摘要： This disclosure relates to a machine tool comprising a tool holder which rotates relative to a workpiece to be machined and has a tool axis, and a plurality of cutting inserts that are removably attached to the tool holder, the active cutting edges of said cutting inserts having a common cutting circle which is coaxial to the tool axis. According to this disclosure, the tool holder has a cylinder-type insert seat shell for radially positioning the cutting inserts, which rotates about the tool axis. The cutting inserts have at least one contact surface that can be brought into contact with the insert seat shell.

摘要： A device for mechanically removing material from a workpiece or bulk feedstock, thereby creating chips of removed material while producing a new surface on the workpiece or bulk feedstock. The device comprises a body and at least one round cutting insert that is tangentially mounted on the body. Location and orientation of the insert is characterized by a reference plane offset and an insert axis angle. The insert has an outwardly-facing rake surface on which chips are formed. A planar flank surface is oriented relative to a cutting motion so as to provide clearance between the cutting insert and the surface created by removal of a layer that is converted into chips. A circular cutting edge lies at the intersection of the flank and rake surfaces.

摘要： A boring head has a connecting rod, an extending bracket and a cutter mount. The extending bracket is detachably connected with the connecting rod. The cutter mount is securely connected with a front end of the extending bracket. Because the extending bracket is detachably connected with the connecting rod, the extending bracket is replaceable, and the length of the extending bracket can be changed to make a bore with a desired diameter.

摘要： A boring tool for use in a tool holder, such as a boring head, that is driven about a drive axis and includes a pair of parallel bores for mounting boring tools generally includes a body including a cutting edge and a pair of mounting shanks for mounting in the bores of the tool holder. Preferably, the mounting shanks can be mounted in either bore and the cutting edge is disposed on the body so as to be different distances from the driven axis depending upon in which bores the mounting shanks are mounted.

摘要： A clamp for indexable inserts used especially for turning. The clamp consists essentially of a clamp shaft and a clamp head combined with it in one piece. The clamp shaft can be secured to an axis-parallel clamping surface of a tool holder by a supporting surface obliquely transfixed by a clamping screw. The clamp head has an open-edged recess to take the indexable insert, one effective cutting corner of which projects on one side beyond the outer surface away from the support surface. In order to be able to adjust the distance between the clamping surface and the cutting corner, the clamp head has, in the free region between the recess, the supporting surface and the clamp shaft, a slot-like aperture having a curved cross-sectional shape open towards the clamp shaft. The clamp head can be elastically bent with respect to the clamp shaft under the effect of an adjuster.

摘要： A substantially conical tool body 1 has a groove 11 extending in the direction of generating line. The groove 11 slidably receives a slider 16 carrying a cutting insert 5A. A spacer 12 having serration grooves 12a is interposed between one wall surface 11a of the groove and the slider 16. Serration grooves 16a are formed in one side surface of the slider 16. A wedge member 13 is detachably interposed between the wall surface 11b of the groove 11 and the slider 16 so as to press the slider 16 to bring the serration grooves 12a16a into engagement with each other. Any wear and deformation due to cutting load appear on the spacer 12 and the wedge member 13, so that original mounting and positional precision of the slider 16 can easily be recovered by renewing these members, thus maintaining a required level of machining precision.

摘要： A quick-change tool holder includes locating means for repeatably locating a cutting unit at a predetermined angular position with respect to a support member. The support member includes an axial bore for receiving a tubular shank on the cutting unit. The tubular shank of the cutting unit includes a keyway having a first locating surface along one side thereof. The clamping mechanism includes a key having a second locating surface along one side thereof. Upon actuation, the clamping mechanism imposes a torque force on the cutting unit to rotate the first locating surface on the cutting unit into abutting relationship with the second locating surface on the key to repeatably locate the cutting unit at a predetermined angular location. The torque force imposed on the cutting unit by the clamping mechanism therefore overcomes any inaccuracies in center-height adjustment attributable to the tolerance between the key and its corresponding keyway.

摘要： In a device for connecting two tool parts (1, 4) one tool part (1) is provided with a cylindrical fitting plug (2) which can be inserted in a fitting bore (5) provided in the other tool part (4). The fitting plug (2) has a transverse bore (6) with a radially displaceable tensioning pin (7) therein, which carries extensions (8) at its two ends, which engage in conical recesses (11) of two diametrically opposite tensioning elements (9, 10) arranged in the other tool part (4). The extensions (8) of the tensioning pin (7) have a hemispherical peripheral surface (8a) whose radius of curvature (R) as well as the apex angle (.alpha.) of the conical recesses (11) are so dimensioned that the hemispherical peripheral surface (8a) and the conical recess (11) touch at a force contact point (P) which lies radially spaced (r1, r2) from the free ends (8b, 9a, 10a) of the extensions (8) and the tensioning elements (9, 10), and that the lines of action (W) of the forces (K) acting at the two force contact points (P) extend at an angle (.beta.) at approximately 30.degree.-60.degree., preferably approximately 45.degree., to the axis (A2) of the transverse bore (6).
