ADVANCED MILL-TURN MULTI-TASKING MACHINES
In Booth S-8100, the all-new Puma SMX 3100 S Mill-Turn Multi-tasking Machine from Doosan Infracore Machine Tools (Pine Brook, NJ) will make its North American premier. 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 deg 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 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, X1, Z1 and Y, is 50/50/36 m/min. 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.
An overview and demonstration of the Puma SMX 2600/3100 Mill-Turn Multi-tasking Machine.
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.
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). www.doosanmachinetoolsusa.com

CYLINDRICAL GRINDING FOR SERIAL OR SMALL LOT PRODUCTION
In Booth S-9259, Fermat Group (Prague, Czech Republic), with the cooperation of Lucas Precision (Cleveland, OH) – the exclusive US importer of the Fermat machines – will not only display their highly customizable table type horizontal boring mill, but also their cylindrical grinder model BHC R, which is another product within Fermat’s extensive machinery line.
In earlier years, Fermat struggled to find a supplier of cylindrical grinders they felt could adequately meet the needs and tolerances of their high precision horizontal boring mill spindles. It was the decision of owner, Jiří Ferenc, to purchase a local Czech company that has produced the traditional style of cylindrical grinders for quite some time, and update their processes and technologies. Thanks to this decision, Fermat is now a top producer of cylindrical grinders within the European market. After establishing a presence across Europe, and even into Russia, Fermat has decided to expand their operations to the West by taking advantage of the service support and brand recognition that Lucas Precision offers.
On display will be Fermat’s cylindrical grinding machine, the Model-BHCR, which is designed for external and internal grinding operations. The program-controlled rotation of the grinding head along the vertical axis allows for sequential plunge grinding or longitudinal grinding with a moving table, and plunge grinding with a stationary or oscillating table. The workpieces are held in place by one of two methods: clamped between centers or by using a chuck (optional accessory). When a workpiece is clamped between centers the part can be cylindrically or conically ground with precise accuracy.
Interpolation of perpendicular axes using the longitudinal feed of the table (Z-axis) and the transverse feed of the grinding wheel (X-axis) provides a wide range of grinding operations with a dressed grinding wheel also available for external and internal grinding. The end surface of the workpiece can be ground by the side of the wheel which is an outstanding feature of the BHCR grinding machine. This machine is suitable for precise and efficient grinding of complex workpieces in both serial and small-lot production.
The technical parameters of the Model- BHCR grinder are:
Swing Ø | mm/in | 630; 850; 1000* | 24.8; 33.4; 39.3* |
Distance between centers | mm/in | 2000; 3000; 4000; 5000; 6000 | 78.7; 118.1; 157.4; 196.8; 236.2 |
Maximal weight of workpiece | kg/lb | 4,000; 5,000* | 8800; 1100* |
Maximal peripheral speed | m/s; ft/s | 50 | 164 |
Achieved accuracy | mm/in | 0.003 – 0.005 (0.002*) | |
Achieved roughness | Ra 0.2 (Ra 0.07*) |
Also on display will be the highly equipped and precise WFT 13R CNC table type horizontal boring mill, equipped with a 5 in spindle, X-axis table travel of 177 in (4,500 mm), Y-axis headstock vertical travel of 98 in (2,500 mm), Z-axis column travel of 59 in (1,500 mm) and W-axis spindle travel of 28 in (730 mm). The WFT 13R design also includes a V-axis ram travel of 27.5 in (700 mm) that provides a spindle support while reaching to the center of the table while maintaining rigidity.
A demonstration of the Fermat Table Type Horizontal Boring Mill WFT 13 CNC-Automatic Milling Head and Tool Exchange.
The WFT 13R model is equipped with a rotary table on a cross roller taper bearing. The table design includes two planetary gearboxes, two servomotors, and two pinions which operate in the master/slave relationship for extremely accurate positioning of the table. This arrangement prevents backlash, limits sticking issues and provides continuous B axis machining as a standard feature. Fermat and Lucas Precision will also showcase their new design on pallet exchange systems. Fermat’s “Speed Lock” system is fast, effective, and a very economical solution for customers with high volume production pieces without the cost and complexity of full pallet shuttle systems. This system limits the amount of time between set ups which increases efficiency and productivity.
This machine with immediate delivery from the show is equipped Fanuc 31i control system. The powerful headstock and main Fanuc spindle motor (37 kW/50 hp) of the WFT 13 is designed for rough machining with an emphasis on high quality machining surface finishes. A two speed gear box for increased spindle speeds is provided, allowing for maximum metal removal during heavy machining operations.
The show machine is also equipped with Fermat’s 105 station robotic automatic tool changer produced by German leader of robot industry, Kuka Robotics. The robotic tool changer is designed to exchange 105 tools minimum (based on design) into the working spindle of Fermat’s horizontal boring mills. The tools can be exchanged directly into the working spindle, or into a predefined position on an automatic milling head, which is an extremely beneficial feature of this design. The main advantages of the robotic tool changer is that it provides fast tool exchange times, and limits the amount of service or maintenance needs compared to the standard tool changer arrangement.
A wide selection of optional accessories such as facing heads, manual milling heads, and automatic milling heads are available to be integrated into the WFT 13R machine being presented at the show per customer request. lucasprecision.com, www.fermatmachinery.com
THE REINVENTION OF MODULAR MACHINING
In Booth S-9059, the DLFn from Fuji Machine America Corporation (Vernon Hills, IL) displays a completely innovative approach to flexible line configuration that allows for easy addition or changeover of modules for extreme efficiency. Raw materials go into the DLFn for turning, measuring, drilling, deburring, parts cleaning and other operations, and then exit as a finished part. DLFn internal work handling units allow for fully automatic line configurations. Switching operations requires simply pulling out one module and replacing it with another. Two machine modules can be set on one standardized base module, allowing for flexible processing. The pull out design of the DLFn also allows for convenient access during maintenance. www.fujimachine.com
