Turning diameter and X rapid. The ST-30 turns 15 in (381 mm) and rapids at 945 ipm (24 m/min) on both axes. The ST-30Y turns 13.75 in (349 mm), and its X and Y rapids are 472 ipm (12 m/min). Z travel of 32.5 in (826 mm), the chuck, bar capacity and the 30 hp (22.4 kW) spindle are unchanged.
A 6.5 in (165 mm) chuck on an A2-5 nose, 4,100 rpm maximum, 3,400 rpm maximum when synchronised with the main spindle, and a 2.31 in (58.7 mm) bore. The chuck throat is 1.81 in in diameter by 1.6 in deep (46 mm by 40.6 mm). The integrated brake holds 17 ft-lbf (23 N·m), orientation accuracy is ± 0.02° and rapids are 400 ipm (10 m/min).
It depends on whether diameter or bore matters more. The ST-28Y passes 4 in (102 mm) bar through a 4.62 in (117.3 mm) bore and has 40 hp (29.8 kW), but turns 11.75 in (298 mm) by 22.5 in (572 mm). The ST-30Y passes 3 in (76 mm) bar, has 30 hp (22.4 kW), and turns 13.75 in (349 mm) by 32.5 in (826 mm).
Live tools run to 4,000 rpm on BMT65 tooling. The C axis runs to 60 rpm, with a 5 hp (3.7 kW) maximum rating and 0.01° positioning, and Haas lists its control type as interpolated motion and positioning. The C-axis brake is 13.9 in (353 mm) in diameter and holds 250 ft-lbf (339 N·m).
Haas lists WiFi, HaasDrop wireless file transfer, Safe Run and HaasConnect remote monitoring as standard on the ST-30Y. The two-stage automatic parts catcher, sub-spindle and automatic door are options. The feature list also cites new castings with increased rigidity and damping, and improved chip evacuation.
