Изобретение .касаетс  изготовлени  изделий из дисперсных сплавов, в ча-стности алмазио-абразивного инструмента на металлической Св зке.The invention relates to the manufacture of products from dispersed alloys, in particular, diamond-abrasive tools on a metal link.

Известен способ повышени  1соде|ржани  диоперснЫХ частиц в рабочем слое алмазноабразиганого и«стру1мента пр(и изтотовлении и. из литых диоперОных оплавов, заключающийс  в фильтрации И3(быточ1ного количества жидкой составл ющей дисперсного опла1ва под давлением. При этом концентраци  абразивных частиц составл ет об. %.There is a known method for increasing 1SOD | rye of dioperc particles in the working layer of diamond-coated and пр pr structures (and making them from cast dioper oplums, which consists in filtering I3 (the total amount of the liquid component of the dispersed heat under pressure. %

Однако при высокопроизводительных обдирочных операци х при зачистке отливок, слитков и так далее концентраци  абразивных частиц должна -саставл ть 70-80 об. %. Изготовление таких высокопористых изделий с ,минотмалвны1М содержанием св зующего известным способом левоз1мож)но.However, during high-performance grinding operations when stripping castings, ingots, and so on, the concentration of abrasive particles should be 70-80 vol. % The fabrication of such highly porous products with the minotmal 1M content of the binder known in a known manner can be used.

Целью изобретени   вл етс  обеспечение оптимального сочетани  режущих и стойкост ых свойств инструмента.The aim of the invention is to provide an optimal combination of cutting and resistance properties of the tool.

Дл  ЭТО1ГО фильтрацию избыточного количества жидкого металла произ1вод т под действием упругих колебаний. При этом содержапие дисперсных частиц (повышаетс  до 70-80 об. %.For IT, an excess amount of liquid metal is filtered under the action of elastic vibrations. At the same time, the content of dispersed particles (increases to 70-80% by volume.

Фор.му, предназначенную дл  изготовлени  алмазно-абразивного инструмента, заполненую pacплaiвлeнны м дисперсныл сплавом, подвергают действию упругих кчолебаиий, например , помеща  ее на вибростол. Частота колебаний составл ет 50-1000 гц. Величина зазоров в фор1ме :вьгбираетс  из услови , чтобы фильтровалась только жидка  фаза. После фильтрации жидкой фазы и получени  требуемой формы и раз1меров издели  действие упругих колебаний прекращают, форму охлаждают и извлекают из нее пористое изделие . Еще одии.м преимуществом способа  вл етс  отсутствие слолчиого прессового оборудовани , сложных и дорогосто щих прессформ .A mold intended for the manufacture of a diamond-abrasive tool, filled with dissipated alloy, is subjected to the action of elastic cholebals, for example, by placing it on a vibrating table. The oscillation frequency is 50-1000 Hz. The size of the gaps in the form: is chosen from the condition that only the liquid phase is filtered. After filtering the liquid phase and obtaining the desired shape and dimensions of the product, the action of the elastic oscillations is stopped, the shape is cooled and the porous product is removed from it. Another advantage of this method is the absence of laminating press equipment, complex and expensive molds.
