Concentricity Matters
These spindle shafts for Haas HRT310 rotary tables are halfway through the machining process, and ready for op 2. The shafts are machined complete – turned, bored, drilled, and tapped – in two setups on Haas ST-40 turning centers with live tooling. The ODs are then precision ground for the worm gear and bearings. The worm gear is hobbed after it is attached to the spindle to ensure the utmost concentricity between the large diameter bearings and the worm gear.
