Three main functions of cutting fluid in the processing of precision parts

The cutting fluid has three main functions of cooling, lubricating and cleaning during the processing of precision parts.

Cooling: The vaporization of the cutting fluid at the contact point between the tool and the workpiece during the processing of precision parts can remove the cutting heat from the junction of the tool and the workpiece, can remove most of the heat in the processing process, and reduce the tool and the workpiece. The indirect contact temperature prolongs the service life of the tool, and prevents the precision error caused by the overheating deformation of the workpiece and the tool.

Lubrication: During the cutting process, the cutting fluid can penetrate between the workpiece and the tool, reducing the friction between the tool and the chip and the processed surface, so that a thin adsorption film is formed in the tiny gap between the chip and the tool, reducing To reduce the friction coefficient, reduce the temperature of the friction part between the tool and the workpiece and the degree of wear of the tool, reduce the cutting force and cutting heat, reduce the wear of the tool and improve the accuracy of the workpiece.

Cleaning: During the processing of precision parts, the cutting fluid is often required to have a good cleaning effect. It is responsible for cleaning the fine chips, iron powder and sand from the machining process. The permeability and cleaning performance are one of the important standards that determine the excellent cutting fluid.
