Abstract:
A tool coupling arrangement for drills and reamers includes tool and shank portions with respective tool and shank axial stoppers. An at least partially cylindrical tool coupling end of the tool portion is located within a longitudinal through forward bore portion in the shank portion, and being coupled therein via an elongated coupling member located further inwards in the shank portion and comprising axially opposite member coupling and pulling ends. The forward bore portion has front and rear sub-portions and a bore recess which is located therebetween and extends radially outwardly. In a locked position, the tool axial stopper abuts the shank axial stopper. The tool coupling end abuts the front and rear sub-portions. And the member coupling end is wedged between the tool coupling end and the bore recess.
Abstract:
The invention relates to a cutting tool (10, 40, 54), especially a friction tool, milling tool or drilling tool, with at least one cutting insert (14, 42, 56) fastened on a tool body (12) and comprising at least one free surface or at least one round, beveled surface and preferably comprising at least one free surface, preferably consisting of polycrystalline diamond (PCD) or cubic boron nitride (CBN). In order to improve the cooling, the removal of chips and the lubrication of the at least one cutting insert, it is provided that a coolant conduit (30) run through the tool body (12) forms a connection to at least one coolant conduit section (32, 34, 72) worked into the cutting insert (14, 42, 56) and with at least one mouth opening (36, 70, 76) in the round, beveled surface (60) and/or free surface (24, 44, 62) of the cutting insert (14, 42, 56).
Abstract:
The invention relates to a reaming tool, comprising a rotationally drivable main body (16) and at least one cutting body (18) fastened thereto. The at least one cutting body has at least one reaming blade (26) at the edge of a rake face (28). According to the invention, a chip-forming step (32) and/or chip-breaking elements (34) are formed in the rake face (28) and the reaming blade (26) has a ground cutting edge (40, 42, 44).
Abstract:
A screwdriver includes a handle, a screwdriver head coupled to the handle, and a conduit reamer coupled to the handle. The conduit reamer includes a first cylindrical portion having a first sidewall with a first diameter, and a second cylindrical portion positioned partially within and extending out of the first cylindrical portion. The second cylindrical portion has a second sidewall with a second diameter. The second diameter is smaller than the first diameter such that a gap is formed between the first and second sidewalls. The conduit reamer also includes a blade having a reaming edge positioned in the gap between the first and second sidewalls.
Abstract:
The invention relates to a tool (1) for machining workpieces, having a base body (3), at least one geometrically defined culling edge (15, 17) on which a face (21) abuts, a chip space (47, 53) associated with the cutting edge for receiving the chips removed by the cutting edge (15, 17), and a chip guide element (27, 29) associated with the cutting edge (15, 17). The tool is characterized in that the cutting edge (15, 17) together with the chip guide element (27, 29) forms a receiving gap (43, 45) which merges into the chip space (47, 53) and into which the chips removed by the cutting edge (15, 17) are introduced, and the chip guide element (27, 29) has a guide surface (39, 41) which, together with the face (21), forms a receiving channel (51) which abuts the receiving gap (43, 45).
Abstract:
A cutting tool including a basic body and a plurality of cutting inserts arranged in series one after the other. Each insert includes a topside, an underside, two opposite side surfaces, front and rear ends, and a cutting edge adjacent to the front end. The rear end of a first cutting insert faces the front end of a second cutting insert disposed rearward of the first insert, and a chip space forward of the cutting edge of the second cutting insert is delimited by a chip-forming surface extending in the forward direction from the rear end of the first cutting insert, and a chip-forming surface extending downward from the cutting edge of the second cutting insert.
Abstract:
An interface between two parts of a tool system is proposed, in particular of a metalworking tool (1), having a holder (3) with a recess (31) and a replaceable head (5) disposed in axial continuation to the holder (3) including an extension (33) which can be inserted into the recess (31), and having a clamping device (19) to attach the replaceable head (5) to the holder (3). The clamping device is characterized by the clamping device (19) having a pull stud (41) and an eccentric cam (21) which displaces same in the axial direction, where the eccentric cam (21) can be actuated by way of a peripheral surface (17) of the metalworking tool (1).
Abstract:
A tool for the precision machining of surfaces in workpieces comprising at least two cutter inserts in the periphery of the tool body and each having at least one defined cutting edge. The cutter inserts are of different materials at least in the region of the at least one cutting edge. Guide strips on the tool body periphery between the cutter inserts guide the tool body.
Abstract:
A multi or single cutter reaming tool has a shaft and a shaped head with at least one cutter. The shaped head is produced from a blank having a base body of a base material on its envelope surface with at least one rectilinear or helical groove-shaped recess running around it, into which high hardness cutting material is sintered. The high hardness cutting material includes at least one cutter having cutting surfaces formed by the introduction of a chip groove by a grinding wheel into the base body and movement of the grinding wheel toward the high hardness cutting material.
