Abstract: Disclosed are a cutting plate for a processing tool, particularly a milling tool, and a holding device for such a cutting plate. Said cutting plate comprises at least one blade (1) which is configured in a radially protruding manner on a central body (5) of the cutting plate. The central body (5) is provided with a coupling part for mounting the cutting plate on a frontal seat of a shaft-type holding device (15) which defines a longitudinal axis. Said coupling part forms at least one driving surface transmitting an operating torque from the holding device (15) to the cutting plate. The inventive cutting plate also comprises a shaped part which forms a fixing device on the seat (17) of the holding device (15) in cooperation with an associated embodiment (35).

Abstract: The invention relates to a cutting machining tool, especially of a boring bar type, comprising a holding device (10), one end of which is provided with a fixing shaft while the other end thereof is provided with a seat (12) for a removable cutting member (16). Said cutting member encompasses a support part (18) which engages at least partly into the seat (12) in the fixed state and a machining part (20). The support part (18) can be fixed in a clamping manner in the seat (12) by means of a fastening part (22). The seat (12) is provided with a rest area (28).

Abstract: The invention relates to a machining tool, especially a milling tool, comprising a shaft-like holder defining a longitudinal axis (13), a seat (9) being provided in the front face of the holder for a cutting plate that can be inserted into said holder. The cutting plate has a coupling part serving for mounting in the seat (9) of the holder. The coupling part has three ribs which project axially from the end surface of the cutting plate that is opposite the holder and which extend radially. Said ribs are provided for engagement in complementary grooves (31) configured in the seat (9) of the holder, the side walls (37 and 35) thereof forming driving surfaces and support surfaces, which interact for transmitting a machining torque, or as axial position safety-catch, with corresponding surfaces of the flanks of the ribs of the cutting plate.

Abstract: Tool holder for cutting bodies (5), which may be mounted on a base holder (15) by means of a fixing device (41), and a stop, cooperating with the above, running in a planar embodiment in the direction of the tool holder. A positive positional fixing against any movement along the three axes of the spatial coordinate system may be obtained, whereby the planar embodied stop is divided into planar sections (19, 21), by means of a machined recess (23), between which the recess (23) forms a seat for housing a projecting matching body (25) on the base holder (15) and the walls of the recess (23) form support surfaces (31, 33) for the matching body (25) which each define differing planes, embodied in a planar manner perpendicular to the stop, such as to feed the displacement and torsional forces resulting from the cutting force into the matching body (25) of the base holder (15).

Abstract: The invention relates to a cutting device comprising a holder (10), which is provided with a jaw-like opening (24) on a clamping head (20) that serves to accommodate a metal-cutting tool (22). The jaw-like opening (24) is located on a longitudinal side (16) of the clamping head (20) and its face (28) extending transversal to said longitudinal side (16) faces a workpiece (30) that rotates during metal-cutting machining. The face (28) is provided, at least in the area in which it leads into the opening (24), with a camber (32) whose curvature corresponds to the curvature of the workpiece (30) having the largest diameter.

Abstract: The invention relates to a cutting tool, in particular for the turning out of drillings, comprising a clamping piece (10) for fixing the tool in a clamp holder. Said clamping piece (10) comprises two clamping surfaces (30), which converge on each other in the direction of the one side (32) of the clamping piece (10) and in the direction of the other side (34) of the clamping piece (10) run into a roof-type surface (36) and, on the side of the clamping piece (10) facing away from the clamp holder, connect to a rod-like neck piece (12), which tapers in cross-section relative to the clamping piece (10) the free end of which is connected to a cutting piece (14) as one piece, provided with a cutting edge (16) on the external end thereof to which a face (18) of the cutting piece (14) connects in the direction of the neck piece (12).

Abstract: The invention relates to a rotary tool comprising a shank (1) which can be coupled to a rotary drive and comprises a head piece (3) on the free end thereof which can be detachably connected in a bearing arrangement to a cutting body (21). The cutting edge (23) of the cutting body (21) is arranged at a radial distance from the axis of rotation corresponding to a desired cutting circle diameter.

Abstract: A holding device for machine tool inserts includes a recess delimited by clamping jaws. The recess serves as a clamping seat for the insert. The holding device also includes a slot extending the recess and having a receptacle for a spreading body of a spreader key. The slot has a half-circular expansion on one of its edges serving as a receptacle for the spreading body. The cross section of the spreading body of the spreader key is a polygon outline in the shape of an isosceles triangle whose corners are each rounded with an equal radius of curvature.

Abstract: A holder for free-cutting machining tool inserts, especially for chiseling, piercing or cutting inserts, includes an essentially beam-like edge support (1) with a receiving pocket (5) constructed in its end for the blade edge inserts. Clamping jaws (9 and 11) define the narrow width of the receiving pocket (5). A slot (29) is configured in the blade edge support (1) forming a flexible pivot for moving one clamping jaw. An operating member (37) is provided for producing a clamping force in the area of the slot (29) on the movable clamping jaw (11). The operating member (37) is mounted in a bore (39) at some distance from the slot (29). The clamping force is transmitted to the movable clamping jaw (11) through a force transmission member (43) which is slidably guided in the blade edge support (1).
