Haas Automation, Inc.
Perfectly Centered
These spindle shafts for HRT450 rotary tables are fresh off one of the precision OD grinders in the Haas Automation machine shop. Next, a large-diameter aluminum-bronze gear blank will be assembled to each shaft, and then each spindle assembly will be trammed-in on a CNC gear hobber to a maximum 2-micron runout before the worm gear is cut. Cutting the worm gear after it’s assembled to the spindle shaft ensures perfect concentricity of the gear pitch diameter to the bearing journals and the spindle axis.
