Semi-synthetic Cutting Oils

As a manufacturer and supplier of metalworking fluids, we offer the premium semi-synthetic cutting oils for machining of ferrous and non – ferrous metal and alloys that form a translucent emulsion when mixed water.


Semi-synthetic oils contain 30% to 50% mineral oil, and have extreme pressure additives and frictional modifiers that offer extended tool life, improved surface finishing, heat dissipation and better emulsion service life. It resists bacterial attack to control the emulsion stability with excellent rust and corrosion protections.

Water-based cutting fluids have surface-active additives and good cleaning properties. However, they may tend to foam up a bit during machining. BUT, semi-synthetic cutting oil is always best seller which has low foaming and dissipating heat faster falls between the soluble cutting oil and synthetic fluids. Some people use the semi-synthetic ones due to their ability to combine the benefits of both soluble cutting oil and synthetic cutting fluids.


For good lubrication and tool life, most heavy duty soluble cutting oils have added chlorine to enhance extreme pressure machining. However, MORESCO series and WILL AIE series emphasized products without chlorine additives that are not harmful for human health.
Reminder, when you are facing the foaming issue, you can get rid of foam in a coolant tank "temporarily" by adding a defoamer. Or ask for water-based cutting oil which has good anti-foamimg ability by the cutting oil provider.
