Embodiment 1-2 and comparative example A-B

[0117] According to Test Procedure I, Examples 1-2 and Comparative Examples A-B were tested. The test results in Table 9 show that in a simulated dry in-situ grinding application on a stainless steel workpiece, abrasive articles with larger topography and larger ceramic particles compared to conventional coated abrasive articles and conventional agglomerate coated abrasive articles , improves sanding consistency and extends service life.

Embodiment 3-4 and comparative example C

[0119] Examples 3-4 and Comparative Example C were tested according to Test Procedure II using 304 stainless steel workpieces. The test results in Table 9 show that in a simulated wet surface grinding application, compared to having a larger configuration but including non-ceramic abrasive particles (Example 4), and compared to conventional coated abrasive articles, Abrasive articles with large configurations and large ceramic particles (Example 3) increased grinding speed, improved grinding consistency, and extended service life.

Abstract

A structured abrasive article, methods of making an abrasive article, and methods of using an abrasive article. The abrasive composites forming the abrasive article have a height of at least 500 micrometers, and the abrasive particles in the composites have an average particle size of at least 40 micrometers, in some embodiments, at least about 85 micrometers. The large topography composites, together with the large ceramic abrasive particles, provides an abrasive article that has a more consistent cut, a longer cutting life, and a more consistent surface finish than conventional make / coat abrasive articles with the same size and type of abrasive particles. Additionally, the large topography composites, together with the large ceramic abrasive particles, provide an abrasive article that has a more consistent cut, a longer cutting life, and a more consistent surface finish than structured abrasive articles having a smaller topography, even with the same abrasive particles.

Description

technical field [0001] The invention relates to an abrasive product, in particular to a structured abrasive product, a manufacturing method and a using method. More specifically, the structured abrasive article has a larger topography and includes large ceramic abrasive particles. Background technique [0002] Abrasive products have been used for grinding and polishing workpiece surfaces for more than 100 years. These applications range from deep grinding, high-pressure metal grinding to fine polishing of, for example, ophthalmic lenses. Typically, abrasive articles are made with a plurality of abrasive grains bonded to one another (eg, bonded abrasives or grinding wheels), or abrasive grains to a backing (eg, coated abrasives). Coated abrasives usually have a single layer of abrasive grains or sometimes two layers of abrasive grains. Once these abrasive grains are worn away, the coated abrasive is essentially ruined and can usually only be thrown away. [0003] For such...
