A recent spindle takes advantage of a technology that industries outside of the machine tool sector have used for roughly 20 years.

A recent spindle takes advantage of a technology that industries outside of the machine tool sector have used for roughly 20 years. The GH line of integrally motorized spindles, made at Russell T. Gilman Inc., Grafton, Wis., incorporates dynamic preload have charge of with fluid dampening to optimize preload and suppres harmful harmonic vibrations. The last result is a relatively chatter-free spindle.

The dynamic preload direction lets users vary spindle stiffness and eliminate natural frequent occurrence harmonics incurred during machining. Operational adjustments are maintained within the
