Abstract:
Disclosed is a method of manufacturing an endmill tool, including detecting a crystal direction of a selected natural diamond gemstone by inspecting the structure of the diamond gemstone, forming a lower base surface and an upper reference surface of the diamond gemstone by using abrading equipment after welding the diamond gemstone with a first sub-body, grinding an edge portion of the diamond gemstone by using grinding equipment after welding a machining tip, which is separated from the first sub-body, with a second sub-body to complete the machining tip having a cutting blade, and temporarily installing the machining tip, which is separated from the second sub-body, in a super hard body installed in setting equipment, adjusting an alignment state of the machining tip, and bonding the machining tip with the super hard body by using a normal-temperature bonding agent through a normal-temperature coagulation scheme to complete the endmill tool.
Abstract:
A method of forming integrally bladed rotors for gas turbines is described. The method includes drilling in a workpiece material recesses defining flow passages and rotor blades, performing a coarse milling step to refine surfaces of the rotor blades, and filling the recesses between the rotor blades with a damping material, thus encasing the rotor blades in the damping material. The method further includes performing a finishing milling step to remove the damping material and the workpiece material on surfaces of the rotor blades, while maximizing a damping effect of the damping material on the rotor blades. To maximize the damping effect, the finishing milling tool moves along a path that preferentially mills one surface of a blade while the other surface is in contact with the damping material.
Abstract:
A blank holder and a blank are provided, the blank holder having a receiving area for a substantially disc-shaped blank, the receiving area being curved. The receiving area forms a straight, circular or part-circular or arc-shaped form-fitting profile. The blank has a matching guide shell which can be inserted or turned into the form-fitting profile.
Abstract:
According to the invention a tool system for machining a workpiece is recommended, having a cylinder-shaped retaining shank (12) that has a cutting head holder (16) on an end surface (14) facing the workpiece, a drive mount (20) on an end surface facing the drive (18), a cutting head (22) having at least one cutting edge (24), a cutting head hub (26) corresponding to the cutting head holder (16) on the retaining shank (12), a tool coupling (28) with a tool interface (30), and a coupling hub corresponding to the drive mount (20), wherein the coupling hub (32) and/or the cutting head hub (26) have elevated areas (34, 50) with contact surfaces (36, 52), wherein the elevated areas (34, 50) are distributed in an arrangement in both the circumferential (38) and longitudinal directions of the coupling hub (32) and/or the cutting head hub (26), wherein the contact surfaces (36, 52) make contact on support surfaces (42, 56) on the drive mount (20) and/or on the cutting head holder (16) on the retaining shank (12), and wherein the drive mount (20) and/or the cutting head holder (16) is permanently connected to the coupling hub (32) and/or the cutting head hub (26) by means of a joining material (46) in intermediate spaces (44, 58) between the elevations (34, 50).
Abstract:
The invention relates to a cassette for a milling cutter having a cutter carrier and a clamping part, which together constitute a generally rectangular cassette, the cutter carrier and the clamping part being loosely placed on each other and together delimiting a fastening opening for a fastening screw by means of which the cassette can be fastened in a receiver of a milling cutter, the cutter carrier having a seat for a cutting insert. The invention additionally relates to a milling cutter having at least one receiver for a cassette and having at least one such cassette. A gap, S, between the cutter carrier and the clamping part is located below the cutting tip of the cutting insert to prevent chips from being lodged in the gap, S.
Abstract:
Milling cutter (1), which can rotate about a cutter longitudinal axis (A), comprises a sleeve-shaped shaft (2) provided with an inner lying chip evacuation channel (11), which is arranged, in essence, symmetric to the cutter longitudinal axis (A), and with a suction opening (12). The milling cutter also comprises a milling head (3, 3a, 3b, 3c), which is held coaxial to the cutter longitudinal axis (A) and to the shaft (2) while being held on said shaft and which comprises, as cutting edges (7, 9), a face cutting edge (7) and a peripheral cutting edge (9). At least one cutting edge (7, 9) forms a positive rake angle (γa, γr) on the periphery of the milling head (3, 3a, 3b, 3c). The milling cutter (1) is particularly suited for machining light metals, especially for circular milling. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, possibly following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Abstract:
An end milling cutter for heat-resistant superalloys (HRSA) has a shank and a cutting head, which have a common rotation axis, the shank having a connection section for connection to the cutting head and a coupling section for connection to a tool holder, the cutting head consisting of a solid ceramic part, which has a rotationally symmetrical envelope and is butt-joined to an end face of the connection section. In order to keep excessive vibrations and thus stresses low in the interface between the cutting head and the connection section of the milling cutter and to create milling cutters that can also cover the diameter range above 12 mm and in particular above 20 mm and up to 32 mm, the coupling section has a conical peg having an external thread.
