Abstract

In high precision machining and grinding applications, high-stiffness, high-load capacity work-head spindles and rotary tables with nanometer-level error motions are becoming more necessary. The combination of reasonable load capacities and 10,000 RPM maximum speed make the Professional Instruments Company model 4R BLOCK-HEAD® air bearing spindle a first choice for many high-accuracy applications. However, there are applications requiring moreload capacity in the same package size, making high pressure oil hydrostatic a logical candidate. The present work describes the design and testing of a step compensated oil hydrostatic spindle consisting of two conical bearing surfaces (bi-conic) with high load capacity-ideal for the rigorous demands of precision machining and grinding. The most compelling argument for this oil hydrostatic spindle is the combination of nanometer-level error motions and near indestructibility.
