Изобретение относитс  к материалам на медно основе, примен емым дл  изготовлени  снособом порошковой металлургии абразивных ннструментов, например, хонинговальных брусков, шлифовальных и доводочных кругов.This invention relates to copper-based materials used for the manufacture of abrasive tools, such as honing stones, grinding wheels and grinding wheels, by using powder metallurgy techniques.

Известен материал на медной основе, содержащий 4-20% олова и 1-3% фосфора.A known material is copper based, containing 4–20% tin and 1–3% phosphorus.

С целью повышени  антифрикционных свойств, исключени  засаливаемости ннструмента и обеспечени  его работы в режиме самозатачнвани  предложен материал на основе медн, который отличаетс  от известного тем, что фосфор введен в него в виде меднофосфористого сплава при следуюш,ем соотношении компонентов (в вес. %):In order to increase the antifriction properties, eliminate the salinization of the tool and ensure its operation in the self-shaking mode, a material based on copper has been proposed, which differs from the well-known fact that phosphorus is introduced into it as a copper-phosphorous alloy at the next component ratio (% by weight):

Предлагаемый материал получают смешиванием порошков меди, олова и меднофосфористого сплава с размером частиц менее 63 j-i в теченне двух часов, последующим перемешиванием полученной щихты с алмазным порошком и прессованием алмазоносной шихты под давлением 1,2 т/см.The proposed material is obtained by mixing powders of copper, tin, and a copper-phosphorous alloy with a particle size of less than 63 j-i for two hours, followed by stirring the resultant powder with diamond powder and pressing the diamond-bearing mixture under a pressure of 1.2 tons / cm.

Спекапие осуществл ют при температуре 620°С в теченне 30 минут, после чего прессформы с инструментом поступают на гор чую поднрессовку под давлением 1,2 т/см2.The speckapia is carried out at a temperature of 620 ° C for 30 minutes, after which the molds with the tool are fed to a hot sub press under a pressure of 1.2 tons / cm2.

Введеиие фосфора в виде меднофосфористого снлава новышает антнфрикцнонные свойства, в частностн, снижает коэффицие1гг трени  до з 1аченн  0,10 н существенно снижает температуру спекани  до 620°С, что в свою очередь предотвращает графитизацию алмазов.Introducing phosphorus in the form of a copper-phosphorous slate, which increases the anthalfric properties, in particular, reduces the coefficient of friction to 3 times a fraction of 0.10 n, significantly reduces the sintering temperature to 620 ° C, which in turn prevents the graphitization of diamonds.

Использование предложенного материала дл  изготовлени  абразивного инструмента позвол ет обеснечить прочное закреилепие абразивных частиц, самозатачивание инструмента , сннзить темнературу в зоне резани  и создает возможность обработки изделий с малыми усили ми резани .The use of the proposed material for the manufacture of an abrasive tool makes it possible to smooth out the strong hardness of the abrasive particles, to self-sharpen the tool, to reduce the temperature in the cutting zone and to create the possibility of processing products with low cutting forces.
