Oil ILS-10 (TU 38.1011191-97) — distilling oil from sulphurous petroleums of deep selective clearing with antioxidizing, antiwear, anticorrosive and antifoamy additives. Are intended for high-speed spindle unit of metal-cutting machine tools.
Oil ИЛС-10 economically is the most expedient for using instead of oils corresponding on viscosity without additives I-5A and I-8A.
Viscosity kinematic, cSt, at 40°С, not less: 9-11
Mass fraction of zinc, %, not less: 0.04
Mass fraction of sulphur, %, not less: 0.9
Flash temperature, in opened crucible, °C, not more low: 143
Hardening temperature, °C, not above: -15
Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can influence work of components.
