Today i was given a 20liter unopened drum of what the owner believed is cutting tool coolant. He says it's water soluable.
My problem is, (and out of interest sake), is since the drum labeling is mainly in Japanese characters with the only Engllish being the makers name (Noritaki), the letters CBN and SA-02. My research says Noritaki are a leading Japanese ceramics maker. CBN probably refers to cubic boron nitride. No idea what SA-02 means.
Bottom line, this stuff is more likely coolant for CBN grinding systems with those expensive grinding wheels that run at 12,000 rpm. Machines for making engine crankshafts etc.
Anyone recognise the codes and can i use it in normal lathe/milling hobby operations or am i sitting on a 20litre drum of waste?
