What the maker publishes about the current Haas ST-20Y

Haas files the ST-20Y under Y-axis turning centers in the ST Series; its Y stroke is ±2.0 in. X moves 8.40 in and Z moves 22.50 in. On X and Y the rapid rate is 472 ipm, while Z rapids at 945 ipm. A 12-station turret takes BMT65 live tools that spin up to 4000 rpm. The main spindle gains a C axis rated 5.0 hp, turning at up to 60 rpm and positioning to 0.01°. A brake holds that C axis with 250 ft-lbf. The spindle reaches 4000 rpm from 20.0 hp, and at 500 rpm it produces 150.0 ft-lbf. The nose is A2-6, the chuck 8.3 in and the bore 3.50 in, which passes bar up to 2.50 in. The swing limit is 21.0 in, and the BMT65 turret cuts diameters to 11.75 in. Cutting length reaches 22.5 in depending on workholding.
