Изобретение относитс к производству абразивного инструмента.This invention relates to the manufacture of an abrasive tool.
По основному авт. св. № 366963 известен сиособ иовышени экснлуатационных свойств абразивного инструмента. Известный сиособ предусматривает проиитку абразивного инструмента в специальной среде, обеспечивающей воздействие на инструмент низкой температуры . При этом в качестве специальной среды используют сжиженные газы, например , азот, гелий.According to the main author. St. No. 366963 is well known for its improved use of abrasive tools. The well-known siosob provides for the development of abrasive tools in a special environment, providing the impact on the tool low temperature. At the same time, liquefied gases, for example, nitrogen, helium, are used as a special medium.
С целью дальнейшего иовышени стойкости инструмента предложена специальна термическа обработка, заключающа с в том, что абразивный инструмент устанавливают в нагревательное устройство, подогревают до определенной темиературы, наиример 200°С, выдерживают там определенное врем в зависимости от характеристики инструмента, например 10-15 мин, затем вынимают и сразу опускают в холодную среду: воду, жидкий азот и т. п., после чего вынимают и высушивают .For the purpose of further increasing the tool life, a special thermal treatment was proposed, namely, that the abrasive tool was installed in a heating device, heated to a certain temperature, preferably 200 ° C, held there for a certain time depending on the characteristics of the tool, for example 10-15 minutes, then removed and immediately immersed in a cold environment: water, liquid nitrogen, etc., and then removed and dried.
Предусмотрено указанную последовательность операций проводить однократно или многократно при разных температурах и различных средах.The specified sequence of operations is carried out once or repeatedly at different temperatures and different environments.
Лимитирующим фактором вл етс критический перепад температур, выше которого может произойти разрыв круга. Определено, что этот перепад должен лежать в диапазоне 200-300°С.The limiting factor is the critical temperature difference, above which a circle may occur. It is determined that this difference should lie in the range of 200-300 ° C.
