Abstract: A device for abrasive machining, comprising a substantially cup shaped to rough rotatable around an axis and having an inner chamber and a disk-shaped to working element at its one axial end; and immovable holder attachable to a machine to and surrounding at least a portion of said working element at an opposite axial end at a distance therebetween so as to form a passage for passing a cooling liquid; and a helical guiding means provided in said passage so that during rotation of said tool inside said holder the cooling liquid is supplied through the substantially helical guide into said inner chamber of said tool toward said working element.

Abstract: A method of producing abrasive tools with abrasive particles consisting of Al2O3 has the steps of producing a mixture of initial components with particles of Al(OH)3, forming blanks of an abrasive tool from the mixture of the initial components with the particles of AL(OH)3, subsequently producing the abrasive tools with the abrasive particles of Al2O3 by subjecting the blanks to a heat treatment such that the particles of Al(OH)3 are converted into the abrasive particles of Al2O3 in the tools, wherein the forming includes rolling a sheet from the mixture of the initial components with the particles of Al(OH)3 before the heat treatment and conversion of the particles of Al(OH)3 the abrasive particles of Al2O3 which particles of Al(OH)3 are softer than the abrasive particles of Al2O3 and therefore do not damage a rolling equipment, and thereafter separating the blanks of the abrasive tools from the sheet for the subjecting to the heat treatment.
