Metal cutting fluids, also known as cutting fluids or coolants, play a vital role in machining and metalworking processes by providing essential cooling, lubrication, and efficiency improvement. Commonly used in CNC machining, milling, and grinding machines, these cutting oils provide essential cooling and lubrication.

The primary functions of metal cutting fluids are to reduce heat generated during cutting to prevent tool overheating and workpiece distortion, reduce friction between the cutting tool and workpiece to extend tool life and improve surface finish, and inhibit corrosion of both the workpiece and cutting tool.

The difference between these types of cutting fluids lies in the amount of mineral oil and additives they contain, each tailored to specific machining needs. By offering a variety of cutting fluids, HLJH ensures optimal performance and protection for various machining applications, supporting both efficiency and sustainability in the metalworking industry.

Types of Metalworking Fluids: Water-Based and Neat Cutting Oils Water-Based Cutting Fluid

Water-based cutting fluids, commonly used in CNC machining, milling, and grinding, consist of surface-active additives and possess excellent cleaning properties. These fluids are designed to mix easily with water, forming stable emulsions that provide essential cooling and lubrication during metal cutting operations.

One of the primary challenges with water-based cutting fluids is their tendency to foam during machining. Foaming occurs due to entrained air from mechanical or chemical processes and the degree of agitation in the system.

Neat Cutting Oil

Neat cutting oils, or straight oils, are undiluted and used directly in various machining operations, ranging from light cuts to heavy-duty machine shop tasks. These oils are typically blends of mineral oils and other additives, providing excellent lubrication, enhancing tool life, and delivering a superior surface finish to the machined components. However, neat cutting oils tend to generate mist during machining, which can pose health risks to machine operators.
