Development and application of green cooling technology
In metal cutting, the cutting fluid mainly cools, lubricates, cleans and removes chips, and prevents rust. It also improves processing efficiency and processing quality and reduces costs. However, with the development of the economy and the increasing awareness of environmental protection, the negative effects of cutting fluid are gradually exposed: (1) Pollution environment to improve the performance of cutting fluid, cutting fluid
