Used for preparation of (3-6)% water emulsions during processing of alloyed structural steels at medium cutting modes, as well as at grinding of carbon and alloyed steels. Emulsol can be also used for turning, milling and drilling. 5% water emulsion of emulsol can be applied to all operations of edging and abrasive processing of aluminum, cast-iron and bronze. Emulsol is a mixture of petroleum oils and corrosion inhibitors. Emulsol EM-1 is an analogue of emulsols ET-2U, EGT, ET-2. It has high washing, penetrating and cooling capacity, provides higher tool durability and lower roughness of processed surfaces. EM-1 does not form any toxic compounds with other substances in the air or sewage waters.
