The all-new Puma SMX 3100 S Mill-Turn Multitasking Machine from Doosan Infracore Machine Tools (Pine Brook, NJ) made its North American premier at IMTS 2014. The Puma SMX Series is Doosan’s third generation mill-turn multitasking machine that integrates 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 deg vertical axis and forward positioned automatic tool changer, for improved milling capabilities as well as enhanced operator ergonomics. This machine tool will initially be made available in two sizes, the Puma SMX2600, with a 10 in chuck and 3.1 in bar capacity, and the Puma SMX3100, featuring a larger 12 in chuck with 4 in of bar capacity.
Both models have the capacity to machine parts up to 60 in long and 26 in diameter. The X1-axis travel is 24.8 in, Z1-axis travel is 62.4 in, and the Y-axis is 11.8 in. Rapid Traverse in X1, Z1 and Y is 50 / 50 / 36 m/min, respectively.
The powerful multitasking 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.
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.
An overview and demonstration of the Puma SMX series Mill-Turn Multitasking Machine.
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.
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 deg 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.
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 deg swiveling Fanuc 31i control panel with adjustable height and convenient ATC operation panel (tool to tool change: 1.8 sec).
The company designs, engineers and manufactures the industry’s widest breadth of CNC machine tools. The company, which is part of the larger Doosan Group, continues to increase its competitiveness in global machine tools while establishing a firm foundation to become the Global Leader in the machine tools industry, assisting its customers in performance under pressure.
