Study on the hot deformation for workbenchsupported by hydrostatic guideway of vertical lathe

Application of Hydrostatic Guideway Supplying with Constant Oil Flow on Heavy Duty Machine Tool;

In this paper,the working principle as well as the type,the advantages and disadvantages of hydrostatic guideways are discussed in detail.

Using new technologies of static pressure bearing, static pressure guide and gas bearing, the mold of fresnel lenses mirror was precisely manufactured.

Control Schemes of Oil Film Thickness for Hydrostatic Slide;

The control of oil film thickness for hydrostatic slide is necessary improved the performance of movement precision and low-speed stability effectively when the load of hydrostatic slide is time-varied.

The paper introduces the qualitative, quantificational analysis and calculation of the of load capacity and stiffness for contrapositive hydrostatic pocket of hydrostatic slide in precision and ultraprecision machine, and brings forward the method of optimization calculation.

Those methods mainly inlcude applying multi throttle air lubricated hydrostatic slide guide and mounting a float unit on the screw pair.
