Abstract

Uvedený vynález se týká výroby nástrojů a zejména technologie výroby brusného nástroje a může být využit při výrobě brusných kotoučů s vybráním na rybinu, segmentů, vrtacího nástroje. Je znám způsob výroby brusného nástroje lisováním vícevrstvenné hmoty, získané prokládáním vrstev pojivá a brusných zrn v lisovací formě, která je opatřena regulovatelnou formovací komorou. Cílem uvedeného vynálezu je zvýšení kvality brusného nástroje. Uvedeného cíle se dosáhne zabezpečením poměrného překrytí brusných zrn vedlejších vrstev ve směruvlisování. Uvedený vynález umožňuje zvládnout kvalitu brusného nástroje regulováním jeho řezivosti, zabezpečením poměrného překrytí zrn vedlejších vrstev a také umožňuje optimalizovat proces orovnání brusného nástroje a získat maximální efektivnost a využití brusného zrna, protože v objemu brusné vrstvy mají zrna stanovené uspořádání.The invention relates to the production of tools and in particular to the technology of manufacturing an abrasive tool and can be used in the production of grinding wheels with a dovetail recess, segments, and drilling tools. A method of manufacturing an abrasive tool by pressing a multilayer mass obtained by interleaving layers of a binder and abrasive grains in a pressing mold, which is equipped with an adjustable molding chamber, is known. The aim of the invention is to improve the quality of the abrasive tool. The aim is achieved by ensuring the relative overlap of the abrasive grains of the secondary layers in the pressing direction. The invention makes it possible to control the quality of the abrasive tool by regulating its cutting ability, ensuring the relative overlap of the grains of the secondary layers, and also makes it possible to optimize the process of dressing the abrasive tool and obtain maximum efficiency and utilization of the abrasive grain, since the grains have a certain arrangement in the volume of the abrasive layer.
