High-speed cutting and milling machine, according to different raw materials, fineness requirements and product use, can be adapted to differ- ent grinding fineness of micro-cutting tool assembly. The high-speed rotating knife of the product to be treated makes the material rotate at a high speed in the head of the micro-cutting tool. Under the push of centrifugal force, the product will pass the cutting edge of the micro-cutting tool and contact the static blade set outside, and the two will process the product at a high speed like scissors
