DMG MORI Expands Technology Workforce, Product Lineup

Executives from DMG MORI showed off new technologies, along with 33 running machine tools, to nearly 2,000 visitors at its annual Innovation Days event outside Chicago, where Dr. Masahiko Mori, President of DMG MORI Co., Ltd. outlined his view of the global machine tool market.
Dr. Mori and Dr. Thorsten Schmidt, CEO of DMG MORI USA, have been in the process of creating a direct sales model in the United States, doubling the company’s existing service and sales centers to 27 locations and 1 manufacturing plant, including 5 dealer technology centers, to better serve changing needs.
During the event, which was held May 17-20, Dr. Mori said the company has expanded rapidly, hiring more than 750 employees nationwide. Of those, 250 are application and service engineers.
Dr. Mori said he would like to further grow the number of applications engineers to about 150 from 82. He would ultimately like application engineers dedicated to each region, delivering a more localized approach to sales, application support and service.
During the show, DMG MORI showed off 33 machines running live demonstrations, including two US premiers previously shown at EMO in Milan:
• SPRINT 32 | 5 – Highly productive SWISSTYPE machine. Along with the SPRINT 32 | 8, these new machine tools expand DMG MORI’s series of automatic lathes for bar material with diameters of up to 1.26 in. With a footprint of just 30.1 ft2, the two new models are the most compact in their class while offering a large work area for workpieces of up to a diameter of 1.3 in. x 23.6 in. The Sprint 32 | 5 comes with 5 linear axes and a C-axis on the main spindle and has 2 independent tool carrier with space for up to 22 tools. There are 4 pockets available for powered tools for radial machining on the main spindle.
• CTX gamma 2000 TC 2nd Generation – The Turn-Mill machine for 6 sided complete machining. The machine comes with the new milling spindle compactMASTER II. With a length of 17.7” the spindle offers up to 162 ft*lbs torque at 12,000 rpm. The torque performance has been improved 120% compared to the 1st Generation while the length has been reduced by 2.8”. With 31.5” X- (plus 30%) and 16.5” Y-axis travel (plus 5%) the utilization of the working area has been optimized. The chain magazine can now accommodate tools up to 21.7” length (plus 30%).
Dr. Mori spoke with great pride about the company’s lineup and new models.
In a press conference, Dr. Mori also noted that the company planned to roll out an Industrial Internet of Things factory at its Davis, California, factory, and he and Dr. Schmidt spoke at length about the company’s commitment to workforce development and its apprentice program.
Schmidt said the company is grooming potential employees with the idea “they will stay with us for 40 years.”
DMG MORI’s wholly owned subsidiary, Sauer GmbH, which was acquired in 2001 and whose technology underpins DMG MORI’s Lasertec line, also showed off an array of newer ultrasonic technologies outfitted on DMG MORI machines. That included the ULTRASONIC 30 linear and the ULTRASONIC 65 FD monoBLOCK.
Benedikt Brocks, Sales Director for the Ultrasonic line at Sauer, told Manufacturing Engineering that ultrasonic assisted machining of superhard and challenging materials, such as titanium, Inconel, composites and ceramics, is advancing quickly.
While ultrasonic cutting knives have been used to cut composites in aerospace and other sectors for some time, Sauer is using ultrasonic technology to assist with grinding and milling and it now offers a spindle head equipped with ultrasonic technology that turns a 5-axis machine into an ultrasonic machining center. Using induction and Piezo-elements inside the oscillation motor, the technology can deliver 20-50 KHz of vibration with an amplitude up to 15µm.
For manufacturers who see several markets moving away from metals to lighter weight composites, Titanium, Inconel or Ceramics, this technology can offer flexibility, as well as other benefits. Using ultrasonic assist also allows for less force – as much as 30-40% less -- to be used in cutting, which can help improve tool life, deliver a finer cut and improve throughput. It can also reduce chip size.
“It’s just a tool change,” Brocks said. “We have a real good understanding of the hard and brittle materials,” he said.
