Dorries Scharmann, part of the Swiss-based Starrag Group, offers its redeveloped ECOFORCE series and comprehensive ECOSPEED portfolio. "Our Scharmann brand provides innovative solutions in the field of horizontal machining centers," said Dr Norbert Hennes, Managing Director of Dorries Scharmann Technologie GmbH (DST), based in Monchengladbach, Germany.
The column in central design is one of the key features of the redeveloped ECOFORCE series, which includes an extensive range of core components developed and produced in-house. "These components allow the series to be adapted to virtually any machining task, and include main spindles, gears and tables, as well as a multitude of attachment heads that can be exchanged automatically," said a company spokesperson. "The facing head can also be exchanged automatically. It enables turning work to be carried out on the machine and has been given the seal of approval by even the most demanding of users. This option turns a machine from the ECOFORCE series into a multifunctional, all-around solution that allows users to drill, cut and turn materials in a single clamping process."
The redeveloped series can be used for full, five-sided or five-axis machining in a table or pallet design with its spindle box and moveable quill (W-axis). It can machine workpieces weighing 10,000 to 40,000 kg in a continuous process. The four table sizes (1,250 x 1,600 mm to 2,500 x 3,000 m) or eight potential pallet sizes (1,000 x 1,000 mm to 2,000 x 2,500 mm) enable a wide range of workpieces to be cut. There are three different main spindles available (with a power of 45, 54 or 64 kW) for machining different types of material. These main spindles can be operated in S1 continuous duty at high nominal torque of 2,000 to 4,000 Nm (maximum speed 4,000 RPM).
The ECOSPEED series shares many of the same features and equipment, but it differs in one key area: all high-speed machining centers are fitted with the Sprint Z3 parallel kinematic machining head, enabling five-axis simultaneous machining of aluminum. "With its maximum material removal volume of up to 10,000 cm3/min, the aviation industry still considers this to be the most productive machine concept for cutting structural components made from aluminum," said the spokesperson. "The solution also significantly reduces production times and costs. The tripod series can manufacture components from batch sizes of just one item to large-scale series production in a dynamic and accurate process with excellent surface quality."
According to the spokesperson, this series also features a modular design that allows it to be adapted to virtually any structural component of an aircraft. The horizontal machining centers are now available for a wide range of workpiece sizes as standard, from the ECOSPEED F HT for small and medium-sized workpieces (pallet size: 1,000 x 1,000 mm) and the ECOSPEED F for medium-sized structural components (maximum pallet size 8,000 x 2,500 mm), to the ECOSPEED 20210 with 120-kW spindle (maximum torque: 83 Nm/max., speed: 30,000 RPM), which has been designed for very long and large aircraft components (maximum 2,500 mm x 21,000 mm). Three of these large tripod-based machines are used for applications such as cutting the underwing panelling for the Airbus A320 from one piece of material in a single clamping process. The trio is designed to produce up to 40 shipsets or wing pairs a month. The weight of the final product is also reduced from 1,600 to 350 kg. By using a near-net-shape cutting process, there is no need for any reworking - even for this structural component, which is trimmed for a lightweight construction and measures around 20 m in length and 1.6 m in width.
