NVX5000 Series VMCs

July 01, 2011

DMG/Mori Seiki USA is now taking orders for the NVX5000 Series of high-precision vertical machining centers with a No. 50 taper spindle variation. The NVX5000 Series provides options and applications equivalent to those of the NV5000 Series (that sold more than 8,000 units) while achieving high levels of rigidity, thermal displacement stability and energy saving. And now, in addition to the No. 40 taper spindle specifications that were previously offered, Mori Seiki will expand the product line-up with a No. 50 taper spindle.

The main benefits of the No. 50 taper spindle specifications for the NVX5000 Series include: high precision, high rigidity, expansion of machining variation, energy saving, a high-performance operating system and high investment value. The NVX5000 minimizes thermal displacement by employing a heat-symmetrical structure in addition to offering optional coolant circulation inside the spindle, column and the castings of the bed. Compared with conventional machines, machining accuracy has been doubled through suppressing thermal displacement to less than half and improving the responsiveness of minimal feed. The accuracy of microfabrication has further improved by 100 percent, as microfabrication requires high accuracy, even on high rigidity machines with No. 50 taper spindles.

The NVX5000 Series boasts high rigidity in part due to the slideways on all axes, as well as from spindle bearing inner diameters up to 4.75", which is the largest in its class. No. 50 taper spindle specifications also include a high output motor with 30/22 kW (25 percentED/cont.). The machine's overall high rigidity and high output/high rigidity of the spindle have additionally improved heavy cutting ability by 30 percent.

The X-axis stroke is available in three variations (23.6", 31.5", 41.3"), allowing users to select the specifications that suit one's workpiece size. The specifications also allow up to a 9.4" diameter tool to be used, offering enhanced heavy-duty cutting ability.

The machine is also designed to be energy saving. Power supply for spindle motor, servo motors and fans inside the electrical cabinet can be stopped during shutdown mode, thereby contributing to reduction in environmental burden and running costs. The total electrical power capacity is also reduced, compared with conventional machines, and can achieve up to 30 percent of total electrical power savings.

The NVX Series uses the MAPPS IV high-performance operating system for its operation panel. In addition to automatic programming software, ESPRIT CAM software is available as an option. The combination of MAPPS IV and ESPRIT allows the machine to handle complex machining programming and to flexibly meet customer needs. Also, MAPPSIV is equipped with MORI-NET, which enables remote maintenance of the machine and confirmation of operation status.

Related Glossary Terms

  • centers


    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • computer-aided manufacturing ( CAM)

    computer-aided manufacturing ( CAM)

    Use of computers to control machining and manufacturing processes.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
