A Solid, Robust Design
Constructed of heavy-duty materials and designed for dependable day-in, day-out operation, Haas rotary products are the benchmark by which all others are measured. We manufacture all critical components in-house at our state-of-the-art California facility. At the core of every Haas rotary table is a large-diameter, aluminum-bronze worm gear meshing with a ground alloy steel worm (hardened to 60 Rc) submerged in a synthetic oil bath. To ensure indexing accuracy, we cut the worm gear while it’s attached to the spindle, rather than assembling the finished worm gear to the spindle, as other manufacturers do. Each assembled spindle is trammed-in on a CNC gear hobber to a maximum 2-micron runout, and then the worm gear is precision cut. This guarantees the utmost concentricity between the large-diameter ball bearings and the worm gear, ensuring many years of smooth, extremely accurate, and bind-free operation.
