Project introduction:

Achieving the goals of carbon peaking by 2030 and carbon neutrality by 2060 is not only a solemn commitment made by China, but also key research that China is currently working on.Achieving the ‘dual carbongoals’ will become a hard constraint for the development of local governments and enterprises, and it will also bring new opportunities and challenges to the machinery manufacturing industry.

This project combines eddy current cooling and electrostatic lubrication to achieve refrigeration and lubrication during processing by the same device, so as to improve processing quality without causing environmental pollution.The main research contents of the project include: on the basis of analyzing the mechanism of dry cutting lubrication, design a dry cutting lubrication structure with both electrostatic lubrication and eddy current cooling, and study the structural parameters through simulation on the discharge performance, ozone concentration and cooling effect of the system. After the structural optimization design, manufacturing experiments were carried out to verify the effectiveness of the proposed dry cutting lubrication technology.

The technology has already passed the first-stage principle prototype and cutting effect test, which has verified the effectiveness of the dry lubrication technology. Currently, the internal cooling lubrication tool holder structure is being designed to further improve the dry cutting lubrication effect.After the dry cutting lubrication technology has been tested and passed the promotion, it can partially or completely replace the cutting fluid for dry cooling and lubrication, which reduces the production cost of enterprises, and can also improve production efficiency and environmental protection benefits.
