The Haas HRT-800 is an extra-large CNC rotary table with a reputation for plug-and-play 4th-axis machining that has made the Haas HRT series the standard rotary platform in Haas-equipped shops. This 2022 unit carries an 800 mm (31.5 in) platter with eight T-slots at 45 deg, supporting workpieces up to 3,746 lbs with support and 1,873 lbs unsupported - capacity built for large fixtures, weldments, and aerospace-class parts. The spindle delivers 1,200 ft-lbs of continuous torque with 8,000 ft-lbs of brake torque at 100 PSI, a 40 deg/sec maximum speed, +/- 15 arc-sec indexing accuracy, 10 arc-sec repeatability, and 0.001 deg resolution through a 118:1 gear ratio. A 14 in pilot bore and 20.5 in center height handle long workpieces and special fixture-locating requirements in the vertical mounting configuration. This unit is optioned with Direct Control by the mill CNC for full 4th-axis interpolation, Sigma 5 servomotors, a 30 mm toe clamp kit, and rotary cable support, and runs on standard 115 VAC power. Compared with the smaller Haas HRT630 in the same extra-large rotary line, the HRT-800 steps up from a 630 mm platter to a full 800 mm platter and raises continuous torque from 1,025 ft-lbs to 1,200 ft-lbs, opening the door to bigger fixtures and heavier parts than the smaller table can carry. Against bolt-on third-party rotary packages, the Haas-native design connects directly to the Haas mill control - no external servo amplifier integration, no custom post work - so 4th-axis capability comes online the day it lands on the floor. For a shop running large parts on a Haas VS-series or other 4th-axis-ready Haas mill, the HRT-800 is the direct path to large-envelope rotary work.
