Изобретение относитс  к смазочно-охлаждающим жидкост м (СОЖ), примен емым дл  механической обработки металлов, в частности при хонинговани, шлифовании и суперфинишировании.The invention relates to cutting fluids (coolant) used for the machining of metals, in particular during honing, grinding and superfinishing.

Известны СОЖ дл  шлифовани  на основе воды и ингибитора коррозии - нитрита натри . Однако при использовании известных СОЖ имеет место непосто нство съема металла , неравномерность скорости съема металла , брак на прижоги, брак на эллиптичность , засаливаиие брусков, что мешает автоматизации и программированию в технологии обработки металла.Coolant for water-based grinding and corrosion inhibitor sodium nitrite are known. However, when using known coolant systems, there is an inconvenience of metal removal, uneven metal removal rate, prizhogi defect, ellipticity failure, filling of bars, which interferes with automation and programming in metal processing technology.

Дл  повышени  качества обрабатываемой поверхности предложено в состав СОЖ вводить сахарозу и бисульфит натри  (СБ).To improve the quality of the treated surface, it has been proposed to introduce sucrose and sodium bisulfite (SB) into the coolant.

Состав СОЖ(СБ), вес. %:The composition of the coolant (SB), wt. %:

Сахароза0,5-1,0Saccharose 0.5-1.0

Бисульфит натри 0,05-0,1Sodium bisulfite 0.05-0.1

Нитрит натри 1,0-2,0Sodium nitrite 1.0-2.0

Способ приготовлени  новой СОЖ (СБ): компоненты СОЖ (СБ) раствор ют в водопроводной воде в любой последовательности или все вместе.The method of preparing a new coolant (SB): the components of the coolant (SB) is dissolved in tap water in any order or all together.

Разработанна  СОЖ (СБ) негорюча, пожаро- и взрывобезопасна, нетоксична, иеканцерогенна , безвредна, прозрачна, бесцйетиа (концентраци  активных компонентов составл ет пе более 3,1%), предотвращает брак на прожоги и на эллиптич юсть, не корродирует металл, долговечна в применении, не портитс , не засаливает бруски.The developed coolant (SB) is non-flammable, fire and explosion-proof, non-toxic, cancer-free, harmless, transparent, non-toxic (concentration of active components is more than 3.1%), prevents burns on the burn-through and on ellipticity, does not corrode metal, is durable application, does not spoil, does not salt bars.

Были проведены сравнительные испытани  СОЖ (СБ) на водной основе и керосина, смешанного с 10-20% веретенного масла. Испытани  проводились на круглошлифовалыюм станке модели ЗА110, приспособлепном дл  установки суперфинишной головки с регулируемой амплитудой 1-8 мм и частотой колебаний бруска 700, 1400, 2800 дв. х.лаш.Comparative tests of water-based coolant (LB) and kerosene mixed with 10-20% spun oil were carried out. The tests were carried out on a circular grinding machine model Z110, adaptable for installing a superfinishing head with an adjustable amplitude of 1-8 mm and a bar oscillation frequency of 700, 1400, 2800 dv. h.all

Обрабатываемые образцы - валики диаметром 60 мм, длииой 80 мм, материал - высоу опрочный магииевый чугун с шаровидным графитом (а 60 кг/льи, б 5,5%. твердость НВ 270-2&0) и серый чугун СЧ15-32 (твердость НВ 170-180). Образцы нредварительно отшлифовывают до чистоты поверхности У 6в и 7 7а.The samples to be processed are rollers with a diameter of 60 mm and a length of 80 mm, the material is high-grade spherical graphite cast iron (a 60 kg / li, b 5.5%. Hardness HB 270-2 & 0) and gray cast iron SC 15-32 (hardness HB 170-180). Samples are pre-polished to a surface cleanliness of U 6c and 7 7a.
