Mori Seiki will be unveiling several new groundbreaking machines at IMTS, including the NT5400 DCG™/1800S. This new mill-turn machine features a sub-spindle, allowing for high-speed and high-precision continuous machining.

Chicago, Illinois, September 6, 2006 – Mori Seiki’s new NT Series of integrated mill-turn centers fully combines a lathe with a machining center. In designing the series, Mori Seiki completely rethought the design and construction of multitasking machines to harness the turning ability of a lathe and the cutting ability of a machining center.

The NT5400 DCG/1800S employs both DCG™ (Driven at the Center of Gravity) technology and the box-in-box construction of the NH Series horizontal machining centers, along with the turret with a built-in milling motor from the NL Series CNC lathes. The combination of these features is included with no compromises in terms of their performance.

The NT5400 DCG/1800S features a sub-spindle, allowing for high-speed and high-precision continuous machining. The machine’s maximum turning length is 70.8". The mill-turn center is in the 15" chuck size class and commands a maximum bar work diameter of 4.1".

Like all machines in the NT Series, the NT5400 DCG/1800S contains a B-axis that uses a DD (Direct Drive) motor, eliminating backlash and making high-speed rotation possible. Indexing specifications for the axis cater to high precision machining requirements, allowing for input by units of 0.0001 degrees.

To make the NT Series as efficient and productive as possible, special attention has been paid to machine speed. The NT5400 DCG/1800S’s maximum tool spindle speed is 8,000 min-1 with a maximum spindle speed of 2,400 min-1. Additionally, the machine’s ATC (Automatic Tool Changer) features a tool-to-tool change time of just 1 second. This model features a tool magazine that stores a standard number of 20 tools, in addition to a 40-tool and 60-tool option, for a total of up to 100 tools.

Special attention to thermal displacement allows machines in the NT Series to perform at the highest levels of accuracy and precision. The lower turret is located symmetrically in relation to the center of the spindle, forming a construction resistant to the effects of heat. Additionally, ball screw and motor jacket cooling have been implemented to completely eradicate inaccuracy caused by heat variations.

The NT5400 DCG/1800S will make use of MAPPS III, the latest iteration of Mori Seiki’s highly successful control system. MAPPS III allows fast processing and is equipped with a collision prevention function that monitors machine movements in real time. The controls also take advantage of the ease and convenience of conversational input, providing high-speed canned cycles that lead to dramatic increases in programming speed.

Mori Seiki produces extremely reliable machine tools and distributes worldwide. The U.S. headquarters is in Chicago with offices in Boston, Chicago, Cincinnati, Dallas, Detroit, Los Angeles, and New Jersey.
