摘要： A tool holder includes an insert pocket having a support surface with a pocket recess occupied by a lever pin, and a fastening member. A head portion of the lever pin has a lever head rear contact surface, located above the support surface, for pressing against a bore of a cutting insert in the insert pocket. The fastening member engages a threaded recess which extends from the pocket recess along a threaded recess axis. The fastening member includes a guiding prong, located within a blind hole in the front of the lever pin. A clamping contact surface of the fastening member is adjacent to a lever front contact surface of the lever pin. A first longitudinal distance, between the lever rear contact surface and the lever front contact surface, is smaller than a second longitudinal distance, between the lever front contact surface and a lever rear contact surface.

摘要： In a cutting tool having an indexable cutting insert (20) with four cutting portions (26a, 26b, 26c, 26d), the cutting insert is securable within a holder portion in four index positions by means of a fastener. The cutting insert has two opposing end surfaces (22) with a peripheral side surface (24) and a central axis (c) extending therebetween, the peripheral side surface having exactly four abutment zones (28a, 28b, 28c, 28d). The insert holder (42) has a holder portion (46) and a body portion (48), the holder portion having a sidewall surface with a first, second and third reaction zone. The cutting insert is divided into four imaginary quadrants about its central axis and the four abutment zones are located entirely in two of the four imaginary quadrants, and for each index position, three of the four abutment zones are in clamping contact with the three reaction zones.

摘要： The present invention relates to a tool for machining a workpiece, comprising a tool body (1), a cutting tool (3), and fastening means (7, 8) for fastening the cutting tool (3) in a receiving recess (2) of the tool body (1), wherein the cutting tool (3) has a blade (31) and a continuous cutting tool bore (32), and wherein the tool body (1) has a continuous tool body bore (4) leading into the receiving recess (2). In order to create a simple possibility for replacing the cutting tool from different sides, when the tool is inserted in a machine tool, it is provided according to the invention that the fastening means comprises a locking bushing (7) provided with an internal thread (71) and a tensioning screw (8) provided with an external thread (81) corresponding to the internal thread (71) of the locking bushing (7), which are inserted into the cutting tool bore (32) or the tool body bore (4) from opposite sides in order to fasten the cutting tool (3) on the tool body (1), that the locking bushing (7) is screwed directly to the tensioning screw (8), regardless of whether it is inserted in the cutting tool bore (32) or in the tool body bore (4), and that anti-turn means (5, 6) are provided for preventing the locking bushing (7) for turning about the longitudinal axis thereof when screwed to and unscrewed from the tensioning screw (8).

摘要： A cutting tool (21) for, e.g., dressing electrode tips includes a toolholder (23) having an opening (25) extending through the toolholder from a top (27) of the toolholder to a bottom (29) of the toolholder along a central axis (C) of the toolholder, and a plurality of insert mounting pockets disposed around the opening for mounting replaceable cutting inserts, the plurality of insert mounting pockets including a center pocket (31), a top pocket (33), and a bottom pocket (35). The tool also includes a center insert (41) removably disposed in the center pocket, a top insert (43) removably disposed in the top pocket, and a bottom insert (45) removably disposed in the bottom pocket. When a top electrode tip and a bottom electrode tip are disposed in a dressing position relative to a top and a bottom of the opening in the toolholder and the tool is rotated, the center insert and the top insert dress the top electrode tip, and the center insert and the bottom insert dress the bottom electrode tip.
