摘要:
Radius mill and cutting work method that includes a plurality of end cutting edges arrayed around a central axis O and a plurality of arc-shaped radius end cutting edges continuous with the end cutting edges on an outer peripheral side in a radial direction. The end cutting edge is divided into an inner peripheral side end cutting edge and an outer peripheral side end cutting edge in a radial direction. Second surfaces of the plurality of inner peripheral side end cutting edges are coupled at a part close to the axis O. A region of coupled second surfaces is continuous from a region including the axis O to outer peripheral sides of respective inner peripheral side end cutting edges in a radial direction in a strip shape. A width of the strip-shaped region gradually enlarges from axis O side to an outer peripheral side in a radial direction.

The invention relates to a cutter support (11) for fastening to a cutter head, comprising a shaft-like pin (11) and a head, having a soldered-in cutter (12) with a minor cutting edge formed by a face (27) and a free surface (28). According to the invention the minor cutting edge has a rounded area (25), the radius of which continuously increases from a minor cutting edge end (25a) at least to the cutting edge center, or to the other minor cutting edge end (25b).

An end mill is provided having an axis of rotation, a shank section and a fluted section, each extending along the axis of rotation, and a plurality of helical teeth. The fluted section has a first end attached to the shank section and a second end. The plurality of helical teeth is disposed within the fluted section. Each helical tooth has a cutting edge, a relief surface, a cutting surface, and an edge preparation surface. The edge preparation surface is contiguous with the cutting edge of the respective tooth.

A face cutter for machining fibre-reinforced materials such as carbon-fibre-reinforced plastics, glass-fibre-reinforced plastics or plastics reinforced with polyester threads is provided which includes main flutes, which form with trailing premachining lands a cutting wedges with premachining cutting edges, and auxiliary flutes, the number of which corresponds to a number of the main flutes, each trail one of the main flutes in the peripheral sense, each distance in the peripheral sense a postmachining land from the pre-machining land leading in the peripheral sense, and form with the postmachining land a cutting wedge with a postmachining cutting edge. The premachining cutting edges extend alternately with left-hand twist about and untwisted along the tool axis, the postmachining cutting edges trailing the left-hand twisted premachining cutting edges extend untwisted along the tool axis, and the postmachining cutting edges trailing the untwisted premachining cutting edges extend with a left-hand twist about the tool axis.
摘要:
A milling cutter for milling a groove into a blade footing of a turbine blade made from a superalloy. The milling cutter comprises a shaft part and a cutting part connected to the shaft part in the longitudinal direction. The cutting part has flutes and, when viewed in cross section perpendicular to the longitudinal direction, has several cutting teeth distributed about the periphery. The cutting teeth are designed as scraping teeth with negative cutting geometry.
摘要:
A diamond-coated tool including: (a) a substrate; and (b) a diamond coating disposed on the substrate. The diamond coating is formed of diamond crystals grown on the substrate. Each of the diamond crystals has a diameter not larger than 2 nullm as measured on an outer surface of the diamond coating, and/or a length not larger than 2 nullm as measured in a direction in which each of the grown diamond crystals has expanded by its growth. The diamond coating preferably consists of a plurality of layers.
