The 8" and 10" Puma GT2100 series turning centers from Doosan are said to incorporate key features of the company’s Puma 240, but in a more compact and cost-competitive package, with improved performance, accuracy and reliability.

The machines each feature a 23.6" swing-over bed and 15.4" swing-over saddle. Maximum turning diameter is 15.4", maximum bar working diameter is 3.2", and maximum turning length is 22.1". The 30-degree single-piece slant bed is designed to reduce the center of gravity of both spindle and cross-slide. In addition, the company says the amount of structural vibration, or natural frequency (NF), which affects the machine’s contouring performance and surface finishes, is 42 percent higher, delivering greater dynamic stability in high-speed operation. According to Doosan, cast design optimized with 3D computerized analysis delivers stable cutting performance with minimized cutting vibration and extended tool service life. Wide ribs and a box-type slideway further reinforce bed rigidity.

An optimized spindle overhang design is said to minimize the rotational inertial load, enhance rigidity and shorten acceleration/deceleration time. The GT series offers a 25-hp spindle motor, maximum spindle speed of 4,500 rpm, and rapid travels of 945 ipm in the X axis and 1,181 ipm in the Z axis.
