Abstract: In one embodiment of saw tooth assembly, the tubular saw tooth is releasably inserted with friction fit inside the hollow of a tubular mount. In an alternate embodiment, it is the tubular mount which is releasably inserted with friction fit inside the hollow of the tubular tooth. In both cases, the hollows of the mount and tooth are coextensive, whereby a common axial through-channel is defined. The tubular mount is to be anchored to the peripheral edge of a circular saw discoid plate. The wood chip generated during circular saw operation can therefore freely engage through the common through-channel, i.e. through the whole saw tooth assembly, and escape therefrom. Wood chip clogging of the saw tooth during sawing operations is therefore substantially prevented, and the aerodynamic features of the circular are accordingly enhanced.

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.
