ABSTRACT:
A rotary machining system is presented which uses a housing, a combined spindle and cutting disk, a source of high pressure fluid, a hydraulic line, a needle valve, a carbide ball and a carbide socket to machine superalloys and other difficult-to-machine materials and alloys at high speeds. The hydraulic lines and fluid source provide high pressure fluid through an aperture of the carbide socket into the housing to float the spindle. This fluid acts as a hydrostatic thrust bearing as it separates the spindle from the walls of the housing. Since the spindle and cutting disk are a single unit which are not physically attached to a roller bearing mechanism, they may be quickly and easily inserted and removed to minimize the "down time"0 of the system when the cutting disk needs to be replaced or ground to a sharp edge.
