Phenolic Soluble Oil Based on Solvent Refined Mineral Oil
SUPEREDGE® 7 is a phenolic soluble oil based on solvent refined mineral oil containing
sulphurised and chlorinated EP additives. Forms an opaque milky brown emulsion.
Specially designed for severe operations on difficult to machine materials where more
expensive neat cutting oils were regarded as essential. e.g. general machining, multi-tool
and auto lathe work, deep hole drilling, tapping, gear roughing, broaching and high speed
grinding on both ferrous and non-ferrous materials, including difficult to machine
materials. Also recommended for general purpose light to medium duty pressing,
stamping, wire and tube drawing operations on ferrous metals.
Benefits and Qualities
Long service life,
Anti-bacterial and anti-rust properties.
EP additives prevent loading of grinding wheels with metal pick up when grinding
“stringy” metals such as stainless steel and other alloys.
Mild and Low
Deep hole drilling
Measuring Emulsion Strength
To ensure optimum performance of the emulsion, check the emulsion strength weekly,
and adjust if necessary.
A quick, easy and accurate method is by using a refractometer, such as the Atago N10
Hand Sugar Refractometer, available from Castrol. The following graph converts the
refractometer readings to percentage concentration for SUPEREDGE® 7.
Method of Use
Zero instrument according to manufacturer’s instructions, including
allowance for temperature variations.
