Irving, Texas, January 31, 2006 – Mori Seiki recently unveiled the NVD1500 DCG^®, a high precision vertical machining center designed specifically for those in the die and mold and precision parts industries. Traditionally, smaller machines have been associated with increased vibration, causing small, high precision parts to require larger machines than would otherwise be necessary. With an efficient, compact design, the new machine offers an overall size appropriately matched to its workpiece. The new machine packs a variety of cutting edge technologies into a machine with a footprint of just 33.5" wide by 76.2" deep. The X and Y-axis travels are 5.9" and the Z-axis travel is 7.9".

With DCG (Driven at the Center of Gravity) technology, the net driving force acts through the center of the axis. The NVD1500 DCG contains five ballscrews - two on the Y-axis, two on the Z-axis, and one on the X-axis - that enable a significant reduction in vibration without sacrificing speed for accuracy. Unlike machines using dual ballscrews in all three axes, which can reduce the overall dynamic response of the machine, the new N Series machines only incorporate twin ballscrews when it provides benefit.

To further provide high levels of precision and accuracy, the NVD1500 DCG’s design reduces the effects heat typically has within the machine. The oil cooler and electrical cabinet are isolated at the rear of the machine, minimizing the transfer of heat and vibration to the critical machine components. Coolant passes through the Z-axis servo motor bases to eliminate thermal displacement caused by heat transferring from the servo motors to the ballscrews.

Additionally, the absolute positioning optical scale allows for unequaled positioning, to a .05 µm resolution. The lead of the ballscrews is 0.2 in., raising feed rigidity during operation. The Z-axis drop prevention automatically backs the tool tip away from the part in the event of interruption to the machining cycle.

The NVD1500 DCG includes a standard spindle capable of a max speed of 24,000 rpm, with an available option of 40,000 rpm. The standard 30-tool ATC features a chip-to-chip time of just 3.7 seconds.

The NVD1500 DCG integrates Mori Seiki’s industry leading MAPPS II control system and the operating panel swivel 180°, saving space and ensuring easy access. A variety of options for lights out operation are available, including a compact AWC (Automatic Workpiece Changer) capable of housing 24 workpieces.
