A system and method for producing an abrasive article includes a production tool configured to provide shaped abrasive particles to a resin coated backing. A first end and a second end of the production tool are spliced together to form a spliced area. The production tool includes a dispensing surface that includes a plurality of cavities formed between the first end and the second end and configured to receive and hold the shaped abrasive particles. The resin coated backing is configured to receive the shaped abrasive particles from the dispensing surface of the production tool and configured to receive further shaped abrasive particles to fill gaps in the shaped abrasive particles caused by an absence of the plurality of cavities in the spliced area.

Shaped ceramic abrasive particles include a first surface having a perimeter having a perimeter comprising at least first and second edges. A first region of the perimeter includes the second edge and extends inwardly and terminates at two corners defining first and second acute interior angles. The perimeter has at most four corners that define acute interior angles. A second surface is disposed opposite, and not contacting, the first surface. A peripheral surface is disposed between and connects the first and second surfaces. The peripheral surface has a first predetermined shape. Methods of making the shaped ceramic abrasive particles, and abrasive articles including them are also disclosed.

The disclosure relates to a curable composition comprising: a polymerizable epoxy-acrylate resin composition having a complex viscosity at 25? C. and 1 Hz frequency of at least about 4500 Pa-s and a probe tack peak force of at least about 300 kPa; and abrasive particles partially or fully embedded in the polymerizable epoxy-acrylate resin composition. The disclosure also relates to cured compositions formed from such curable compositions, wherein the abrasive particles are partially or fully embedded in the cured composition. In addition, the disclosure relates to abrasive articles made from such cured compositions as well as methods for making abrasive articles.

Various embodiments disclosed relate to an abrasive article. The abrasive article includes a nonwoven web. The nonwoven web includes a first irregular major surface and an opposite second irregular major surface. The nonwoven web further includes a fiber component comprising staple fibers having a linear density ranging from about 50 denier to about 2000 denier and a crimp index value ranging from about 15% to about 60%. The nonwoven web further includes a binder dispensed on the fiber component and abrasive particles dispersed throughout the nonwoven web.

An abrasive belt is provided which comprises a textile fabric being formed of interconnected yarns, and a coherent abrasive area formed on one side of the textile fabric, wherein the abrasive belt further comprises a plurality of regularly distributed openings in the form of through holes. The abrasive belt allows for a homogenous distribution of the abrasive material and thus an even sanding finish as well as for an appropriate dust removal and appropriate mechanical properties.

Metal bond abrasive articles and methods of making metal bond abrasive articles via a focused beam are disclosed. In an aspect, a metal bond abrasive article includes a metallic binder material having abrasive particles retained therein, where the abrasive particles have at least one coating disposed thereon. The coating includes a metal, a metal oxide, a metal carbide, a metal nitride, a metalloid, or combinations thereof, and the at least one coating has an average thickness of 0.5 micrometers or greater. The metal bond abrasive article includes a number of layers directly bonded to each other. Metal bond abrasive articles prepared by the method can include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a metal bond abrasive article; and generating, with the manufacturing device by an additive manufacturing process, the metal bond abrasive article based on the digital object. A system is also provided, including a display that displays a 3D model of a metal bond abrasive article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the metal bond abrasive article.

The method generally involves the steps of filling the cavities in a production tool each with an individual abrasive particle. Aligning a filled production tool and a resin coated backing for transfer of the abrasive particles to the resin coated backing. Transferring the abrasive particles from the cavities onto the resin coated backing and removing the production tool from the aligned position with the resin coated backing. Thereafter the resin layer is cured, a size coat is applied and cured and the coated abrasive article is converted to sheet, disk, or belt form by suitable converting equipment.

An abrasive article including a body including abrasive particles contained within a bond material, a first major surface, a second major surface, and a side surface extending between the first major surface and second major surface, and a coating overlying at least a portion of one of the first major surface or the second major surface. In an embodiment, the coating comprises at least one element selected from the group of chromium, nickel, carbon, nitrogen, tungsten, sulfur, molybdenum, iron, zinc, silicon, titanium, aluminum, zirconium, magnesium, zinc, boron, cobalt, calcium, or any combination thereof. In another embodiment, the coating comprises a cermet, a ceramic, or a combination thereof.
