Convert three axes to five

Five-axis machining provides maximum flexibility and is useful for complex tool fabrication, but its high cost prohibits its use in many smaller shops. Now, a new dual-axis trunnion rotary table can convert a three-axis mill into a high-performance five-axis center with minimal installation and cost. The TR160, TR210, and TR310 dual-axis trunnion rotary tables bolt onto most three-axis centers with 160-, 210-, or 310-mm platters.The TR Series allows a toolmaker to position workpieces at almost any angle for multisided machining. Brushless servomotors power both axes and allow ±120° tilt on the a-axis and 360° rotation on the b-axis. The precision-ground platters are made from heat-treated 4140 alloy steel, and they use six standard T-slots measuring .625 inch that are equally spaced at 60° to ease fixturing. With three servocontrol configurations, the TR Series can interface with almost any machine.
The smallest unit, the TR160, has a footprint of 39 by 14 inches, with maximum part capacity of 80 lb and part swing of 17.5 inches. The TR210 can handle 200 lb with a 23.5-inch swing, and the TR310 goes up to 500 lb and 31 inches of swing. Respective platter speeds are 80°, 60°, and 50°/sec.
