Haas Expands Five-Axis Machining Line
November 29, 2010—Five-axis machining is becoming more common today as a means to reduce set-up time and increase accuracy for complex parts. But investing in a five-axis machine tool can be prohibitively expensive, especially for smaller shops. Haas Automation recently introduced the TR160Y dual-axis trunnion rotary table that puts five-axis capabilities well within reach of the average job shop, and its compact size provides greater mounting flexibility. The TR160Y is designed to mount in the Y direction (front to back on the table) of a mid-size VMC. At less than 25" wide and only 20" deep, the TR160Y easily fits on one end of the machine’s table, freeing up the remainder for additional fixtures or vises. The TR160Y has a 160 mm T-slot platter, and will swing parts up to 7.5" diameter. The maximum platter capacity is 80 lbs. The trunnion provides ±120 degrees of tilt and 360 degrees of rotation for full simultaneous five-axis motion, or to position parts to almost any angle for machining. Like all Haas rotary tables, it can easily be removed when not needed. Powerful brushless servomotors provide 150 ft-lb of spindle torque on both axes of the TR160Y. Brake torque is 300 ft-lb and 100 ft-lb respectively, and speeds are 130 deg/sec on the rotary axis and 100 deg/sec on the tilt axis. The trunnion’s precision-ground platter of heat-treated 4140 alloy steel has six standard 5/8" T-slots equally spaced at 60 degrees for easy fixturing. Three servo-control configurations are available, making the TR160Y easy to interface to almost any machine.
