Abstract Based on the“disassembling toy bricks”mechanics model and the bearings’stiffness matrix which is built by simulated static mechanics，the structure design of the m achine—tool spindle was optimized． The calculational task was considerably reduced by the proper mathematical transformation． It was verified to be available for machine—tool spindle’S volume and stiffness’S optim izing design through the analyses and calculations of various m achine—tool spindle systems．The result of this paper was tested on the M 21 IOA inner—grinding machine．
