Metal cutting fluids, also known as cutting fluids or coolants, play a vital role in machining and metalworking processes. These fluids are essential for cooling, lubricating, and improving the efficiency of metal cutting operations.

Today, modern cutting fluids (cutting oils) are subjected to a variety of demands which play a crucial role in the metalworking industry that must be effective, economical, and free from ingredients that are harmful to health and the environment.


As a manufacturer and supplier of cutting fluids, Hai Lu Jya He (HLJH), we offer a complete range of metalworking fluids - soluble cutting oils, semi-synthetic cutting oils, synthetic cutting fluids, neat cutting oils. The difference between the above types is about the amount of mineral oil and additives in it. The primary functions of metal cutting fluids are to: a. Cooling: Reduce heat generated during cutting to prevent tool overheating and workpiece distortion. b. Lubrication: Reduce friction between the cutting tool and workpiece, extending tool life and improving surface finish. c. Corrosion Protection: Inhibit corrosion of both the workpiece and cutting tool. Here are types of metal cutting fluids:


Neat Cutting Oil

Neat cutting oils are used in a variety of machining operations - from light cuts to heavy-duty machine shop operations. They are generally blends of mineral oils and other additives and used for cutting without further dilution.Neat cutting oil (straight oil) provides excellent lubrication, leads to good tool life and appropriate surface finish of the components. BUT, neat cutting oil is easy to get mist during machining. As we know, machine shop mist can affect the health of machine operators. Mist settles out on the surrounding environment creating an unhealthy working area. That’s why more people use water-based cutting fluid instead of neat cutting oil these years.


Water-based Cutting Fluid

Regarding water-based cutting fluids, it consists of surface-active additives and good cleaning properties. However, they may tend to foam up a bit during machining. Foaming occurs in your CNC's coolant because of entrained air by mechanical or chemical processes, and the degree of agitation in the system. You can get rid of foam in a coolant tank "temporarily" by adding defoamers. Or ask for water-based cutting oil which has good anti-foamimg ability by the cutting oil provider.


Each one of the cutting oils has its own advantages. But, what is suitable for you? It depends on the machining process (light-duty to heavy-duty cutting) and metal materials (ferrous or non-ferrous).Hai Lu Jya He (HLJH) mainly offers MORESCO and WILL two brands of metalworking fluids which have high and stable quality for customers. They advocate producing without chlorine additives that decrease the environmental impacts.
