Application
Additive package for the formulation of grinding oils for the machining of cemented carbides and high-speed
steel. Also suitable for other cutting processes with geometrically not defined cutting edges (honing, lapping,
superfinishing) and for light duty cutting processes with geometrically defined cutting edges (precision turning,
finish-milling).
Additin RC 9701 is an ashless additive package which provides EP properties as well as excellent antiwear- and
flushing properties. The grinding wheels remain free. The additive package has nearly no negative effect on the
foaming and air release properties of the baseoil. When machining cemented carbides the leaching of cobalt
from the workpiece material is minimized.
The recommended treat rate for the formulation of grinding oils for cemented carbides and high-speed steel is
1 %wt in base oils with viscosity adjusted to the requirements of the metalworking process.
