Изобретение относитс к изготовлению абразивного инструмента.The invention relates to the manufacture of an abrasive tool.
Известны способы повышени износосто1ж0сти абравивного инструмента, заключающиес в термичеокой обработ1ке ииструмента ;в восстановительной , например водо-роднай, среде.Methods are known for increasing the wear and tear of an abrasive tool, consisting of a heat treatment and a tool, and in a reducing, for example, hydrogen, medium.
Дл повышени износостойкости абразивного инструмента на органической св зке предлагаетс абразивный инструмент подвергать дополнительной термической обработке со скоростью 45 град/час с последующим повышением до 280°С.To increase the wear resistance of an organic-bonded abrasive tool, an abrasive tool is proposed to be subjected to additional heat treatment at a rate of 45 degrees / hour, followed by an increase to 280 ° C.
Термическую обработку ведут в два этапа. Вначале ииструмент нагревают до 120°С со скоростью 45 град/час. Затем температуру оовышают до 280°С со скоростью не более 35 град/час, выдерживают при этой температуре в течение 30 мин и охлаждают до 40°С со скоростью не более 70 epadj4ac.Heat treatment is carried out in two stages. Initially, the instrument is heated to 120 ° C at a rate of 45 deg / h. Then the temperature is increased to 280 ° C at a speed of not more than 35 degrees / hour, kept at this temperature for 30 minutes and cooled to 40 ° C at a speed of not more than 70 epadj4ac.
Предмет изобретени Subject invention
Способ повышени износостойкости абразивного инструмента, заключающийс в термической обработке его в восстановительной, например водородной, среде, отличающийс тем, что, с целью уменьшени удельного расхода абразива в инструментах на оргаиичеокой св зке, последние подвергают дополнительной термообработке при нагреве до 120°С со скоростью не более 45 град/час с последующим повышением температуры до 280°С со скоростью не более 35 град/час, выдержкой при этой температуре в течение 30 мин и охлаждением до 40°С со скоростью не более 70 град/час.A method of increasing the wear resistance of an abrasive tool, consisting in heat treating it in a reducing, e.g. more than 45 degrees / hour with subsequent temperature rise up to 280 ° C at a speed of not more than 35 degrees / hour, holding at this temperature for 30 minutes and cooling to 40 ° C at a speed of not more than 70 degrees / hour .
