3D/Additive/Alternative Machining Centers

In booth #338900 at IMTS 2018 DMG MORI points the way to the future of the digital factory with numerous software and data-based products and services, showcases three U.S. premieres that have expanded the company’s portfolio and diversified its machining center options in North America, and highlights automation solutions such as robotic and linear pallet pool systems.

Additive manufacturing (AM)
DMG MORI has already been operating successfully in the market for AM since 2013 with directed energy deposition using powder nozzle technology. With its deposition-to-finishing competence, DMG MORI presents the most important additive manufacturing machining processes under one roof and ranks as a full-solution provider in both the additive production of metallic components and metal cutting. The highlight that will be featured at IMTS this year is the Lasertec 30 SLM.

With the powder bed technique, very small, highly complex parts can be manufactured by means of selective laser melting. The Lasertec 30 SLM enables the flexible use of different materials, while an intelligent powder module concept allows the change of material in under two hours. The closed powder circuit also guarantees a high degree of work safety and process autonomy. The ergonomic design of the machine simplifies workpiece handling and maintenance work through the arrangement of doors and flaps, while the new stealth design control panel keeps important buttons and operating elements in direct view and control panel.

The Lasertec 30 SLM enables holistic software solutions to realize workpieces of various materials with high density and very good mechanical behaviors. This selective laser melting machine produces 3D parts with lattice and honeycomb structures which are not achievable with other machining methods. It has an integrated powder recycling center for even more efficiency and improved powder handling in removable units for better reliability.

Integrated digitization
DMG MORI has further developed its CELOS control and user interface to create an open and consistent ecosystem for digital production. In the current CELOS version, the focus is on digital workflows for adaptive production planning and integrated tool management. DMG MORI’s current digitization initiatives are based on the vision of the digital factory, which is characterized by adaptive factory structures. The digital factory’s key feature is the automatic, data-based adaptation of processes in production to changing framework conditions.

The major focus of the CELOS Ecosystem is its open connectivity which enables CELOS network integration with machines from other manufacturers, machines in complementary technological areas and manual workstations. Even older machines have to be connected to a certain degree.

Three US premieres
DMG MORI will be premiering for the first time in the U.S. two XXL machines: the DMU 200 gantry and DMU 340 gantry. The machines of the gantry series have been specifically developed for highly dynamic universal applications of large components. Both models offer 5-axis simultaneous machining on the largest work area with the smallest space requirement.

The DMU 200 gantry impressively combines the machining of large components and maximum dynamics and improves user benefits in the aerospace and automotive industry as well as in mold-making and the energy sector. With the 5-axis machining of up to 30,000rpm and optional ULTRASONIC or LASERTEC technology integration, more complex components weighing up to 22,046 lb made of aluminium or composites as well as welded components can be machined economically.

The DMU 340 gantry impresses with its top gantry design that makes this machining center powerful, dynamic and universally applicable. This new machining center is the impressive result of an in-depth liaison with the large component manufacturers from the aerospace industry, general mechanical engineering as well as tool and mold manufacturing. The work area of the DMU 340 gantry measures 134" x 110" x 49" and provides expansion options to up to 236" in the X- and 59" in the Z-axis. Due to its gantry design, it also has compact dimensions.

Modern equipment options, compact dimensions and a high level of automation are all decisive for the efficiency of a turning machine. DMG MORI has taken this into account in the development of the new ALX 2500, so customers from the automotive and other demanding branches such as general mechanical engineering have a model available that meets the high demands of serial production. On barely 52.6ft², the stable, dynamic turning machine offers perfect ergonomic design for operation and maintenance by uniting excellent standards from a max. spindle speed of 3,500min-1 to the BMT turret with 12 powered tools and tailstock. In addition, the ALX 2500 provides a high degree of automation thanks to the optional gantry loader, a factor decisive for cost effectiveness in production.

Made in USA
DMG MORI’s North American manufacturing facility, located in Davis, California, is dedicated to offering customers comprehensive local engineering and support for the highest quality of U.S. made machine tools. Design and production activities in California offer customers the world’s best CNC hardware with price-competitive, customized technical solutions to today’s most demanding production challenges.
