Haas Automation (Oxnard, CA) has added a fourth-axis rotary table that provides indexing speeds up to 570°/second to take advantage of the increased speeds and feeds of today’s high-speed machining centers. To gain the highest possible performance from the HRT160SS without sacrificing reliability or longevity, Haas engineers optimized oil patterns to reduce drag, modified the brake system for faster response, and increased accel/decel rates to cut cycle times.


Designed to complement the high-performance Haas DT-1 Drill/Tap Center, the HRT160SS is more than four times faster than the standard HRT160 rotary table. With its compact size, the HRT160SS easily fits into the work envelope of the DT-1, as well as other compact machining centers.


The HRT160SS is driven by a high-torque brushless servomotor that provides 150 ft-lb (203 Nm) of spindle torque for synchronous 4-axis machining, and it has a pneumatic brake that yields 100 ft-lb (136 Nm) of holding torque for stationary work. Indexing accuracy is ±15 arc-sec, with repeatability of 10 arc-sec. The 6.3" (160 mm) platter of the HRT160SS has a center height of 5" (127 mm), and a 1.5" (38 mm) diameter through-hole. Six radial T-slots simplify fixture and workpiece mounting, and both manual and pneumatic tailstocks are available for additional workpiece support.
