All-New Multi-Tasking Machine Offers Rigid 90° Vertical Axis for Improved Milling Along With Enhanced Operator Convenience

Doosan's all-new Puma SMX 3100 S Mill-Turn Multi-tasking Machine will make its North American premier at IMTS 2014.

The Puma SMX Series is Doosan's third generation Mill-Turn Multi-tasking Machine, integrating the capabilities of a vertical machining center and horizontal turning center into one platform. The Puma SMX Series distinguishes itself with a more rigid 90° vertical axis and forward positioned automatic tool changer, for improved milling capabilities as well as enhanced operator ergonomics.

The Puma SMX Series will initially be made available in two sizes, the Puma SMX2600, with a 10" chuck and 3.1" bar capacity, and the Puma SMX3100, featuring a larger 12" chuck with 4" of bar capacity.

Both Puma SMX models have the capacity to machine parts up to 60" in length and 26" in diameter. The X1-axis travel is 24.8", Z1-axis travel is 62.4" and the Y-axis is 11.8". Rapid Traverse, X1, Z1 & Y: 50/50/36 m/min.

Higher Productivity

The powerful multi-tasking functions decrease the total processing time and number of machining operations by using a single setup. This provides excellent high-speed performance for component manufacturing processes that require accurate and complex machining capabilities for turning, milling and secondary operations using the SMX sub-spindle, which is optional.

Machine Construction

The Puma SMX Series provides excellent performance for high precision machining by use of a high-rigidity machine construction using finite element analysis (FEA) in structural design and minimizing thermal deformation via oil cooler and an accuracy control feature based on multiple thermal compensation functions. The Y-axis machining area has been maximized through orthogonal design.

Ergonomic design enhances operator convenience, and efficient maintenance provides an optimal solution that meets customer needs.

Enhanced Precision

High accuracy control functions maintain excellent precision during long-term machining processes by minimizing the thermal deformation of the spindle and the feed axis, and by maximizing the precision through the 0.0001° B-axis and C-axis. Oil cooler minimizes thermal deformation of the spindle and feed axis and high-rigidity and high precision are achieved through the use of roller-type linear motion guides on all carriages.

Easy and Convenient Operation

Ergonomic design features easy access for maintenance as well as optimum operator convenience by including customized functions -- including front located tool magazine (80 tools max), side-to-side movable, 85° swiveling Fanuc 31i control panel with adjustable height and convenient ATC operation panel (tool to tool change: 1.8 sec).
