HMC offers highest linear axes acceleration

A high-speed, high-precision horizontal machining center, which applies 'Driven at the Center of Gravity' theory, has world's fastest acceleration and rapid traverse rate on all linear axes.

In June 2006, Mori Seiki started accepting orders for the successor to our best-selling NH5000 horizontal machining center, the NH5000 DCG high-speed, high-precision horizontal machining center, which applies DCG (Driven at the Center of Gravity) theory.

Now that our main product, the 500mm (19.7in) pallet class machine, has been reborn, the whole series will meet customers' needs for reductions in cutting time and high-precision machining, which can only be achieved by DCG machines.

This machine has a brand-new structure which achieves dramatically increased speed, superior surface quality and contouring accuracy and extended tool life.

Thanks to the adoption of DCG, it boasts the world's fastest acceleration and rapid traverse rate on all the linear axes, and reduces machining time by 30% compared with previous machines.

Cutting time has also been greatly reduced, because Mori Seiki's unique 'DD (Direct Drive) motor' technology, which achieves the industry's fastest indexing time, is used for the B-axis drive (option).

And while conventional machines required B-axis turnover during boring of long workpieces, because of the limits on the Z-axis travel and the maximum tool length, the NH5000 DCG can do boring without turning the table over by setting the maximum tool length the same size as the pallet <500mm (19.7in), offering boring with higher precision than previous models.

It offers superior performance for case machining which requires repeated B-axis indexing and hole drilling after surface machining, and for simultaneous 4-axis machining of impellers.

As an advanced version of the NH Series, the NH5000 DCG has evolved into a machine which is ideal for parts machining, with features such as reduced machining time, space savings and continuous operation in order to provide the greater productivity which is demanded today.

Mori Seiki will continue to strive to develop products which support customers' machining sites.
