Abstract:
The invention relates to a rotary cutting tool (1) made of multiple materials, and to a method for producing a tool of this kind, said tool comprising at least one continuous or substantially continuous cutting edge (8, 9) made of at least two different successive materials. The end or top (10) of the tool is a point eccentric in relation to the axis of rotation (5) of the tool.
Abstract:
The invention relates to a milling tool (1) for opening laser-welded connections between thin metal sheets. Said milling tool comprises a rotary drive source (2), which is used to operate a milling cutter (9). The head of the milling cutter (9) protrudes through an opening (28) in a base plate (4) that forms an even contact surface (25) for defining the penetration depth of the milling cutter head in the material. In addition, the base plate (4) is provided with a lateral contact surface or contact edge (27) that introduces the reaction force, which originates from the cutting force, directly and rapidly into a contact surface of the bodywork section that is to be treated.
Abstract:
Disclosed is a method of manufacturing an endmill tool, including detecting a crystal direction of a selected natural diamond gemstone (1) by inspecting the structure of the diamond gemstone (S100), forming a lower base surface (S20) and an upper reference surface (S230) of the diamond gemstone by using abrading equipment after welding the diamond gemstone with a first sub-body (20a, 20b, 20c), grinding (S300) an edge portion of the diamond gemstone by using grinding equipment after welding a machining tip, which is separated from the first sub-body (20a, 20b, 20c), with a second sub-body (30) to complete the machining tip having a cutting blade, and temporarily installing (S400) 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:
Fräser oder Schleifwerkzeug, hergerichtet zum Auftrennen von Schweißnähten, insbesondere von Laserschweißnähten an Karosserieblechen, umfassend ein im wesentliches kreiszylinderförmiges Schneidrad (2), das zumindest umfangseitig Schneiden aufweist oder eine Schleifscheibe, wobei auf zumindest einer Seite des Schneidrads beziehungsweise der Schleifscheibe Distanzscheiben (3a,3b) achsensymetrisch angeordnet sind, die einen kleineren Radius als den Außendurchmesser des Schneidrads (2) aufweisen.
Abstract:
The invention provides a shape member manufacturing apparatus and a shape member manufacturing method which aims at cutting and grinding a joint projection 8B formed when a plurality of shape members are joined together by welding or friction stir welding, in a short time with high accuracy. A plurality of mounts 11 having a side structure 8 placed thereon are arranged in the longitudinal direction of the side structure. A joint projection 8B of a welded portion or a friction stir welded joint is formed on the surface of the side structure 8 in its longitudinal direction. A carrier 100 travels in the longitudinal direction of the side structure 8. Columns 105 are installed in a girder 103 of the carrier, and a milling cutter device 80 and a grinding device 90 are installed in lower portions of the columns 105. A milling surface of a milling cutter 81 of the milling cutter device 80 has a circular-arc shape with a radius R. The milling cutter 81 performs cutting at an angle θ1 tilted with respect to a vertical line. Further, the milling cutter device is provided with sliding plates 85. The milling cutter device performs cutting with the sliding plates 85 brought into contact with the surfaces of the extruded shape members.
Abstract:
La présente invention a pour objet un instrument de coupe (1) de type rotatif, notamment de type fraise, destiné à un usage chirurgical ou dentaire et comprenant une partie active (2) de coupe et un manche (3). Ladite partie active (2) est en carbure métallique et le manche (3) est en alliage de nickel-titane. L'instrument comprend en outre une partie intermédiaire (4) en acier inoxydable placée entre la partie active (2) et le manche (3) et reliée métallurgiquement à ladite partie active (2) et audit manche (3).
Abstract:
A 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 (ηa, ηr) 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.
