Metal removal processes, such as machining and grinding, are integral to manufacturing industries worldwide. Performed using precision-certified Computer Numerical Control (CNC) machines and cutting tools, these processes shape metal components with precision. However, to maintain efficiency, prolong tool life, and ensure a high-quality surface finish on the final product, the use of cutting fluids is essential.
Cutting fluids serve multiple functions during metal removal operations, ranging from lubrication to cooling and rust prevention. Manufacturers typically choose between straight undiluted cutting oil and water-soluble cutting fluid, each offering specific advantages depending on the material and the task at hand. Understanding how cutting fluids work and selecting the right one for your operation can significantly improve tool performance and workpiece quality.
- Lubricate – A cutting fluid reduces the friction encountered when a cutting tool is used to cut a metal workpiece. By reducing friction, tool life is maximized, extending the tool’s ‘good’ economic working life. This lubrication also minimizes the energy required to cut through metal, enhancing the overall efficiency of the operation. It helps produce a smooth surface finish on the machined parts, which is crucial in high-precision manufacturing environments.   Â
- Cool – The temperatures at the tool-workpiece interface can reach to 700°C during contact. A cutting fluid absorbs this heat, preventing the formation of built-up edges—a phenomenon where metal chips are welded into the cutting tool. A tool with a built-up edge can lead to dimensional inaccuracies and defective workpieces. Cooling helps reduce thermal fatigue in the tool, which can significantly prolong its lifespan. Water soluble cutting fluid is effective at cooling, making it a popular choice among many metalworking fluids manufacturers.
- Prevent Rust and Corrosion – Ferrous metals, such as steel, are highly susceptible to rust when exposed to oxygen and moisture. A quality cutting fluid provides short-term rust protection, safeguarding both the workpiece and the tool. Cutting fluids need to contain additives to prevent staining or corrosion for non-ferrous metals like aluminum, copper, and zinc. Rust prevention and corrosion prevention are critical for maintaining the integrity of both the machine and the product, making this an essential feature in water-soluble coolant metal-cutting fluids.
- Wash Away Chips – The recirculation of metal debris can negatively impact tool life and surface finish. Cutting fluids act as flushing agents, removing metal chips from the machining or grinding area. This is vital, as the recirculation of metal debris can negatively impact tool life and surface finish. Effective chip removal ensures that the final product meets the high standards required in modern manufacturing processes.
Selecting the Right Cutting Fluid for Your Operation

In the competitive manufacturing industry, choosing the right cutting fluid is crucial for achieving optimal performance and cost efficiency. Whether you’re working with ferrous or non-ferrous metals, high-speed CNC machining, or precision grinding, the selection of a metal cutting fluid that provides effective lubrication, cooling, rust prevention, and chip removal is key to your operation’s success.
The technologies range from straight oils to water-soluble cutting fluids, each offering unique benefits. Straight oils, offer excellent lubrication and are ideal for low-speed operations, while water-soluble coolants are favored for their superior cooling and chip-removal properties in high-speed environments.
