Hydrostatic bearing oil film thickness control system

Hydrostatic bearing oil film thickness control system, to hydrostatic speed and volume of the composite support technical regulation technology, particularly, to a hydrostatic bearing oil film thickness control system. In order to solve the conventional hydrostatic bearing oil film thickness is not controlled, when the machine load or interference conditions or human factors produce changes in the hydrostatic bearing oil film thickness instability problems machining precision and efficiency of the impact, according to the present invention after treatment the actual film thickness and the signal processing by the DSP controller signal acquisition, and then find the deviation of the received signal to a predetermined film thickness, the final output signal to the CNC control system, the output of the CNC system speed control signal and a discharge the amount of control signals to the inverter and servo variable pump; oil system output flow achieved by adjusting the speed and displacement of the double efficient fast response control, and ultimately achieve the object of the hydrostatic bearing oil film thickness control, the present invention is applicable to a hydrostatic bearing vertical lathe.
