The new NBV vertical machining center from MAG Industrial Automation is flush with modular application flexibility, including configurations for 3-, 4-, and 5-axis contouring or 5-axis mill/turn work, integrated CAM support and program simulation and four spindle options ranging up to 42,000 rpm, according to the company's press release.  In addition to its hydraulic-free design, the NBV conserves energy with a selectable ECO-Mode power saving feature that automatically levels speed and acceleration for a balance of cutting performance, energy use and machine-component life. Applications include die/mold, automotive and aerospace impellers and blisks, medical, and general machining.

In a footprint of just 9.6 m² (133.5 sq ft), the fixed-table NBV 400 provides X-Y-Z ranges of 700 x 600 x 500 mm (27.6 x 23.6 x 19.7 in), with table capacity of 300 kg (661 lb). Spindle options include speeds of 10,000, 12,000 (mill-turn only), 18,000, 24,000 and 42,000 rpm, offering a torque range of 125 to 12.4 Nm (92 to 9 lb ft) at 40 percent duty. A disc-type 40-tool magazine integrated in the machine bed maximizes in-cut time with fast direct tool change (4.4 sec chip-to-chip), without a separate tool changer. The hydraulic-free system clamps tools with proven disc springs.

FEA-optimized for static and dynamic stiffness, the NBV is built on a single-piece cast machine bed that provides high rigidity and vibration damping for outstanding cutting performance and precision in heavy machining operations. High-performance machining is achieved with direct-coupled digital drives, delivering rapid traverse rates up to 60 m/min (2362 ipm) and acceleration up to 6 m/s² (19.7 ft/s²). An NC tilting/rotary table provides optional A and C axes with ±5 arc second accuracy, minimizing movement of the linear axes in contour machining. The mill-turn version includes a 1000 rpm C-axis table as well.

Control options for the NBV 400 include Siemens, Bosch Rexroth, Fanuc and Heidenhain. The NBV 400 is a self-contained unit, making for easy transportation, rigging and setup. Automation and other processing options, including MQL/dry machining, robot load/unload systems and additional tool-disc magazines, are easily integrated.
