Mineral Cutting Oils
Water Soluble Coolants -WS50’s main function is to remove heat from the cutting tool, chip and work piece. The cutting oils are manufactured from highly refined Group 2 base oils that are low in Sulphur content. Group II base oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils.
Description
FEATURES
- Rust prevention to the component from cutting oils and water after machining
- Cutting efficiency 1.5 to 2 times compared to conventional oils
- Longer tank life 6-9 months without fouling owing to world class biocides
- Higher lubrication due to better quality oils
- Low concentration of blend 1:20 to 1:40 m Operational up to 700 ppm of hard water
- Fewest nicks and wear ability on tools
- Lower operational temperatures.
