Изобретение относитс к машиностроению и может быть использовано как чистова обработка.The invention relates to mechanical engineering and can be used as a finishing process.
Известны способы абразивной обработки поверхностей детали, при котором на обрабатываемую поверхность направл ют предварительно охлажденные частицы абразива 11 .Methods are known for the abrasive surface treatment of a part in which pre-cooled abrasive particles 11 are directed onto the surface to be treated.
Недостатком указанного способа вл етс его узкое назначение, работа при определенной температуре и ограниченный ассортимент примен емых веществ, одной, отдельно вз той технологической операцией, которой и ограничена область его применени .The disadvantage of this method is its narrow purpose, operation at a certain temperature and a limited range of used substances, one, separately taken technological operation, which limits its scope.
Цель изобретени - восстановление поверхностного рабочего сло частиц рабочего агента.The purpose of the invention is the restoration of the surface working layer of particles of the working agent.
Поставленна цель достигаетс тем, что обработку осуществл ют гидроабразивной средой, выбира температуру охлаждени частиц ниже температуры замерзани рабочей жидкости не менее чем на 5 С.The goal is achieved by processing with a hydroabrasive medium, choosing a particle cooling temperature below the freezing temperature of the working fluid by at least 5 ° C.
Частицы абразива, предварительно охлажденные до температур ниже температуры замерзани рабочей жидкости не менее чем на 5° С при попадаНИИ в поток обволакиваютс намерзающим слоем льда. Температурный интервал охлаждени частиц определ ет скорость намерзани и толщину сло , выбираетс в зависимости от . интенсивности режимов обработки, количества абразива в суспензии, необходимости замены абразива.The abrasive particles, pre-cooled to temperatures below the freezing point of the working fluid by at least 5 ° C, when the liquid enters the stream are enveloped by an freezing layer of ice. The temperature range for cooling the particles determines the freezing rate and the thickness of the layer, depending on depending on. intensity of processing modes, the amount of abrasive in suspension, the need to replace the abrasive.
При ударе частицы о поверхность детали слой льда, вл ющийс сам по Upon impact of a particle on the surface of a part, a layer of ice, which is itself
10 себе, вследствие кристаллического строени абразивом производит ударно-режущее воздействие на заготовку и преп тствует проникновению абразива в поры и складки поверхнос15 ти заготовки. После удара слой льда откалываетс , частица и продукта обработки оседают на дно. После некоторого перерыва, необходимого дл намораживани нового сло частица 10 itself, due to the crystalline structure of the abrasive, produces a shock-cutting effect on the workpiece and prevents the penetration of the abrasive into the pores and folds of the surface of the workpiece. After the impact, the ice layer breaks off, the particle and the product of the treatment settle to the bottom. After a break, required to freeze a new layer of particle
20 всплывает и цикл обработки возобновл етс . Нагревшиес частицы не всплывают и в обработке не участвуют. Это позвол ет варьировать э широком диапазоне режимы обработки, управ25 л ть количеством абразива в потоке, последовательно примен ть абразивы различной зернистости состава, веса, химсостава Поскольку обработка идет без контакта частиц абразива 30 с поверхностью заготовки резко уме20 floats and the processing cycle resumes. The heated particles do not float and do not participate in the processing. This allows you to vary the e wide range of processing modes, control the amount of abrasive in the stream, consistently apply abrasives of different grain sizes, composition, weight, chemical composition. Since the treatment goes without contact of the abrasive particles 30 with the surface of the workpiece, it is sharply
