Research on Block Thin Film Hydrostatic Guide Rail of Precision Grinding Machine for Optical Manufacturing

2MK-1760 is a grinding machine used in large scale optical lens manufacturing. To meet the manufacturing requirements, the block thin film hydrostatic guide rail is applied. In this paper, the structure of block thin film hydrostatic guide rail is proposed. In order to get the thickness and the stiffness, design calculation is performed. Experiments are carried out to verify that the feasibility and the validity of this technique.
