Applications include precision tool grinding, surface grinding, cylindrical grinding, fine profile grinding and lapping. Materials include steel; hardening and tempering steels; high speed steel; hard alloy; stainless steel; and carbide.
The oil is said to have excellent wetting and rinsing behavior, which improves surface quality and grinding wheel life. Compared to mineral oils, it has a high flash point and reduced emissions, the company says. The oil is suitable for grinding of tungsten carbide without cobalt leaching.
