摘要： The invention relates to a machine tool, particularly a machine reamer, comprising a shaft-type base (10) and a replaceable cutter head (12) which frontally protrudes from the base (10). An axially protruding extension (24) of said cutter head (12) engages into a frontal receptacle (14) that is fixed to the base, the cutter head (12) being removably clamped in said receptacle (14) by means of a clamping screw (34) which penetrates the replaceable cutter head (12) in a truly axial direction. The screw head (58) of the clamping screw (34) rests against a face (60) of the replaceable cutter head (12). The extension (24) of the replaceable cutter head (12) is provided with a polygonal part (26) which is complementary to a truly axial polygonal hole (25) that is fixed to the base and is penetrated by the polygonal part (26). The extension (24) is further provided with an externally conical part (28) which adjoins the polygonal part (26), engages into a conical hole (27) that is fixed to the base, and is complementary to said conical hole (27) while the clamping screw (34) is screwed into a central internal thread (38) that is fixed to the base. Preferably, the base is equipped with a functional insert (40) which is rigidly connected to the base (10) and contains the internal thread (38), the polygonal hole, and/or the conical hole (27).

摘要： The present invention provides an improvement (20) in a Davenport® automatic screw machine having a stationary spindle. The improvement broadly includes a quick-change mechanism (26) associated with the stationary spindle (22). The mechanism includes mating frusto-conical first and second surfaces (28, 31) on the spindle and tool holder, and a multi-lead threaded connection (32) between the tool holder and stationary spindle such that the tool holder may be quickly locked into mating engagement with the stationary spindle by relative rotation therebetween through a short angular distance. The invention may also include an adjustment mechanism (33) that allows the axis (X2-X2) of the tool to be aligned with the axis (X1-X1) of a spaced rotatable spindle. This adjustment mechanism includes a base member (34), an adjustment member (35), and a locking mechanism (37) for selectively holding the adjustment member in the desired position relative to the base member.

摘要： 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. The driving surfaces and the supporting surfaces are formed by limited partial surfaces (43 or 41) of the side walls (37 and 35) of the grooves (31) whose other surfaces are retracted in relation to said partial surfaces (43 and 41) with the purpose of forming a spacing between the ribs and the walls of the grooves (31).

摘要： The present invention relates to a tool coupling comprising a holder (1), an adapter (3; 3') for at least one cutting insert for chip removing machining and a separate element (5; 5') in order to detachably connect the holder (1) and the adapter (3; 3') with each other, said holder (1) being provided with a first serration (12), having mutually parallel grooves, and the adapter (3; 3') being provided with a second serration (16), having mutually parallel grooves. The invention also relates to the holder (1) and the adapter (3; 3') per se. It is significant for the tool coupling according to the present invention that the first serration (12) is located in a plane having an extension essentially perpendicular to a longitudinal centre axis (13) of the tool coupling, and that the second serration (16) is located in a plane having an extension essentially perpendicular to said longitudinal centre axis (13).

摘要： Eccentricity is not allowed to occur in a blade section, and a blade section is maintained in a stable installation state. A hook section 124, which is composed of a shaft section 125 and an end section 126 provided with a corner section 132 that protrudes as a ledge farther to the outside in the radial direction than this shaft section 125, is formed in a blade section 120. A hook hole 144, which allows the passage of end section 126 of hook section 124, is formed in a bolt section 140. Engaging sections 150 are formed around hook hole 144. Corner sections 132 of end section 126 of hook section 124 are engaged with engaging sections 150 when blade section 120 and bolt section 140 are relatively moved in the direction in which they move away from each other in the direction of an axis O in the state in which blade section 120 is rotated by about 60° towards the front in a direction of screwing rotation S with respect to bolt section 140 after inserting and passing end section 126 of hook section 124 through hook hole 144.

摘要： Die Erfindung betrifft eine Bohreinrichtung (1) zur Bearbeitung spröder Werkstoffe. Hierbei ist ein Bohrkopf (2) mit einer Bohrstange (3) zur Übertragung des Bohrmomentes lösbar mittels einer formschlüssigen Verbindung verbunden. Zur exakten relativen Ausrichtung hat der Bohrkopf (2) eine kegelförmige Ausformung (10), die im dargestellten Betriebszustand zentrisch in eine entsprechende Aufnahme (11) der Bohrstange (3) eingreift. Zum Schutz gegen axiales Lösen dient eine als Hohlmutter ausgeführtes Fixierung oder Arretierung (15; 20), welches in jeweils ein Gewinde (16) des Bohrkopfes (2) und in ein Gewinde (17) der Bohrstange (3) eingreift, wobei die Gewinde (16, 17) zueinander gegenläufige Steigungen aufweisen. Durch eine Drehbewegung der Arretierung (15) können der Bohrkopf (2) und die Bohrstange (3) daher in einfacher Weise gegeneinander verspannt oder zum Austausch auseinander gezogen werden, wobei zugleich die von der Arretierung (15) eingeschlossene Verbindung vor äußeren Einflüssen optimal geschützt ist. Die Bohreinrichtung (1) ermöglicht daher Bohrungen mit hoher Genauigkeit, ohne daß hiermit zugleich ein erhöhter Verschleiß oder eine umständliche Handhabung verbunden ist.
