Изобретение относитс  к обработке мате- )иалов резанием, а именно к способам по- Дачи смазочно-охлаждающей жидкости (СОЖ) в зону резани  при обработке кольцевым алмазным инструментом. The invention relates to the processing of materials by cutting, in particular to methods for supplying coolant (coolant) to the cutting zone when machining with a ring diamond tool.

Целью изобретени   вл етс  повышение Надежности подачи СОЖ за счет ликвидации утечек через шпиндель.The aim of the invention is to increase the reliability of coolant supply due to the elimination of spindle leaks.

На чертеже приведена схема устройства дл  осуш.ествлени  способа.The drawing shows a diagram of the device for drying the method.

Способ осуществл ют следующим обра- еом.The method is carried out as follows.

: СОЖ ПО трубопроводу 1 подают в по- jiocTb 2 шпиндел  3, закрепленного в кор- fiyce 4 на опорах 5. Трубопровод 1 введен Ь полость 2 на глубину 3-5 диаметров тру- опровода 1 с зазором 6 между стенками по- IIOCTH 2 и внешней поверхностью трубопро- ода 1. Шпиндель 3 закреплен на корпусе 4 t зазором 7. В корпусе 4 расположен канал дл  подачи воздуха в полость 9 между кор- fiycoM 4, трубопроводом и торцом шпинде- |1  3. Воздух подают под давлением Р, которое выбирают из услови  Pj Ре - (2...3)Р (де РЗ давление СОЖ в зазоре 6, а Р, - |1авление СОЖ в трубопроводе. Это дав- |1ение предотвращает утечку СОЖ через Цзор 6 и полость 9 и зазор 7. СОЖ протекает по полости 2 в зону резани  10 по |;тенкам полости 2 и попадает на инструмент И и деталь 12, интенсивно вымыва  оттуда и охлажда  инструмент П. Воздух Ь полости 2 прижимает СОЖ к ее стенкам.: Coolant software for pipeline 1 is fed to jiocTb 2 spindle 3 fixed in box-fiyce 4 on supports 5. Pipeline 1 is inserted into cavity 2 to a depth of 3-5 diameters of pipe 1 with a gap 6 between the walls of IIOCTH 2 and the outer surface of the pipeline 1. The spindle 3 is fixed on the casing 4 t by a gap 7. In the casing 4 there is a channel for supplying air to the cavity 9 between the fiycoM 4, the pipeline and the spindle end- | 1 3. Air is supplied under pressure P, which choose from the condition Pj Re - (2 ... 3) P (de RZ is the pressure of the coolant in the gap 6, and P, is the pressure of the coolant in the pipeline. This pressure prevents coolant leak through Zsor 6 and cavity 9 and gap 7. Coolant flows through cavity 2 into cutting zone 10 in |; cavity 2 and gets into tool AND and part 12, intensively washing out and cooling tool P. Air of cavity 2 presses coolant to its walls.
