摘要:
A method of making an abrasive product includes compacting a cohesive layer of abrasive particles and particulate curable binder precursor prior to forming curable shaped structures, and then at least partially curing the curable binder precursor.
摘要:
Abrasive articles (e.g., abrasive wheels) comprised of abrasive particles (26) and polymeric material (24) such as a polymeric reaction product of components comprising saturated polyol, saturated polyisocyanate, and a free radical source, and methods of making and using the abrasive articles.
摘要:
Fixed abrasive articles comprising a substrate having an abrasive surface and an attachment surface, and at least one engaging projection are described. Generally, the engaging projection comprises a top surface having a top surface edge and an attachment end attached to the attachment surface of the substrate. The area of attachment between the attachment end and the attachment surface is bounded by an attachment perimeter. The engaging projection also comprises a mantle surface extending from the top surface edge to the attachment perimeter. At least one profile of the mantle surface is substantially convex from a point of maximum width along the profile to the attachment perimeter.

摘要:
A method of making shaped ceramic abrasive particles includes cutting a layer of ceramic precursor material using a laser beam and forming shaped ceramic precursor particles. Further thermal processing provides shaped ceramic abrasive particles. Shaped ceramic abrasive particles producible by the methods and abrasive articles containing them are also disclosed.

摘要:
The present invention relates to a shaped abrasive particles comprising a first side 38, a second side 40, and a sidewall 54 connecting the first side 38 to the second side 40, the particles comprising a generally triangular shape; the sidewall 54 comprising a first portion 56 intersecting the first side 38 and a second portion 58 intersecting the second side 40, wherein the slope of the first portion 56 is greater than the slope of the second portion 58.
摘要:
Shaped ceramic articles can be obtained by screen printing the desired shapes from a dispersion of a precursor of the ceramic onto a receiving surface using a transfer assisted technique that applies a differential pressure, at least partially drying the screen printed shapes, and firing them to generate the shaped ceramic articles. Shaped abrasive particles made using lower viscosity sol gels that tended to flow or creep after the screen printing formation were found to have higher grinding performance over screen printed shaped abrasive particles made with higher viscosity sol gels.
