Description

(54) СПОСОБ ИЗГОТОВЛЕНИЯ АЛМАЗНО-АБРАЗИВНОГО ИНСТРУМЕНТА С ОРИЕНТИРОВАННЫМ РАСПОЛОЖЕНИЕМ(54) METHOD OF MANUFACTURING A DIAMOND-ABRASIVE TOOL WITH AN ORIENTED LOCATION

1one

Изобретение относитс  к инстру1ментальному производству, в частности к способам изготовлени  алмазно-абразивного шлифовального инструмента, и может быть использовано при изготовлении шлифовальных кругов, брусков, сегментов, имеющих 5 ориентированные абразивные зерна.The invention relates to the instrumental production, in particular, to methods for manufacturing a diamond-abrasive grinding tool, and can be used in the manufacture of grinding wheels, bars, segments having 5 oriented abrasive grains.

Известен способ изготовлени  абразивно-алмазного инструмента с ориентированными абразивными зернами, согласно которому в абразивную массу ввод т металли- JQ зированные абразивные зерна, производ т ориентацию последних в магнитном поле, прессуют и термически обрабатывают 1.A known method of making abrasive-diamond tools with oriented abrasive grains, according to which metal-JQ zoned abrasive grains are introduced into the abrasive mass, the latter are oriented in a magnetic field, pressed and thermally processed 1.

Однако игзвестный способ характеризуетс  недостаточной стойкостью инструмента, а также его прочностью в заданном нап- 15 равлении.However, the well-known method is characterized by insufficient tool durability, as well as its strength in a given direction.

Цель изобретени  - повышение эксплуатационных возможностей инструмента с ориентированными зернами за счет повышени  его стойкости и прочности в задан- ,0 ном направлении.The purpose of the invention is to increase the operational capabilities of the tool with oriented grains by increasing its durability and strength in a given direction.

Поставленна  цель достигаетс  тем, что согласно способу в св зующую массу, содержащую металлизированные магнитным материаЛом зерна, перед магнитной ориентаЗЕРЕНThe goal is achieved by the fact that according to the method, in the binding mass containing the grains metallized with magnetic material, before the magnetic orientation is

цией, дополнительно ввод т мелкозернистый феррит с продолговатой формой зерна, зернистостью на 2-4 номера меньше зернистости абразива.In addition, fine-grained ferrite with an elongated grain shape is additionally introduced, the grit is 2-4 numbers less than the abrasive grit.

Зерна феррита при помещении их в магнитное поле разворачиваютс , строго ориентиру сь вдоль магнитных силовых линий, идентично абразивным зернам.When placed in a magnetic field, ferrite grains unfold, strictly oriented along magnetic field lines, identical to abrasive grains.

Таким образом, инструмент снабжен дополнительными ориентированными режущими зернами (ферритом), которые, име  высокую микротвердость, активно участвуют в обработке, повыша  тем самым стойкость и прочность инструмента в заданном направлении.Thus, the tool is equipped with additional oriented cutting grains (ferrite), which, having a high microhardness, are actively involved in the processing, thereby increasing tool durability and strength in a given direction.

Зерна феррита должны быть меньше металлизированных абразивных зерен (например на 2-4 номера по ГОСТ 9206-70).Ferrite grains should be less than metallized abrasive grains (for example, 2-4 numbers according to GOST 9206-70).

Пример. Изготавливаетс  шлифовальный круг АЧК с ориентированным расположением алмазных зерен с введением мелкозернистого феррита, классифицированного по размеру и форме до 50% от объема абразивной смеси. При этом используетс , например, св зка Б1, алмазный порошок АСП металлизированный никелем, 100% кон- центраци . Подготовленна  навеска засыпаетс  в рабочую полость пресс-формы, включаетс  ориентирующее магнитное поле и осуществл етс  прессование с термической обработкой по известной технологии.Example. The grinding wheel of the AChK is made with an oriented arrangement of diamond grains with the introduction of fine-grained ferrite, classified by size and shape up to 50% of the volume of the abrasive mixture. This uses, for example, B1 bond, diamond powder AST metallized with nickel, 100% concentration. The prepared sample is poured into the working cavity of the mold, the orienting magnetic field is turned on, and pressing is carried out with heat treatment according to a known technology.

Производительность обработки по предлагаемому способу повышаетс  на 10- 15%, износостойкость инструмента увеличиваетс  на 20-40%.The processing capacity of the proposed method is increased by 10-15%, the wear resistance of the tool is increased by 20-40%.
