Power And Versitility In A Small Footprint

The GT-20 lathe from Haas is designed to deliver high power and a high range of speeds in a small footprint production machine. The lathe takes up 8' × 4. 5' of floor space, yet offers an 11" × 12" maximum capacity, making it an especially useful "chucker" lathe for shops where space is at a premium.

The GT-20 lathe from Haas is designed to deliver high power and a high range of speeds in a small footprint production machine. The lathe takes up 8' × 4.5' of floor space, yet offers an 11" × 12" maximum capacity, making it an especially useful "chucker" lathe for shops where space is at a premium. The machine provides a maximum part swing of 13" over the front apron, with a 9.25" swing over the cross slide. The X axis provides 6" of travel with 2,400 lbs or thrust, and the Z axis provides 12" of travel with 3,700 lbs of thrust.

The 20-hp (peak) vector dual-drive system gives the lathe spindle speeds up to 4,000 rpm (with hydraulic chuck option), and peak-torque of 154 foot-pounds. On-the-fly wye/delta switching delivers higher torque and a constant power band for constant surface speed cuts.

The base configuration of the machine has a maximum speed of 3,000 rpm and does not include a chuck, hydraulic system or tool turret. The machine's A2-6 spindle nose has a 3" bore and accepts a variety of optional through-hole chucks and collets. The cross slide accepts gang-style tooling.
