The Haas GT Series Lathes Have Small Footprint
Versatile, second-operation machines can handle high power and are affordable.
| Published June 27, 2008
The GT Series lathes from Haas Automation, Inc. (Oxnard, CA) are small-footprint production machines designed to fulfill short-run, multiple-op work for small- to medium-sized shops that need versatile, second-operation machines that can handle high power and a wide range of speeds at very affordable prices.
The compact GT-10 and GT-20 are suitable as "chucker" lathes for shops where space is at a premium. The GT-10 has a 10 x 8-in. maximum capacity, with part swings of 16.25-in. over the front apron and 12.75-in. over the cross slide. The GT-20 offers an 11 x 12-in. maximum capacity, with part swings of 13-in. over the front apron and 9.25-in. over the cross slide.
Both GT machines are equipped with a powerful Haas-designed vector drive spindle (7.5 hp for the GT-10; 20 hp for the GT-20) that provides high torque and a wide constant-power band. Rapids of 710 ipm and a high-speed cross slide yield short cycle times.
In base configuration, the GT Series machines have a maximum speed of 3000 rpm, and do not include a chuck, hydraulic system or tool turret. An optional pneumatic chucking clamping system is available for the GT-10, and a high-productivity hydraulic chucking system is available for the GT-20.
High-productivity options include the Haas Intuitive Programming System, 2-position quick-change tool posts for 0.75-in. tools, a high-volume coolant system, user-definable macros and expanded program memory to 16 MB.
