Haas’ TRT100 dual-axis trunnion table is designed for high-speed, accurate positioning for even the smallest machining centers. At less than 20” wide and 13” deep, the table can fit into nearly any machining center or can be mounted on one end of a larger machine’s table, freeing up the remainder for additional fixtures or vises. It also can be easily removed when not needed. Fast indexing speeds ensure short cycle times, and powerful brakes on both axes guarantee accuracy for 3+2 machining, Haas says.

Brushless servomotors provide 42 foot-pounds of spindle torque on the tilt axis and 20 foot-pounds on the rotary axis, with indexing speeds of 1,000 degrees/sec. on the tilt axis and 1,950 degrees/sec. on the rotary axis. The trunnion provides ±120 degrees of tilt and 360 degrees of rotation to position parts to almost any angle for machining. 

The trunnion’s precision-ground 100-mm platter features multiple bolt patterns and a precision through-bore for versatile fixturing, and will swing parts ranging to 8.4” in diameter. Maximum platter capacity is 20 lbs. A pair of user-configurable ports on the side of the trunnion table route air through the tilt axis to the rotary axis for operating pneumatic fixtures or other air-activated devices.
