A New Method for Improving Mechanical Properties of Hydrostatic Guide-way

Shi Enxiu;Guo Pengge;Wang Hailong;Xi'an University of Technology;  
Carrying capacity and oil-film stiffness of hydrostatic guide-way are two important technical parameters.In order to meet the requirements of high precision CNC machine tool for hydrostatic guide-way,a new type hydrostatic guide-way with high liquid resistance was put forward based on local pressure loss theory.The simulations were done,which showed the effects of the position,width and depth of oil ring at resistive oil edges of the new hydrostatic guide-way on the oil chamber pressure.It is shown from the results that oil chamber pressures of hydrostatic guide-way may be enhanced significantly if the position,width and depth of the oil ring at resistive oil edges are appropriate.It is verified that the carrying capacity and oil-film stiffness of the new type hydrostatic guide-way with high liquid resistance are improved through the experiments.
