What is cutting fluid and is it harmful to human body?

Cutting fluid is an industrial liquid used to cool and lubricate tools and workpieces during metal cutting and grinding. The smog caused by cutting fluid is harmful to health.

Tao Huaqiang, technical inventor and general manager of Beijing Jinghanlin Mould Manufacturing Co., Ltd. said: "Environmental protection has always been a difficult problem hanging over the use of cutting fluid. The working environment is smelly, and the smog is harmful to health. In addition, if the deteriorated cutting fluid is not treated, it will cause greater environmental disasters to soil rivers. "

The role of cutting fluid:

1, cooling

The cooling function of cutting fluid is to take the cutting heat away from the tool (or grinding wheel), chips and heated workpiece through convection and vaporization, thus effectively reducing the cutting temperature, reducing the thermal deformation of the workpiece and the tool, maintaining the hardness of the tool and improving the cutting efficiency.

Step 2 clean

The surfactant of water-based cutting fluid has a good cleaning effect because it can form an adsorption film on the surface to prevent particles and sludge from adhering to workpieces, tools and grinding wheels. At the same time, it can penetrate into the interface between particles and sludge, so that it can be separated from the interface and taken away with cutting fluid to keep the interface clean.

3. Rust prevention

In the process of metal cutting, the workpiece will contact with corrosive media such as environmental media and cement produced by the decomposition or oxidation of cutting fluid components, and the surface of machine tool parts that contact cutting fluid will also be corroded accordingly.
