Изобретение относитс  к составам дл  виброхимического сн ти  заусенцев и может быть использовано в приборостроении и часовой промышленности .The invention relates to compositions for vibrochemical deburring and can be used in instrument engineering and the watch industry.

Целью изобретени   вл етс  повьше ние качества обработки.The aim of the invention is to increase the quality of processing.

Пример. Дл  обработки берут детали из меди Ml с площадью поверхности 4,8 см и толщиной 100-120 мкм Обработку провод т в контейнере объемом 150 мл, заполненном на 2/3 объема смесью деталей и абразива ПТ-5, объем заливаемого в контейнер рабочего раствора 50 мл, количество деталей 20 шт (соотношение объема обрабатывающего раствора и количества деталей берут оптимальным). Температура раствора 20°С (рекомендуема  температура 15-30°С), частота колебаний вибратора 3000 мин .Example. For processing, parts of copper Ml with a surface area of 4.8 cm and a thickness of 100-120 µm are taken. The treatment is carried out in a 150 ml container filled to 2/3 volume with a mixture of parts and abrasive PT-5, the volume of the working solution 50 poured into the container ml, the number of parts 20 pieces (the ratio of the volume of the processing solution and the number of parts take the best). The temperature of the solution is 20 ° C (recommended temperature is 15-30 ° C), the oscillation frequency of the vibrator is 3000 minutes.

Результаты обработки представлены в таблице.The results of processing are presented in the table.

В таблице указана избирательность процесса. Под этой величиной понимаетс  разность между толщиной удален- ного заусенца и изменением толщины детали, отнесенна  к толщине удаленного заусенца и вз та  в процентах.The table indicates the selectivity of the process. By this value is meant the difference between the thickness of the removed burr and the change in the thickness of the part, referred to the thickness of the removed burr and taken as a percentage.

Пленку, образующуюс  на детал х в процессе обработки, удал ют в растворе азотной кислоты, разбавленной 1:1, на виброустановке или простым погружением в емкость с кислотой на 1-2 мин.The film formed on the parts during processing is removed in a solution of nitric acid, diluted 1: 1, on a vibration unit or simply immersed in a container with acid for 1-2 minutes.

пределах: 0,01-0,08 г/см . Если брать это отношение меньше, чем 0,01 г/см, то заусенцы снимаютс  неполностью. Увеличивать данное от ношение больше 0,08 г/см нецелесообразно , так как увеличение концент рации дорогосто щего компонента не приводит ни к выигрьш1у по времени обработки, ни к выигрьшгу по избирательности .limits: 0.01-0.08 g / cm. If this ratio is less than 0.01 g / cm, the burrs are not completely removed. It is impractical to increase this ratio by more than 0.08 g / cm, since an increase in the concentration of the expensive component does not lead to a gain in processing time or a gain in selectivity.

Как видно из таблицы, при меньших концентраци х компонентов увеличиваетс  врем  обработки, но возрастает избирательность процесса. При максимальных концентраци х компонентов избирательность несколько падает, но при зтом существенно сокращаетс  врем  обработки.As can be seen from the table, at lower concentrations of components, the processing time increases, but the selectivity of the process increases. At maximum concentrations of the components, the selectivity decreases slightly, but at this time, the processing time is significantly reduced.

Предлагаемый раствор позвол ет эффективно и с высокой избиратель- ностью (80-90%) снимать с деталей из меди заусенцы толщиной 100-120 мкм.The proposed solution allows effectively and with high selectivity (80-90%) to remove burrs with a thickness of 100-120 microns from copper parts.
