Abstract
An improved high-speed spindle assembly for a shank-driven cutting tool comprises a hollow spindle for a collet, a titanium alloy drawbar within the spindle for threadingly engaging the collet, and a tubular resilient member within the spindle surrounding the drawbar for damping vibrations. A transverse resilient member in a threaded portion of the collet resists rotation of the collet on the drawbar. A ten-tooth involute spline provides precise sliding engagement of the drawbar within the spindle. A pair of ball bearings are axially clamped to the spindle by a pair of titanium nuts, a lower nut having a flange closely spaced from an external annular surface of a spindle housing for excluding foreign matter, an upper nut having a cavity for axially retaining a flange of the drawbar.
