Berthiez Bumotec Dörries Droop + Rein Heckert Scharmann SIP Starrag TTL WMW Machines / Service / Software Machine programme

The companies in the Starrag Group develop and supply machining centres and flexible production systems for milling, drilling, turning and grinding medium and large-sized work pieces. We provide innovative technology solutions which are tailored to the requirements of our customers, to enable: ► sustainable reductions in unit costs ► long-term, consistent precision in the size and geometry of complex work pieces ► shorter cycle times ► increased long-term precision Leading companies around the world choose Starrag Group products since they know that comprehensive technology solutions are...

Aerospace: Lighter, quieter, more economical. The leading constructors and suppliers in the aerospace industry work together with the companies in the Starrag Group, be it for landing gear, structural components, stringers or turbine elements such as blades, blisks and casings. Aeroplanes are increasing in size, and with rising energy prices and a growing sense of environmental responsibility acting as catalysts, they are also becoming lighter, quieter and more economical. Aircrafts are changing, and with the increasing implementation of CFRP parts, more and more titanium is being used...

Transport: Perfection, security and productivity. The core competency of the Starrag Group is based on efficient production solutions, which enable unit costs to be reduced and lead to sustainable success. The most important decision-making criteria from a customer point of view when it comes to investments in new production solutions are: minimum production and down times, reduced energy consumption, a high number of work pieces in the working space, high levels of retooling flexibility, maximum availability and the overall investment costs. The competitive strength of automobile...

Industrial: Increasingly complex work pieces, optimised components. Demand is rapidly increasing around the markets for flexible machining concepts. This development is directly related to the clear trend towards work pieces of ever-increasing complexity and optimised machine components such as racks, casings and transmission components for machine tools, injection moulding, printing machines, etc. That the Starrag Group machining centres are able to meet these demands is down to the fact that the technologies used are truly universal: the centres can fully machine a work piece on five...

Energy: First in line and fully committed. Energy requirements are growing, as is the realisation that our stocks of oil and gas are finite. It is thus becoming ever more important to use existing resources well, whilst at the same time looking into all the possibilities of alternative energy sources. Energy recovery facilities are now hi-tech installations, and parts manufactured on our machines need to meet higher demands – they have to be bigger, more complex and increasingly made from materials that are difficult to machine. Turbine blades for gas and steam turbines, large ball cut-off...

The TVU product range from Berthiez offers vertical turning machines which are particularly suited to the machining of drive unit and turbine components. They are used in a wide variety of industrial sectors such as the aerospace industry and all types of energy production, from wind to nuclear power through to oil power. The TVU range is the fruit of Berthiez's experience and development programme over the years, combining the latest findings with a comprehensive technology offer. –– Berthiez TVU Advantages of TVU vertical turning lathes are completely cast iron construction, high static...

The RVU generation of grinding machines sets new standards in terms of highprecision machining and is your guarantee of sustainable competitiveness. These grinding machines are ideal for high-precision mechanical machining, for example for the precision friction bearings and the aerospace industries. The range can be fitted with up to four water-cooled grinding spindles which can achieve a performance of 45 kW at 18,000 rpm (depending on which grinding machine is used). –– Berthiez RVU The design of the machines enables the complete machining process to be carried out without interruption,...

The Dörries Contumat VCE is a compact single column vertical turning machine with a swing diameter of 1,400 – 2,800 mm. Depending on requirements, the machine can also carry out drilling, milling and grinding work as well as its main task of turning. The additional units required for this are of course made available, enabling customers to carry out extensive complete machining of work pieces. The eccentric design with its stiff cast set-up combined with the damping characteristics of the hydrostatic guideways provides a low-vibration machine configuration. The technical design of the...

The Dörries Contumat VC range in either the double-column or portal design is ideal for larger swing diameters of 3,500 – 12,000 mm. The VC range combines all the advantages of the VCE range with the ability to machine large-scale components just as effectively. The positive constructive properties of the smaller range are taken over here in correspondingly dimensioned main components. The range also provides high levels of flexibility in combining modules, with the result that the customers are able to find a solution tailored to their needs. –– Dörries CONTUMAT VC The portal design of the...

The Dörries Contumat VC-V range provides the utmost in flexibility when it comes to work piece machining. As is the case with all the ranges mentioned previously, it is suitable for all machining processes, namely turning, drilling, milling and grinding. Furthermore, the moveable table (with a third linear or y-axis) enables eccentric work piece machining combined with the correspondingly actuated tools and thus complete machining of complex work pieces. –– Dörries CONTUMAT VC-V Machining at any position of the work piece is possible on machines with a y-axis, with the machine stand located...
