Why Should Use Cutting Fluid In CNC Machining?

DALIAN, China - July 18, 2022 - PRLog -- Function Of Cutting Fluid

1. Lubrication:

Cutting fluid can form an oil film on the surface of workpieces and tools, and can penetrate into the smallest metal gaps and irregular places to reduce the friction between metals. The following effects can be achieved:

① Reduce tool wear and prolong tool life.

② Reduce the cutting resistance and use less power for machining.

③ Prevent burrs on the edges and improve the accuracy of the machined surface.

2. Cooling

The cutting fluid can reduce the heat generated in the cutting operation, and its temperature can be as high as 600-1000 ℃. Especially for workpieces with low thermal conductivity such as stainless steel, it is difficult to dissipate heat, and the workpieces will become hot.

Using cutting fluid to reduce the temperature can bring the following effects:

① The thermal deformation of the cutter is reduced and the service life of the cutter is prolonged.

② The machining accuracy is stabilized by preventing thermal deformation of workpiece and tool.

③ High speed machining is realized.

3. Cleaning

Spraying cutting fluid can wash away the chips generated in the cutting process and clean the workpiece, which can bring the following effects:

① Prevent the workpiece from scratching due to chip adhesion.

② Prevent machining defects caused by chip blockage and accumulation.

③ Prevent tool breakage due to chip entanglement.

Classification Of Cutting Fluids

Cutting fluids can be roughly divided into two types: insoluble and water-soluble. Insoluble cutting fluids can be used directly, focusing on lubrication (and a few on cooling). Water soluble cutting fluid is usually diluted with water and used for cooling.
