• cool down

    It takes away a large amount of cutting heat, reduces cutting temperature, improves tool durability, reduces thermal expansion of workpieces and tools, and improves machining accuracy.

  • lubricating
    Reduce the contact between the tool and the workpiece → high temperature and high pressure, obtain hydrodynamic lubrication through the cutting fluid, and avoid wear on the machined surface of the workpiece caused by high temperature and metal collision.
  • Clean
    Clean the adhered debris and grinding powder, reduce the wear of tools and grinding wheels, and prevent scratches on the surface of the workpiece and the machine tool guide surface.
  • Anti-rust
    Reduce the corrosion of machine tools, cutting tools and workpieces caused by surrounding media.
