Adding a 4th-axis rotary table to a machining centre is a proven way to boost productivity, reduce setups, and increase accuracy on multi-op parts. Adding a fast rotary table to a fast machine creates a high-speed package that slashes cycles times even further.
The new HRT160SS super-speed rotary table from Haas Automation provides indexing speeds up to 570°/second to take advantage of the increased speeds and feeds of today’s high-speed machining centres. To gain the highest possible performance from the HRT160SS without sacrificing reliability or longevity, Haas engineers optimised oil patterns to reduce drag, modified the brake system for fasterresponse, and increased accel/decel rates to cut cycle times.
Designed to complement the high-performance Haas DT-1 Drill/Tap Centre, the HRT160SS ismore than four times faster than the standard HRT160 rotary table. With itscompact size, the HRT160SS easily fits into the work envelope of the DT-1, aswell as other compact machining centres.
Accurate MachiningThe 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 centre 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.
