The Haas Tri60Y dual-axis trunnion rotary table is a five-axis machine with a compact footprint. The machine is designed to mount in the Y direction (front to back on the table) of a mid-sized VMC. The 25" × 20" table features a 160-mm T-slot platter and can swing parts as large as 7.5" in diameter. The maximum platter capacity is 80 lbs. The removable trunnion provides ±120 degrees of tilt and 360 degrees of rotation for full, simultaneous five-axis motion to position parts at virtually any angle for machining.
Brushless servomotors on both axes of the table provide 150 foot-pounds of torque on the A axis and 100 foot-pounds of torque on the B axis. Brake torque is 300 foot-pounds and 100 foot-pounds, respectively, and speeds are 130 degrees per second on the rotary axis and 100 degrees per second on the tilt axis. The trunnion’s precision-ground platter of heat-treated 4140 alloy steel has six standard 5/8" slots that are equally spaced at 60 degrees for fixturing. Three servo control configurations are available, allowing the table to interface with virtually any machine, the company says.
