Abstract
Изобретение относитс к производству абразивного инструмента, используемого дл обработки подшипниковых сталей. Целью изобретени вл етс сношение трудоемкости способа за счет сокращени продолжительности пропитки готовых абразивных инструментов . Абразивный круг на керамической св зке пропитывают водным раствором акриловой эмульсии, вл ющейс продуктом сополимеризации бутилового эфира акриловой кислоты, метилового эфира метакриловой кислоты, модифицированной полиэтиленгликолем, при следующем соотношении ингредиентов, мас.%: акрилова э ryльcи 6-30, вода - остальное. 2 табл.The invention relates to the manufacture of an abrasive tool used for machining bearing steels. The aim of the invention is to relate the complexity of the method by reducing the duration of the impregnation of the finished abrasive tools. An abrasive circle on a ceramic bond is impregnated with an aqueous solution of an acrylic emulsion that is a product of copolymerization of acrylic acid butyl ester, methacrylic acid methyl ester modified with polyethylene glycol, in the following ratio of ingredients, wt.%: Acrylic acid 6-30, water - the rest. 2 tab.
Description
Изобретение относитс к производству абразивного инструмента, используемого дл обработки подшип {иковых; сталей.The invention relates to the manufacture of an abrasive tool used for machining a bearing; steels.
Цель изобретени - снижение трудоемкости способа за счет сокращени продолжительности пропитки готовых абразивных инструментов.The purpose of the invention is to reduce the laboriousness of the method by reducing the duration of the impregnation of the finished abrasive tools.
Способ заключаетс в том, что го- товьй абразивньй инструмент на керамической св зке пропитьшают водньм раствором акриловой эмульсии, в- л ющейс продуктом сополимеризации б|утилового эфира акриловой кислоты (рутилакрилата), метилового эфира м:етакриловой кислоты (метилметакри- лата) и метакриловой кислоты, модифицированной полиэтиленгликолем, при соотношении компонентов от суммы мономеров 55,2:33,3:6,7:4,8% при следующем соотношении ингредиентов, м:ас.%:The method consists in that a ready-made abrasive tool on a ceramic bond is pierced with a water solution of an acrylic emulsion resulting from the copolymerization product of acrylic acid (rutile acrylate), methyl ester of m: ethacrylic acid (methyl methacrylate) and methacrylic acid polyethylene glycol modified acids, with a ratio of components to the sum of monomers 55.2: 33.3: 6.7: 4.8% with the following ratio of ingredients, m: ac.%:

Пропитку абразивного инструмента . осуществл ют погружением в пропиточный состав инструмента на 1-2 мин при комнатной температуре. Затем инструмент сушат при 110-120°С в те- .чение 5-6 ч.Impregnation of abrasive tools. carried out by immersion in the impregnating composition of the instrument for 1-2 minutes at room temperature. Then the instrument is dried at 110-120 ° C for 5-6 hours.
Шлифованию пропитанным инструментом подвергают борта внутреннего кольца подшипника 7609. В качестве СрЖ используют водный раствор кальцинированной соды (0,8-1,2%) с нитритом натри (0,2-0,9%), Режимы щли- ф)эванн : УК 35 м/с j Уде, м/мин , припуск 0,4 мм.

Круги пропитыва- ю|г пропиточными составами, представ- л нными в табл. 1.Grinding with the impregnated instrument is subjected to the bead of the inner ring of the bearing 7609. As the EFL, an aqueous solution of soda ash (0.8–1.2%) with sodium nitrite (0.2–0.9%) is used. 35 m / s j Ude, m / min, allowance 0.4 mm. One-to-one item processing time 19.0 s.

Основным преимуществом пред-лагае- мого способа в сравнении с известным вл етс снижение трудоемкости про- 1ШТКИ за счет одноэтапной пропитки круга готовым пропиточным составом при сохранении шероховатости обработанной поверхности и производительности обработки.The main advantage of the proposed method in comparison with the known method is a reduction in the labor intensity of 1STEMS due to one-step impregnation of the circle with a ready-made impregnating composition while maintaining the roughness of the treated surface and processing performance.
