The main spindle uses an A2-8 nose with a 3.03 in hole through spindle, and runs on two ranges: 35-1,050 rpm (low) and 35-3,500 rpm (high). The main drive motor is rated 30 hp. Tooling is held in a 12-station drum-type turret, with a maximum boring-bar diameter of 1.75 in. Standard equipment includes a 12 in 3-jaw hydraulic chuck, a programmable tailstock, and a chip conveyor, with a Fanuc Series O-T CNC control.
