Download scientific diagram Laser engraving machine DMG MORI Lasertec 40 (a) Exterior view and (b) interior view. DMG MORI has performed successfully on the market since 2013 with the combination of laser deposition welding and metal-cutting machining on the machines of the LASERTEC DED. Laser Additive Manufacturing Machine Using Powder Bed.This was the technology highlight this year at the company’s Open House exhibition held in February in Germany, while further global expansion plans were revealed.For this integral offer DMG MORI combines its LASERTEC SLM models and the LASERTEC DED series with the machining centres from its broadly diversified machine portfolio. ULTRASONIC / LASERTEC 3 UP.Fast Scan Mode for similar texturing quality also at high scanning speeds. Fibre laser with 100 W (1.000 kHz) and new, compact laser head design for +7,44 in. There is already a cross-shareholding between the two, but they will become a single company in 2020, as announced in October last year.New improved machine concept. The two companies have been working together across sales, service, development, production, purchasing and finance since March 2009.Eight world premières were unveiled to an audience of 6,000+ visitors. 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. Overall employee count for DMG Mori Seiki AG and DMG Mori Seiki Co is 10 400, with DMG Mori boasting 500 employees.The unmistakable overall message is that the two companies together are a major global force in the machine tool industry. Since the end of 2014, Hoedtke has been using a Lasertec 65 3D laser deposition welding and milling machine from DMG MORI, equipped with a Siemens Sinumerik.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 machineCombined sales for the two global machine tool makers are over £2.5 billion (DMG Mori Seiki AG, €2 billion/£1.645 billion DMG Mori Seiki Co, ¥150 billion/£884 million ), while their combined production capacity is put at 20 000 machines a year.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.The machine’s capacity is 650 mm diameter by 360 mm in height, with a maximum weight of 1,000 kg.The laser head features an HSK back end, with the spindle picking it up from its location, which is currently within the working envelope. 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. Build rate, at 3.5 kg/hour, is 20x faster than for powder bed machines. 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.
![]() Dmg Laser Hine Series With TheBuilt from nothing using stainless steel powder and then fully machined, it takes some about five hours. 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. 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. The 5th wave download torrentUnsurprisingly, 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. And Mr Lell says that five machines will be shipped this year. 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. 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. At the moment there is no process control. 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.As to the matter of process control/repeatability and consistency of component quality/performance, this will require further machine development. 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. “We are not finding any porosity,” Mr Lell says, but adds that the company “is not yet the process expert”.The next material to be tested will be Inconel, which has long been used in additive manufacturing, so should present little problem, he suggests. ![]()
