HRT450 Spindles
These high-precision spindles for Haas HRT450 rotary tables are being assembled with aluminum-bronze worm gear blanks, before heading to the CNC gear hobber. Each spindle will be trammed-in on the 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. The finished assemblies are then inspected on a Wenzel WGT500 CNC gear analyzer.
