Abstract

Изобретение касаетс  изготовлени  абразивного инструмента. Цель изобретени  - упрощение технологического процесса путем обеспечени  ориентировани  абразивных зерен металлизации. Устройство дл  реализации способа выполнено в виде корпуса, в полость которого помещены кольцевой сборный электромагнит и ферромагнитна  жидкость с включением абразивных зерен, предварительно покрытых пленкой кле . За счет разной напр женности магнитного пол  у центрально расположенного магнита и на периферии корпуса зерна перемещаютс  к периферии корпуса, где и склеиваютс  между собой. При этом за счет воздействи  на зерна цепочек из ферромагнитных частиц, построившихс  вдоль магнитных силовых линий, они ориентируютс  вдоль пол  и, склеива сь, образуют рабочий слой абразивного инструмента из ориентированных зерен без необходимости их предварительной металлизации. После полимеризации кле  магнитную систему из инструмента удал ют и жидкость сливают. 2 ил.The invention relates to the manufacture of an abrasive tool. The purpose of the invention is to simplify the process by providing orientation of the abrasive metallization grains. The device for implementing the method is made in the form of a housing, in the cavity of which an annular collecting electromagnet and a ferromagnetic liquid are placed with the inclusion of abrasive grains previously covered with a film of glue. Due to the different intensity of the magnetic field at the centrally located magnet and on the periphery of the body of the grain are moved to the periphery of the body, where they are glued together. At the same time, by acting on the grains of chains of ferromagnetic particles built along magnetic lines of force, they are oriented along the floor and, glued together, form a working layer of an abrasive tool of oriented grains without the need for their preliminary metallization. After polymerization, the glue magnet system is removed from the tool and the liquid is drained. 2 Il.

Description

Изобретение относитс  к области изготовлени  абразивного инструмента.The invention relates to the manufacture of an abrasive tool.

Цель изобретени  - упрощение технологического процесса путем обеспечени  ориентировани  абразивных зерен без их металлизации.The purpose of the invention is to simplify the process by providing orientation of the abrasive grains without their metallization.

На фиг 1 изображена схема установки; на фиг. 2 - схема, по сн юща  процесс ориентации абразивного зерна .Fig 1 shows the installation diagram; in fig. 2 is a schematic diagram explaining the process of orientation of the abrasive grain.

В разъемный корпус 1 помещена магнитна  система, вьшолненна  в виде сердечника 2 и нескольких сегментов 3, образующих кольцевой магнит вокруг сердечника. Магнитное поле возбу71у1. етг  посто нным током, пропускаемым через катушку 4. Полость между магнитной системой и корпусом заполнена ферромагнитной жидкостьюIn the detachable housing 1 is placed a magnetic system, implemented in the form of a core 2 and several segments 3, forming an annular magnet around the core. Magnetic field on the 71nd1. A constant current passing through the coil 4. The cavity between the magnetic system and the housing is filled with ferromagnetic liquid

5с включением абразивных зерен, предварительно покрытых пленкой кле , Корпус св зан с сердечником болтом5 with the inclusion of abrasive grains, pre-coated with adhesive film, the housing is connected with the core by a bolt

6и имеет возможность вместе с ним вращатьс . Сердечник приводитс  во вращение двигателем (не показан).6 and has the ability to rotate with it. The core is driven by a motor (not shown).

Сердечник подмагничен слабым током , пропускаемым через катушку А, поэтому сегменты 3 прит гиваютс  к нему и образуют кольцевой магнит. Полость корпуса заполн етс  ферромагнитной жидкостью 5 с включением абразивных зерен, покрытых пленкойThe core is magnetized by a weak current passing through the coil A, so the segments 3 are attracted to it and form a ring magnet. The cavity of the body is filled with ferromagnetic liquid 5 with the inclusion of abrasive grains coated with film
