20090123244 | Machine Tool - The invention relates to a machine tool, particularly a machine reamer, comprising a shaft-type base and a replaceable cutter head which frontally protrudes from the base. An axially protruding extension of said cutter head engages into a frontal receptacle that is fixed to the base, the cutter head being removably clamped in said receptacle by means of a clamping screw which penetrates the replaceable cutter head in a truly axial direction. The screw head of the clamping screw rests against a face of the replaceable cutter head. The extension of the replaceable cutter head is provided with a polygonal part which is complementary to a truly axial polygonal hole that is fixed to the base and is penetrated by the polygonal part. The extension is further provided with an externally conical part which adjoins the polygonal part, engages into a conical hole that is fixed to the base, and is complementary to said conical hole while the clamping screw is screwed into a central internal thread that is fixed to the base. Preferably, the base is equipped with a functional insert which is rigidly connected to the base and contains the internal thread, the polygonal hole, and/or the conical hole. | 05-14-2009 |

20100183384 | Machine tool and cutting ring for a machine tool - The invention relates to a machine tool for use in tool machines, comprising a cutting element which is preferably configured as a cutting ring and at least two insert seats that are provided in the cutting element at distance to each other in the circumferential direction. The insert seats are fitted with at least one group of at least two identical insert tips that are detachably arranged therein and that have one working edge each, the effective working edges of the insert tips of one group being cut to the same nominal size. The insert tips are configured as indexable inserts, every single indexable insert of a group being associated with a defined insert seat in all possible positions of adjustment, and the indexable inserts of a group having at least two working edges each, one of these edges being always in the effective and at least one other edge being in the ineffective position, depending on the position of the indexable inserts in the associated insert seats. The indexable inserts of a group assume identical positions of adjustment in which defined working edges of every indexable insert of a group have the same orientation in the associated insert seat, the working edges of the indexable inserts of a group being cut to a nominal size in all common positions of adjustment. | 07-22-2010 |
20120200050 | JUNCTION BETWEEN TWO COMPONENTS OF A ROTATING TOOL SYSTEM - A junction between two components of a tool system, that rotates about an axis of rotation, includes a conical seat, on the first component, coaxial to the axis of rotation and which is defined by an annular front face. The second component carries a coupling having a conical surface complementary to the conical seat and an annular end face resting against the front face. A tie bolt axially projects beyond the free end of the coupling pin and engages, in a cavity adjacent to the seat. The junction also has tensioning elements that are actuated from the exterior for mutually bracing the components, which are radially guided in the first component, and which act upon the tie bolt and are functionally linked with joint actuating means for adjustment between detached and tensioned positions. The tensioning elements include ejection portions that can be fitted with a rotatably received rolling element. | 08-09-2012 |
