대고속전주축주축지탱방안진행분석，제출재고전속、대부하공황하，수윤활동정압활동축승시일충가행적주축지탱해결방안；병종제고주축강도、조니화회전정도등각도출발，선택료량충가용우수윤활적축승적필배재질，위전주축주축지탱설계제공삼고。
The high-speed electric spindle supporting schemes were analyzed. At high speed,high load conditions,water lubri-cated hydrostatic bearing was put forward as a kind of feasible spindle support solution. In order to improve the stiffness,damping and spindle rotary precision,two kinds of matching materials were chosen for water lubricated bearing. It provides reference for electrical spindle supporting design.
