A heavy-duty, 40,000-rpm spindle using HSK toolholders is now available on Datron Dynamics’ (Milford, NH) line of vertical machining centers for high-speed applications, such as engraving and marking in a wide range of light and heavy metals and plastics. The HSK spindle is used for precise cutting at high speeds up to 40,000 rpm. The superior run-out accuracy and stability of the toolholders ensure reliable, accurate cutting. They are ideally suited for Datron’s machining centers featuring intelligent probing capabilities. The radial rigidity and clamping force of the toolholders have been optimized with a concentricity of less than 3 microns. The larger diameter toolholders have been field-proven to improve rigidity and resist radial forces. A special chamber system, filled with thermosetting plastic, has vibration-dampening properties, resulting in better surface finishes and tool life extension. Users report that higher cutting feed rates are possible for roughing and finishing operations with the new spindle/toolholder option.
