A tool insert for the production of an object by an injection molding method, wherein the injection molding tool includes an insert frame and at least one lamination assembly having a plurality of individual laminations, wherein the at least one lamination assembly is inserted in the insert frame. In further aspects, the invention relates to a method and a system for producing an object having curved surfaces using the tool insert, and to an object which can be produced with the method. The system for producing an object comprises a tool insert and a sliding element. A basic idea of the invention is that curved surfaces can be introduced into the object in that the insert frame has curved surfaces and/or at least one distortion cushion is arranged between the insert frame and the at least one lamination assembly.

This invention relates to abrasive flap discs that include wearable backing plates and methods of making and using such abrasive flap discs and wearable backing plates. The claimed articles, processes, and systems related to the use and manufacturing of such abrasive articles are improved in performance and cost effectiveness.

An abrasive member includes an abrasive member base and a plurality of abrasive particles applied to the abrasive member base. At least a large proportion of the abrasive particles form an abrasive edge unit with an abrasive edge inclined at an angle between 0 and 90 relative to a defined working direction.

A cutting element includes a substrate and a cutting layer disposed on a surface of the substrate. The cutting layer includes an ultra hard material. The substrate includes tungsten carbide and a metal binder. The substrate has a magnetic saturation value in the range of from 80 to less than 85%. In another aspect, the magnetic saturation value may increase within the substrate along a gradient, wherein proximal to the interface with the cutting layer, the substrate has a magnetic saturation value in the range of from 80 to less than 85%. Drill bits incorporating such cutting elements and methods of manufacturing such cutting elements are described.

A grinding plate for a grinding disk of a grinding machine, wherein the grinding plate has a basic body and a Velcro hook layer with Velcro hooks. The basic body of the grinding plate includes a fiber-reinforced plastic and the Velcro hook layer comprises a nonreinforced plastic. A method for producing such a grinding plate is also provided. The Velcro hook layer can be molded as a thin layer of nonreinforced plastic onto the basic body made of a fiber-reinforced plastic. The grinding plate can be produced in particular in a two-component injection molding method.

This invention relates to compressed composite backing materials (e.g., compressed polymer impregnated backing substrates) and coated abrasive articles that include such compressed composite backing materials. This invention also relates to methods of making and using said compressed composite backing materials and coated abrasive articles. The claimed processes and systems related to the use and manufacturing of coated abrasive articles are improved and cost effective.

A fixed abrasive article having a body including abrasive particles contained within a bond material, the abrasive particles including shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined position or a predetermined three-axis orientation, including a placement angle ranging from +90 degrees to 90 degrees and a rake angle ranging from +90 degrees to 90 degrees.

An abrasive tool can include a bonded abrasive including a body and a barrier layer bonded to a major surface of the body. The body can include abrasive particles contained within a bond material. The barrier material can include a metal-containing film. In an embodiment, the barrier layer may further include a polymer-containing film. In another embodiment, the barrier layer may include a biaxially oriented material. The abrasive tool may be formed such that the barrier layer is formed in-situ with the formation of the bonded abrasive.

A grinding tool includes a substrate having a surface provided with a plurality of openings, and a plurality of grinding studs. Each of the grinding studs includes a stud portion and an abrasive particle attached to each other, the stud portions being respectively attached into the openings, and the abrasive particles protruding outward from the surface, each of the abrasive particles having a pattern cut across a tip thereof to define multiple apexes adjacent to one another.
