20090100970 | Adapted back plate apparatus and method for improved die-cutting - A method for improving die-cutting involving first creating a back plate footprint, possessing impressions of the imperfections found in the cutting surface of a die-cutting machine. This method provides die-cutters a simple, inexpensive way to dramatically improve the alignment of die-cutting knives for making cuts. The method uses a malleable material that will readily receive an impression of imperfections of a cutting surface when some pressure is provided, but the material must also be capable of hardening into a useable solid material. The principles of this method may be applied to all die-cutting machines by making a back plate footprint of the die-cutter in question and by properly inserting it back into the chase where the impressions contained therein will press down on the material below it so as to better align the cutting knives of the die being used. | 04-23-2009 |
20090120241 | CUTTING TOOL AND ALSO A METHOD FOR THE MANUFACTURE OF A CUTTING TOOL - The invention relates to a cutting tool for the machining of wood or a wood-based material, in particular a wood composite material, or a plastic, wherein a layer system for the formation of a surface coating is present on a surface of a cutting edge of the cutting tool. An outermost surface layer of the layer system is formed from a composition of the form [Cr | 05-14-2009 |
20100011911 | METHOD FOR MANUFACTURING A CUTTING BLADE, A CUTTING BLADE AND USE OF AN AUXILIARY MATERIAL IN MANUFACTURING THEREOF - A method for manufacturing a cutting blade, which cutting blade is meant particularly to be used as a rotating cutter blade and, which is manufactured from a blade preform, being provided with a cutting surface. The blade preform includes a frame part, being made of a basic material and in which on an attachment surface, existing essentially at a cutting area of the cutting blade to be manufactured, is processed at least a wear resistant material layer that forms the cutting surface. The layer includes steel that is alloyed with tungsten or chromium and vanadium. A cutting blade, being manufactured according to the method, and use of an auxiliary material in manufacturing thereof. | 01-21-2010 |
20100043602 | Downhole Cutting Tool, Using a Single Piece Tubular with a Radially Displaceable Portion - Disclosed herein relates to a single piece tubular member. The tubular member having a non-radially displaceable portion and a radially displaceable portion, the radially displaceable portion being movable to a position of similar radial displacement as that of the non-radially displaceable portion and a position of relatively large radial displacement in comparison to the non-radially displaceable portion. The tubular member also having at least one cutting arrangement disposed at the radially displaceable portion. | 02-25-2010 |
20100154596 | SURFACE-COATED CUTTING INSERT AND METHOD FOR MANUFACTURING THE SAME - A method for manufacturing a surface-coated cutting insert that includes an insert body having a substrate of tungsten carbide-based cemented carbide, titanium carbonitride-based cermet or ceramics, a base layer, an intermediate layer and an outermost layer. The base layer and the outermost layer are made of a single layer or two or more layers formed of carbides, nitrides, oxides, or borides of one selected from the group consisting of Group IVa metals, Group Va metals, Group VIa metals, aluminum and silicon, or complex compounds thereof, and the intermediate layer is formed of primarily Al2O3. The outermost layer is removed on part of the insert body surface including the flank face and a flank face-side cutting edge portion of the intersecting edge line region, with the outermost layer being left on part of the rake face inside a boundary with the intersecting edge line region. | 06-24-2010 |
20110232422 | Scribing wheel for brittle material and manufacturing method for same, as well as scribing method, scribing apparatus and scribing tool using the same - A scribing wheel for a brittle material includes a circumferential ridgeline in which two truncated cones have connected bottoms so as to share a rotational axis. Alternating notches and protrusions are formed along the circumference ridgeline. The protrusion are portions of the ridgeline remaining after the ridgeline is notched. The length of the notches is less than that of the protrusions so that a catch on the surface is improved while lowering the high penetrability. | 09-29-2011 |
20110259150 | Disc Cutter for an Earth Boring System - In one aspect of the present invention a disc cutter for an earth boring system includes an axle and a sintered polycrystalline ceramic disc disposed about and forming a continuous perimeter around the axle. The disc cutter may be attached to a drill bit comprising a body, working face and plurality of blades. | 10-27-2011 |
20150135905 | Rotary cutting tool with helically running cutting edges and method of manufacturing such a tool - The invention relates to a rotary cutting tool ( | 05-21-2015 |
