The origin of ultra-high speed grinding process,the development and present sit uation of ultra-high speed grinding were summarized. The advantages and several characteristics of ultra-high speed grinding were summarized. The applications of high-efficiency deep grinding,precision ultra-high speed grinding,ultra-h igh speed grinding for difficult-to-grind materials and its green-machining properties were introduced. High-speed grinding and ultra-high speed grinding are advanced process technology. It can raise grinding efficiency and reduce wo rk surface roughness and can raise machining quality of the parts. Ultra-high s peed grinding can get across grinding 'heat channel', reduce grinding heat of introduction workpiece,consequently avoid or reduce grinding 'burn out' and pr oduce work surface with remains press stress. Ultra-high speed grinding may rea lize the ductility grinding for harden brittle materials. It also has good grind ing performances for high plastic materials and difficult-to-grinding material s.
