The drill bit has a coupling part, which can be coupled with a coupling receptacle on the face of the base and has at least two convexly curved centring portions, which are arranged such that they are distributed over the circumference and engage with an exact fit in complementary concavely curved centring portions of the coupling receptacle. The coupling part has a complementary driver stop, meshing with a rotary driver of the coupling receptacle. It is claimed as novel that the centring portions of the coupling part and/or of the coupling receptacle have clamping surfaces, which run onto each other in the manner of a rotary wedge until the driver stop and the rotary driver come up against each other counter to a predetermined direction of rotation.
The invention relates to a cutting tool setting system (100) comprising a tool head (50) for the settable holding of a cutting tool, said head comprising an adjustment device (55) for the cutting tool (56). The cutting tool setting system (100) comprises a setting tool (10) which can be mechanically removably engaged in the tool head (50) at an interface (52) for adjusting the adjustment device (54) in the tool head (50). The setting tool (10) comprises a shaft body (12) having a key part (26). A key engagement (58) for actuating the adjustment device (55) is designed on the tool head (50). The key part (26) can be displaced relative to the shaft body (12) in the direction of the longitudinal axis (32) of said body in order to selectively couple and release the key part (26) of the setting tool (10) and the key part (58) at the interface (52) of the tool head (50).
The main body (12) of a machine tool (10) comprises a plate seat (18) having a plate element (16) arranged thereon. The plate element (16) has at least one plate edge (38), which protrudes freely to the outside over the plate seat (18) and rests against a bottom support surface of the plate seat (18). The plate element (16) can be fixed to the plate seat (18) by way of a bolt (20) extending through a bore hole in the plate element (16). A first brace (22) for the plate element (16) is provided on the plate seat (18), said brace having a support surface (34) against which the plate element (16) rests non-positively with a lateral plate surface. A further brace (24) is designed on the plate seat (18) for a lateral plate surface of the plate element (16) to rest against non-positively. In order to adjust the plate edge (38) of the plate element (16), an adjustment device (30) is associated with at least one brace (22) and enables the brace (22) to be raised and lowered with respect to the bottom support surface of the plate seat (18). A linear guide (50) is provided for said at least one brace (22), said guide absorbing the forces and torque occurring during the adjustment of the plate element (16) and introducing them into the main body (12) of the machine tool (10).
A drilling tool for machine tools has a drill body and a cutting head arranged on the front face of the drill body. The drill body has at least two chip flutes, which are delimited at their flanks by ribs and at least one of which is spirally curved. Arranged in the ribs of the drill body are coolant channels, which have an outlet opening at the end of the drill body on the cutting head side. A special feature is that the outlet openings are arranged within each one of the chip flutes and communicate with one of the coolant channels arranged in the ribs by way of a straight channel endpiece.
The invention relates to a machining center for work piece machining. The machining center comprises a machine frame (12), a machine spindle (10) driven by a motor and rotatably arranged on the machine frame (12), and a group of machine tools (18) that can be exchanged on the machine spindle. The machine tools comprise a coupling shaft (16) that is compatible with a holder (14) of the machine spindle. Furthermore, a rotary transmitter (22) for electric energy is provided, having a stator (24) fixed to the machine in a stationary manner and a rotor (26) rotating along with the machine spindle (10). It is claimed as novel that the rotary transmitter (22) comprises at least two transmission paths for electric energy which can be selected according to the electric power to be transmitted and the rotational speed of the spindle to be set and which can be activated in the coupled state of the machine tool (18). At least one first transmission path between the stator and rotor is designed in a non-contact way, while at least one second transmission path between the stator (24) and rotor (26) is provided with contacting contacts. With said measures, complete machining of the workpieces can be made possible when clamped in the machining center.
The thread former is used for the non-cutting shaping of threads and has a main body (1') on which the moldings (6) are provided, distributed over the circumference. Said moldings are provided with thread-forming teeth (13, 14). Profile grinding tools are used to produce the thread-forming teeth (13, 14), both in the main body (1') as well as in the moldings (6). In order for the thread former to be produced easily and cost-effectively, the moldings (6) protrude radially beyond the main body (1') so far that the profile tool only engages with the molding when producing the thread-forming teeth (13, 14). Consequently, the profiling tool only has to machine one type of material. The thread former is used for the non-cutting shaping of threads, particularly of internal threads.
The invention relates to a machine tool with an adjustable cutting plate. The rotating machine tool substantially comprises a base member (12) with a rotating axis (10), at least one pocket (24) formed in the base member (12) and at least one blade support (20) holding a cutting plate (18). Two side surfaces (30, 32) of the blade support (20) sit against a side support surface (34, 36), respectively, said blade support side surfaces making an angle between them, and the base (38) of the blade support sits against a base support surface (40) of the pocket (24), the blade support being clamped in the pocket removably by way of a clamp element (28). The cutting plate (18) protrudes over the blade support (20) with an effective blade (23) and over the base member (12) outward. In order to enable a fine-adjustment of tangential cutting plates in the base member, it is proposed that the base support surface (40) form a wedge surface that includes an acute angle together with a shift axis (56), said wedge surface disposed at an adjusting member (58) that can shift relative to the base member (12) along said shift axis (56), the base (38) of said blade support (20), in the shape of a complementary wedge, abutting against said wedge surface. Also, the two side support surfaces (34, 36) form guide surfaces for the blade support (20) that are directed substantially perpendicular relative to the shift axis (56) of the adjusting member (58) when said blade support (20) makes a shifting motion by way of a shifting of the adjusting member (58).
The invention relates to a shaft tool for machine tools, comprising a shaft (10), a tool head disposed at a shaft end and equipped with at least one cutting element (12), and comprising a coupling element (16) disposed at the other shaft end for direct or indirect connection to a machine spindle. A unique feature of the invention is that the shaft (10) comprises a peripheral groove (18) that extends along the circumference of the shaft and is open radially, and at least one spreading element (20) that engages in the peripheral groove and can be radially adjusted therein, resulting in the exertion of spreading and bending forced onto the groove flanks (24', 24''). The peripheral groove (18) is filled with a filler material (32) at least in the area of the spreading element (20), the filler material having both a sealing function against contaminants and a damping function. The filler material (32) also acts as a rotation prevention for the spreading elements.
The invention relates to a rotating cutting tool, in particular a boring tool for use in machine tools. The cutting tool comprises at least one cutting insert (16'), designed as an indexable insert, that has an active main blade (26) located near a corner (25) of the insert, the outer end (28) of said blade defining a circular flight path radius (R) as the blade rotates, said blade penetrating into a work piece (32) at a pre-determined cutting depth (t) near a pre-formed round hole (30).
