20090029628 | Abrasive products with splice marks and automated splice detection - A coated abrasive product, comprising a first section and a second section, the first and the second sections being continuously joined together by a splice. The first section includes at least one first splice mark adjacent to the splice, wherein the first splice mark is a marking or a cluster of markings. A method of processing an article with such a coated abrasive product, and a method of acquiring information of such a coated abrasive product, respectively, includes detecting at least one characteristic of at least one first splice mark of the first section of the abrasive product, and comparing the detected characteristic to a database, wherein the detected characteristic of the first splice mark conveys approach of the splice and the end of the first section. The method of processing an article further includes providing a signal to skip the splice to thereby prevent the article being processed with splice area of the abrasive product. A method of preparing such a coated abrasive product includes forming the first and the second sections of the abrasive product. | 01-29-2009 |
20090017736 | SINGLE-USE EDGING WHEEL FOR FINISHING GLASS - A single-use grinding tool includes a wheel portion having a profiled recess (e.g., such as a U, V, or bowl shape) extending circumferentially along the wheel portion's periphery. A multi-layered bonded abrasive (e.g., 3-dimensional matrix of abrasive grains and bond material, or multiple layers of abrasive tape) is conformably coated or otherwise applied in a uniform thickness along the profiled recess. The bonded abrasive in one particular case includes a metal bond with diamonds. However, organic, resinous, vitrified, and hybrid bonds, as well as other abrasive grit types, can be used. The wheel portion is supported by an arbor portion which may be removably coupled to the wheel portion, or formed integrally with the wheel portion. The tool is useful, for example, in edge grinding a workpiece, such as sheet glass. Methods of tool use and tool manufacture are disclosed as well. | 01-15-2009 |
20080250725 | Pulpstone for Long Fiber Pulp Production - Pulp production techniques are disclosed. In one embodiment, pulpstone segments are provided, that include proppant grits in the place of some or all of the conventional abrasive typically used in pulpstone applications. The proppant or proppant-abrasive mixture can be combined into a three-dimensional matrix supported by a vitrified bond. Alternative embodiments use proppant grits in an organic bond or a metal bond or a cement bond (each of which may also include abrasive grits in addition to proppant grits). The proportion of proppant grits to abrasive grits can be varied to produce pulp of varying fiber length distribution as required by the end-user (e.g., paper mill). The greater the proppant concentration, the less cutting of the fibers by the conventional abrasive will occur, producing a greater percentage content of longer fibers. Such pulp produces higher quality paper. | 10-16-2008 |
20080222967 | BONDED ABRASIVE ARTICLE AND METHOD OF MAKING - A bonded abrasive article is provided that includes abrasive grains within a bond matrix, the abrasive grains including cubic boron nitride (cBN) and the bond matrix including a polycrystalline ceramic phase. The bonded abrasive may have a Modulus of Rupture (MOR) of not less than about 40 MPa. Certain embodiments may have porosity, such as greater than about 5.0 vol %. | 09-18-2008 |
20080222965 | BONDED ABRASIVE ARTICLE AND METHOD OF MAKING - A bonded abrasive article is provided which includes abrasive grains made of cubic boron nitride within a bond matrix including a silicate. The bonded abrasive further includes a reaction product at the interface between the abrasive grains and bond matrix comprising a transition metal nitride. | 09-18-2008 |
