CNC cutting fluid is a cooling lubricant used in metal cutting and machining processes in industrial machining. It is widely used in CNC machining and has the following benefits:

Cooling: The cutting fluid can quickly take away the heat generated during the cutting process, effectively reduce the temperature of the workpiece and the cutting tool, and prevent thermal deformation and rapid wear of the cutting tool during processing.

Lubrication: Cutting fluid can reduce cutting friction, reduce cutting force and improve the quality of machined surface. It can form a lubricating film during processing, which can lubricate and reduce wear between the tool and the workpiece. At the same time, the cutting fluid can prevent the outflow of lubricant and other external pollutants from entering the friction surface to a certain extent, avoiding the aggravation of friction.

Anti-rust: The anti-rust agent in the cutting fluid can prevent the metal workpiece from rusting due to direct contact with friction and moisture during the cutting process, and protect the smoothness and precision of the surface of the workpiece.

Cleaning: Cutting fluid can also clean the processing area, remove chips and dirt during cutting, and keep workpieces and equipment clean.

Noise reduction: During the cutting process, cutting fluid can reduce cutting noise and vibration, providing a relatively quiet working environment. Relatively speaking, it can protect the physical and mental health of the operator to a certain extent, improve work efficiency and reduce the accident rate.

According to its composition and use, cutting fluid can be divided into various classifications. The following are common cutting fluid classifications:

Water-soluble cutting fluid: The main component is water, which can dilute and cool the cutting area during processing, and is widely used in most castings, machining and other fields.

Drilling oil: mainly composed of lubricating and anti-rust agents, suitable for occasions requiring high precision such as high-speed drilling and thread processing.

Cutting oil: mainly composed of lubricants, suitable for heavy-duty cutting, turning, milling and other processes, especially in the field of steel processing.

Cutting wax: mainly composed of wax and lubricant, suitable for low-load and low-speed cutting processes, such as copper and aluminum processing.

Thin oil: usually made of mineral oil or synthetic oil, suitable for machining non-metallic (such as plastic) or difficult-to-cut materials.

The above are just the common classifications of cutting fluids. According to different processing techniques and requirements, there can also be other special types of cutting fluids. Choosing the right cutting fluid for specific machining conditions can ensure machining quality, prolong tool life and increase productivity.
