Abstract

1440401 Abrasive tools VSESOJUZ NI I PROEKT INST TUGOPLAVKIKH METALLOV I TVERDYKH SPLAVOV 3 Jan 1974 [3 Jan 1973] 00317/74 Heading B3D [Also in Division E1] A rock drill bit 1 has a working head 2 including fine abrasive grains 4 occupying an intermediate metallic layer 3 and coarse abrasive grains 7 occupying the intermediate layer and an outer metallic layer 5 free of fine abrasive grains, the inner metallic layer 8 also being free of fine abrasive grins. Each of the coarse grains has ¢-<SP>2</SP>/ 3 of its volume disposed in the intermediate layer and the remainder in the outer layer. Suggested compositions for the layers 3, 5, 8 include (a) nickel, iron and tungsten carbide and (b) tungsten-carbide and cobalt, and it is stated that in making the working head in a graphite mould the layers are impregnated with melts of copper, copper and nickel, copper with nickel and zinc or copper, silver and zinc after they have been pressed. The coarse abrasive grains may be of, e.g. natural or synthetic diamond or cubic boron nitride and are 1-2À5 mm. in size and the fine abrasive grains may be of like materials to the coarse grains or of tungsten carbide and are 50-800 microns in size. Layers 3, 5 normally have a combined thickness equal to the size of the coarse grains.

Всесоюзный научно-исследовательский и проектный институт тугоплавких металлов и твердых сплавов (5ί) СПОСОБ ИЗГОТОВЛЕНИЯ АЛМАЗНОГО БУРОВОГО ? ИНСТРУМЕНТАAll-Union Research and Design Institute of Refractory Metals and Hard Alloys (5ί) METHOD FOR PRODUCING DIAMOND DRILLING? TOOLS

ί)ί)

Известен способ изготовления алмазного бурового инструмента, заключающийся в засыпке шихты в прессформу, укладке основных алмазов и j пропитке;A known method of manufacturing a diamond drilling tool, which consists in filling the charge into the mold, laying the main diamonds and j impregnation;

Цель изобретения — повышение стойкости инструмента.The purpose of the invention is to increase the tool life.

Для этого в предлагаемом способе основные алмазы засыпают на 1/2-2/3 jg их высоты шихтой, импрегнированной более мелкими по сравнению с основными алмазами, а затем производят досыпку обычной шихты.To do this, in the proposed method, the main diamonds are poured at 1 / 2-2 / 3 jg of their height with a charge impregnated with smaller ones compared to the main diamonds, and then the usual charge is refilled.

Способ заключается в следующем. ._The method is as follows. ._

В пресс-форму укладывают основные 5 режущие алмазные зерна. Засыпают на 1/2-2/3 высоты основных алмазных зерен обычную шихту, например, на основе карбида вольфрама. На обычную __ шихту на величину 2/3-1/2 высоты основных алмазных зерен насыпают шихту, ймпрегнированную мелкими алмазами. Производят досыпку до требуемого объема обычной шихтой. Устанавливают в пресс-форму корпус инструмента, прессуют и осуществляют пропитку металлом или сплавом.The main 5 cutting diamond grains are placed in the mold. An ordinary charge, for example, based on tungsten carbide, is poured at 1 / 2-2 / 3 of the height of the main diamond grains. On a regular __ charge, the charge, impregnated with small diamonds, is poured to a value of 2 / 3-1 / 2 of the height of the main diamond grains. Fill up to the required volume with a conventional charge. The tool body is installed in the mold, pressed and impregnated with metal or alloy.
