MORI SEIKI｜NEWS

As the economy continues to feel the recession, manufacturers are pinning productivity hopes on cost reductions through raised efficiency. At Mori Seiki, we recognized those needs early on and in November 2000 began development of a next-generation vertical machining center designed specifically to raise customer profits.

When development began, we incorporated a variety of new technologies while pursuing convenience that would exceed that of conventional machining centers. To begin with, we drastically raised the acceleration and deceleration speeds for the spindle and feed, while at the same time, we increasing the capacity-operating rate of the machine by raising ease of use and maintenance. Efforts in the area of digital design and MTTR (Mean Time To Repair), as well as IT^*1 and ecological considerations, allows us to bring out the best possible performance. We also implemented a thorough revision Fof running costs, tool, and machine lifespan, as these are important factors in raising profits.

And on March 15th and 16th the NV5000 was unveiled simultaneously throughout the country at product presentations held at the Iga Plant and technical centers. Alongside presentations on features, demonstrations were also performed to show actual comparisons of productivity. Demonstrations also were held at exhibitions at technical centers throughout the country using actual machines, so be sure to visit your nearest Mori Seiki technical center and see for yourself the outstanding performance of the NV5000.

Some of the main features of the NV5000 are:

1.Basic Design
  By using 3-D CAD modeling and repeated testing with FEM^*2 analysis, solid strength has been ensured through use of digital design for the basic design. The current design is a result of evaluations of two types of double housing prototypes built specifically for this purpose. The size of the machine is the smallest in its class.

2.High-Speed Mechanism
  With the goal of reducing non-cutting time, acceleration and deceleration times have been dramatically reduce over conventional machining centers for the spindle and rapid feed at all axes. This has further allowed excellent high-speed synchronized tapping, synchronizing the spindle revolution speed and the Z-axis feed rate. In comparison trials with the previous SV-503, the NV5000 achieves 1.5 times greater speed for tapping holes of the same size and depth.

3.High-precision
  Of all vertical machining centers in existence, our products have always had a reputation for high accuracy. We have contributed to stable supply of high-quality workpiece by making it possible to equip machines with a thermal growth compensation function.

4.Improved Convenience
  The operation environment, including the width the door opens to and the approach to the machine, has been designed by applying our long years of experience and listening to our customers' suggestions. The internal and external chip conveyors on the NV5000 have been integrated into one unit. This minimizes chip disposal and maintenance hassle.

5.Eco- friendly design
  We have incorporated a wide range of new technologies that reduce the environmental burden-one of the biggest concerns facing the industry today. For example, we have used a mechanism to reduce lubricant consumption with oil-free roller guides and an oil-bath ATC.

6.MTTR (Mean Time To Repair)
  The NV5000 has been designed to reduce MTTR, an indicator of overall maintainability and is important when raising productivity. Eliminating disposable parts and redesigning the layout of the various components that make up the machine allows efficient performance of maintenance and tuning.

Until now, Mori Seiki has produced a large number of machining centers and CNC lathes, but with the NV5000, we have concentrated all our own expertise and comments from suggestions into one machine, making this a truly multipurpose machine.
This machine symbolizes a new direction for Mori Seiki development and manufacture, so we are confident it will live up to your expectations.
