparatus and a rib electrode for electric discharge machining which can cut a rib portion of a workpiece efficiently and accurately. For this purpose, a cutting tool 11 having cutting edges 23a, 23b extending in parallel or extending along two straight lines diverging toward the forward end in the same plane is prepared. The cutting tool 11 is arranged with respect to a workpiece W such that the two cutting edges 23a, 23b engage with the two opposed side surfaces of the rib portion R of the workpiece W. The cutting tool 11 is moved relative to the workpiece W along a desired machining path, to thereby cut the two side surfaces of the rib portion R of the workpiece W at one time.
