Mori Seiki has started taking orders for the NHX10000 high‐precision horizontal machining center. This machine is the latest and largest model in the NHX Series of X‐class horizontal machining centers. With a maximum workpiece size of 78.75 in. x 63 in. and a maximum loading capacity of 11,023 lbs, the NHX10000 is suitable for machining large workpieces and difficult‐to‐cut materials, which are in great demand in the aircraft, construction machinery and energy industries. Key features of the NHX10000 include: original technologies for high‐speed and high‐precision, reliability, single pallet specifications, extensive options, MAPPS IV + ESPRIT and compliance with safety standards.

Inheriting the structural concept of previous NH Series models, the NHX10000 employs the Box‐in‐Box Construction that supports the saddle at both sides. The symmetrical structure with respect to the spindle minimizes thermal displacement. Additionally, Mori Seiki's DCG (Driven at the Center of Gravity) technology is used for the X‐ and Z‐axis drive. DCG controls vibration, the main factor preventing high‐speed, high‐precision machining, by driving moving parts at their center of gravity using two ball screws. As a result, machining accuracy is improved, machining time is reduced and tool life is extended.

The NHX10000 has achieved roundness of 2.1 μm (when equipped with a scale), as well as a rapid traverse rate that is 2.5 times faster (50 m/min.) than the previous model. The excellent vibration control also contributes to improved surface quality. For the B‐axis drive, a full indexing table equipped with DDM (Direct Drive Motor) is available as an option. By transmitting the drive power directly to the rotary axis, DDM eliminates backlash and provides outstanding transmission efficiency and high‐speed feed. The 90‐degree indexing time for a workpiece weighing 11,000 lb is shortened to 2.0 seconds, one‐fifth the speed of the previous machine. For heavy use of high‐pressure coolant, the NHX10000 spindle has an advanced labyrinth structure in which coolant hardly enters the spindle unit. An optional universal chip conveyor is also available. The height difference between inside and outside of the machine has been eliminated by installing work platforms. With a wide door opening (191.6 ft.) for the setup station, the machine allows easy loading and unloading of workpieces up to 78.75 in. in diameter.Additionally, the machine is equipped with three spiral conveyors to offer excellent chip disposal. These conveyors, two of which extend to the setup station, collect chips from the setup station and transfer them to the external conveyor. In response to many requests from customers, single pallet specifications are available for the NHX10000. The machine's simple and space saving design was made possible by the elimination of the two‐pallet turn‐type APC.

The machine with a single pallet offers a large working area, which facilitates setups. The single pallet specifications are best suited for machining one‐off parts, such as prototype workpieces. The optional long‐tool magazine is capable of storing tools up to 39.37 in., the same size as the pallet. The use of long tools enables deep hole boring and gun drilling of large workpieces that require highly accurate coaxiality without a 180‐degree turn on the B‐axis, achieving reduced cutting time and high‐precision machining. For customers who require further high‐precision machining, the high‐precision, multi‐path oil controller is available as an option. Ideal control for thermal displacement is achieved by separately circulating the optimum temperature cooling oil in the multiple heat‐generating components.

The NHX10000 uses the MAPPS IV high‐performance operating system for its operation panel. Because a license for ESPRIT CAM software is provided in addition to the automatic conversational programming function, the machine allows users to create highly complex machining programs on a PC connected to a networked machine.
