No 50 taper spindle for Mori Seiki NVX5000

Mori Seiki has started taking orders for No 50 taper spindle specifications for the NVX5000 series of high precision vertical machining centres.

The Mori Seiki NVX5000 employs a technology that circulates coolant inside castings of a bed and column (option) as well as a spindle using a heat-symmetrical structure that minimises thermal displacement. This enables the machine to achieve thermal displacement of 7 micrometres or less in response to an 8°C change in ambient temperature. Thermal displacement has been suppressed to less than half and responsiveness of minimal feed has been improved. This has improved the accuracy of micro-fabrication by 100% and allows machining of various materials and workpieces under the ideal machining conditions, says Mori Seiki. The NVX5000 series uses slideways on all axes for increased machine rigidity. No 50 taper spindle specifications include a high output motor with 30/22 kW. The machine has achieved high rigidity by making spindle bearing inner diameter larger up to f120 mm, which is the largest in its class. High rigidity of the machine and high output/high rigidity of the spindle have improved heavy cutting ability by 30%. There are 600, 800, and 1,050 mm X-axis stroke options available, allowing users to select the specification that best suits their business needs. The specifications also allow up to a 240 mm diameter tool to be used, offering enhanced heavy duty cutting ability. Power supply for a spindle motor, servo motors and a fan inside the electrical cabinet can be stopped during shutdown mode. The total electrical power capacity is also lower than conventional machines, says Mori Seiki. The NH 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. MAPPS IV is equipped with Mori-Net for remote maintenance of the machine and confirmation of machine status.
