BC-105 is a water-soluble, bio-stable semi-synthetic cutting fluid. Mixed with water it forms a clear solution with good cleaning and lubrication performance, and it handles most common cutting and grinding operations in the electronics and automotive industries.
It avoids the usual problems of machining centres: pH that drifts out of control, unstable emulsion, hydrogen generation and fluid that turns.
Performance
- Good surface finish, and longer tool life even in difficult cuts
- Good lubrication with low foam
- Works across mixed metals, which keeps cost down
- Good wetting, so less fluid is carried out on the part and swarf, and tools and workpieces stay clean
- Very long sump life, which limits loss to odour and spoilage
- Balanced overall performance, so there is less downtime for cleaning, filtration and fluid changes
Applications
Suited to high-volume production on forged steel, ductile and grey cast iron and most ferrous alloys and non-ferrous metals. It performs particularly well in difficult operations such as reaming and tapping hard metals.
How to use
- For general grinding, add 5 percent by weight to tap water to form a uniform clear fluid
- Top up with fresh fluid after removing swarf; keeping the concentration above 5 percent gives long fluid life
Notes
- Mix to the stated ratio, otherwise lubrication and corrosion protection drop
- Keep the fluid clean and do not mix it with other oils
- After shutting down, wipe the fluid off the machine with a dry cloth and oil the surfaces
- For workpieces in poorer materials that will be stored for a long time, apply corrosion protection
