High Rigidity, Thermal Displacement Stability

The main benefits of the No. 50 taper spindle specifications for the NVX5000 Series includes high precision, high rigidity, expansion of machining variation, energy saving, a high-performance operating system, and high investment value.The NVX5000 Series of high-precision vertical machining centers are available with a No. 50 taper spindle variation.

The NVX5000 Series provides options and applications equivalent to those of the NV5000 Series, while achieving high levels of rigidity, thermal displacement stability, and energy saving. In addition to the No. 40 taper spindle specifications previously offered, Mori Seiki has expanded 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 doubles due to suppression of thermal displacement to less than half while improving the responsiveness of minimal feed. The accuracy of micro-fabrication has further improved by 100%, as micro-fabrication requires high accuracy, even on high rigidity machines with No. 50 taper spindles.

The combination of MAPPS IV and ESPRIT allows the machine to handle complex machining programming while flexibly meeting customer needs. In addition, MAPPSIV is equipped with MORI-NET, which enables remote maintenance of the machine and confirmation of operation status.
The NVX5000 Series provides 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 30/22kW (25%ED/cont.). The machine's overall high rigidity and high output/high rigidity of the spindle have additionally improved heavy cutting ability by 30%.

The X-axis stroke is available in three variations (23.6", 31.5", 41.3"), allowing users to select the specifications that suit their specific workpiece size. The specifications also allowed the use of up to a 9.4" diameter tool, offering enhanced heavy-duty cutting ability.

Designed to save energy, the machine's power supply for the spindle motor, servomotors, and fans inside the electrical cabinet are stoppable 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% 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 while flexibly meeting customer needs. In addition, MAPPSIV is equipped with MORI-NET, which enables remote maintenance of the machine and confirmation of operation status.
