Haas equips the ST-20, a turning center in its ST Series, with an 8.3 in chuck, mounted on an A2-6 spindle nose. Bar work passes up to 2.50 in through a spindle bore of 3.50 in. The spindle runs to 4000 rpm and is rated 20.0 hp; torque peaks at 150.0 ft-lbf, reached at 500 rpm. Parts may swing up to 21.0 in. The turret choice governs cutting diameter: 13.00 in for BOT tooling, 11.75 in for BMT65 and 11.80 in for VDI. Maximum cutting length, which varies with workholding, is 22.5 in. X travel measures 8.40 in and Z travel 22.50 in, and both axes move at 945 ipm in rapid. The turret has 12 stations. WiFi comes standard, and an auto door is optional. Coolant capacity is 55 gal.
