Basic Coolant Categories
What You Need To Know: Semi-Synthetics & Micro Emulsions: Have less than 30% mineral oil content in concentrate & the concentrate contains water. Dilution appears translucent. One of the benefits is short term rust protection as the coolant leaves an oily film on parts. Products reject tramp oils effectively, and the emulsions are very stable and long-lasting. Better cooling allows higher cutting speeds and they combine the best features of synthetics and soluble oils. Semi-synthetic emulsions provide micro-sized oil droplets, beneficial in single-point turning applications that require optimal cooling with less lubrication. Read more…
Practical Information on Synthetic Coolants
Synthetic Coolants are a class of metalworking coolants that do NOT contain oil. Formulations include additives to provide lubricity, prevent rusting, control foam, and control or prevent microbial growth.
