Abstract (en)

[origin: WO2018149483A1] In a method for producing a grinding tool, a tool base body (4) is provided that forms a three-dimensional adhesive surface (24) by application of a binder (23). The tool base body (4) is positioned such that the adhesive surface (24) is arranged in an electrostatic field (E) between a first electrode (5) and a second electrode (6). Abrasive grains (8, 9) are introduced into the electrostatic field (E), which abrasive grains move, as a result of the electrostatic field (E), to the adhesive surface (24) and adhere there. The grinding tool produced in this way has a three-dimensional abrasive grain layer (25). The production of the grinding tool is simple, flexible and economical. The grinding tool has an abrasive grain layer (25) of any shape and can be used in a wide range of applications with a high cutting performance and a long service life.
