Made in the USA
DMG Mori’s North American manufacturing plant in Davis, Calif. opened in July 2012. It has a production capacity of up to 100 machines per month, and DMG Mori domestically manufactures and assembles the two of its world-premieres there, the NHX 4000 2nd & NHX 5000 2nd Generation. It also produces the NHX 6300 and the DuraVertical 5100 and DMU 50 machines.
The 200,000 sq.ft. factory was built adjacent to DMG Mori’s design center and Digital Technology Laboratory (DTL), which Mori Seiki developed 14 years ago to research machine tool designs, controls and pallet systems.
CELOS Control Platform
In addition to DMG Mori’s product innovations, its development work focuses on optimization of customer processes. In this context, the premiere of CELOS last year marked a turning point due to the fact that it simplifies and accelerates machine processes, from concept to the finished product, and forms the basis of paperless manufacturing.
“CELOS is as easy and intuitive to use as a smartphone, compatible with PPS and ERP systems, suitable for networking with CAD/CAM applications, and ready for future CELOS APP extensions,” DMG Mori claims.
World premiere 1: NHX 4000 2nd Generation
Two of the three machines that will have world premieres at IMTS are manufactured at Davis: the NHX 4000 2nd Generation and NHX 5000 2nd Generation horizontal machining centers.
DMG Mori’s NHX series high-precision, high-speed horizontal machining centers offers high-speed, high-rigidity and high-precision machining.
The new NHX 4000 and NHX 5000 heavy-duty horizontal machining centers are said to be “ideal” for machining workpieces of up to 31.4 x 39.3 in., with a loading capacity of up to 1,100 lbs (NHX 5000 2nd Generation, optionally up to 1,540 lbs).
Now, the machines are now equipped with an even more powerful spindle, offering 15,000 rpm and an excellent power-to-torque ratio of 29.5 hp. with 93.7 ft/lbs. Rapid traverse has been increased to 39.4 in/s or 63.0 in/s (optional), while the new design and the advanced controller (MAPPS V and CELOS) complement the machine’s high-performance features.
World premiere 2: NHX 5000 2nd Generation
The workpiece range of the NHX 4000 with 400-size pallets (15.7 x 15.7 in.) comprises workpieces up to 24.8 in. in diameter and 35.4 in. in height (NHX 5000 2nd Generation: 31.5 x 39.4 in.). In a work area of 22.0 x 22.0 x 26.0 in. (X/Y/Z) for the NHX 4000 and 28.7 x 28.7 x 34.6 in. (X/Y/Z) for the NHX 5000, the horizontal centers machine components extremely accurately and efficiently.
Chip-to-chip time has been improved to less than 2.4 seconds.
The demands for precision on the NHX series, which is also reflected in a circular accuracy of < 0.000067 in. with 1.3 in/s feed in X and Y as well as 3.9 in. radius, go hand-in-hand with impressive speed and dynamic values, according to DMG Mori.
Additive Manufacturing / Finished-Part Quality
Additive manufacturing offers new possibilities for complexity and individuality in product design, and the market for additive technologies is rapidly growing. DMG Mori’s hybrid technology combines subtractive machining (SM) and laser metal deposition processes for additive manufacturing (AM).
The LASERTEC 65 3D is based on a DMU 65 monoBLOCK® machine and was developed by Sauer Lasertec in Pfronten, Germany, in collaboration with DMG Mori USA. The machine is equipped with a diode laser for metal deposition, while the 5-axis machine platform allows accurate SM operations.
The metal deposition process via powder nozzle is up to 10x times faster than laser sintering in a powder bed. All common metal powders can be processed, including steel, nickel and cobalt alloys, brass or titanium. Wear protection layers can also be applied on the base material.
