Jan 07, 2016 Chicago, Illinois – As has become tradition, the focus of the DMG MORI Open House event at DECKEL MAHO Pfronten, Germany, January 26-30, 2016, will be on the latest innovations and groundbreaking technologies. In an exhibition space of 79,653ft², the machine tool manufacturer will be. Apr 03, 2014 The primary objective of the five-day open house is to bring customers, prospective users of DMG Mori equipment and journalists up to speed with technological developments, trends and new products. Of the 66 exhibits showcased in Pfronten this year, eight machines were world premieres – with a further 16 planned for launch later in the year.

DMG Mori is the combined sales and service operation for the currently separate firms of DMG Mori Seiki Co, Japan (formerly Mori Seiki Co) and DMG Mori Seiki AG, Germany (formerly Gildemeister AG), reports Andrew Allcock, Editor of Machinery UK. The two companies have been working together across sales, service, development, production, purchasing and finance since March 2009. There is already a cross-shareholding between the two, but they will become a single company in 2020, as announced in October last year.
With the Lasertec 65 Additive Manufacturing, DMG MORI presents a machine, which is currently unique and incorporates laser deposition welding into a fully-fledged 5-axis milling machine
Combined sales for the two global machine tool makers are over £2.5 billion (DMG Mori Seiki AG, €2 billion/£1.645 billion [to 31/12/2012]; DMG Mori Seiki Co, ¥150 billion/£884 million [to 31/3/2013]), while their combined production capacity is put at 20 000 machines a year.
World standing
So, by volume, that puts the couple ahead of Haas Automation, which claims the position of the largest producer of CNC machine tools in the Western world; and by value puts them ahead of Japan’s Yamazaki Mazak, which claims the position of “the world’s largest producer of CNC metalcutting machine tools”, (sales over €1.5 billion/£1.23 billion).
The DMG Mori Seiki AG turnover figure includes its energy products activity, so its machine tools’ revenue is lower than the headline figure, at €1.175 billion/£966 million but services related to machine tools are put at €790.5 million/£650 million, so, on combining these figures, the Yamazaki Mazak claim could be challenged, although DMG Mori Seiki AG makes no such challenge. Overall employee count for DMG Mori Seiki AG and DMG Mori Seiki Co is 10 400, with DMG Mori boasting 500 employees.
Generative manufacturing
The unmistakable overall message is that the two companies together are a major global force in the machine tool industry. Across the world, there are almost 500 DMG Mori machine tools in some 100 DMG Mori showrooms, staffed by the 500 employees, while there are also 50 technology partners.
The two companies have a combined product offering of around 200 machine models, although rationalisation to around 100 models is on the cards, with these machines produced at 19 machine tool manufacturing sites worldwide.
And with an R&D workforce approaching 1 000 engineers, the frequent announcement of new products is a habit that only gathers pace, with the February Pfronten, Bavaria, Germany Open House a major fixture on the calendar. Eight world premières were unveiled to an audience of 6,000+ visitors. And they “come to learn what’s new from DMG Mori, what innovations we have to offer”, says Mori Seiki AG chairman of the board Dr Ruediger Kapitza.
Sauer Lasertec 65 Additive Manufacturing
The technological highlight this year was the Sauer Lasertec 65 Additive Manufacturing, a machine that combines traditional milling/toolchanging with additive manufacturing in the frame of a DMU 65 monoBLOCK machining centre. A development from DMG Mori Seiki AG company Sauer AG, the machine offers a unique proposition – the ability to create solids from powder and then machine them to the finished state.
First revealed at Euromold last December, the Lasertec 65 incorporates a 2 kW diode laser system (glass fibre optic-transported beam), located to the right in the working envelope. Build rate, at 3.5 kg/hour, is 20x faster than for powder bed machines. Wall thicknesses of 0.1 mm to 5 mm can be built up, depending on the laser and the nozzle geometry, while complex 3D contours can also be generated in layers, without the need for supports. The machine’s capacity is 650 mm diameter by 360 mm in height, with a maximum weight of 1,000 kg.

The use of a powder nozzle additive manufacturing system allows for a faster material build-up versus powder bed machines (which cannot machine), while such technology is “easily implemented within a machine tool”, according to Friedmann Lell, Sauer GmbH sales director. Indeed, the technology could be incorporated into any number of DMG Mori machine tools.
At the Pfronten Open House, a funnel-shaped part was shown being produced, via video. Approximately 150 mm high and 180 mm diameter at its widest end, it features annular spigots around the funnel’s external wall and also has two flanged ends featuring drilled holes. Built from nothing using stainless steel powder and then fully machined, it takes some about five hours. The same part would take around 50 hours, using a powder bed machine, would need support structures added during build and, of course, would not be finished machined.
The machine on show at Pfronten was a ‘project’ – a functional study – not the finished machine. Currently only dry machining is possible, as the laser is not fully protected, but the final design will support coolant use, with full protection for the laser. That machine will be available around the middle of the year and will break cover at the IMTS 2014 (Chicago, USA) and then AMB (Stuttgart, Germany) exhibitions. And Mr Lell says that five machines will be shipped this year. Unsurprisingly, the machine price is not yet fixed.

While a machine such as this could have been developed some years back, the reason for its development now is customer demand. There is no additive machine currently available that offers the surface quality and component accuracy that DMG cutting machines do: “So we developed an additive manufacturing machine for our customers that does give such quality and accuracy.” And there is “unbelievable interest”, with this emanating from Europe and the USA, Mr Lell offers.
Regarding the temperature of the additively produced features, if highest machined accuracy is required, then cooling must take place prior to cutting – the application of coolant to accelerate that process is a possibility, he says.
As for material properties, currently stainless steel is the trial material. “We are not finding any porosity,” Mr Lell says, but adds that the company “is not yet the process expert”.
Inconel and aluminium
The next material to be tested will be Inconel, which has long been used in additive manufacturing, so should present little problem, he suggests. Following that, aluminium is the next material on the agenda, but this does present greater challenges regarding porosity, so will require greater process development.
For the project machine, CNC programs are being generated via two systems: one for the additive element of the process and another for the cutting element. At the launch of the production unit this year, there will be a single software system for programming, Mr Lell says, with the machine itself using Siemens CNC only.
Coating
As to the matter of process control/repeatability and consistency of component quality/performance, this will require further machine development. At the moment there is no process control. “For aerospace turbine or aircraft parts, if you make 1 000 parts, how do you avoid any failures? This is an open question. There will be process monitoring in the future, with many parameters involved. But there are many parts today that do not require this level of control,” Sauer’s sales director explains. It’s the same situation for powder bed machines, of course, although there are efforts in this area under way already.

And the market for its Lasertec 65 Additive Manufacturing? Well, around 100 metal AM powder bed machines are sold annually. This is the first time a machine dedicated to manufacturing has been developed, so it’s a new market. Its launch will “definitely give a push to the market” with its potential “tremendous”, Mr Lell concludes.
