Dörries Scharman builds universal machining centre for KSB; five main axes and further two via trunion device and facing head; additional highlights: automatic pick-up magazine equipped with a universal angled milling head to allow full 5-sided machining, chain magazine for 80 tools and NC table. Machining centre replaces in KSB Workshop two boring mills and offers exceptional machining options.
The best way of tackling a demanding project is for customer and machine tool builder to work together. That is why pump manufacturers KSB and Dörries Scharmann teamed together to replace two horizontal boring mills with an ECOFORCE 1 HT2 machining centre, and locate it between two supporting factory floor foundations.
The plan was to deploy the new machine for short run and single part manufacture (up to a maximum batch size of 5) for all kinds of components – from small welded structures to very heavy barrel-type pumps. KSB“s production planner Michael Eilers explained: „The main feature of the horizontal boring mill is that it can do everything – drilling, turning, milling and even thread cutting.“ The small footprint required for the machine represented something of a challenge for Mönchengladbach-based Dörries Scharmann Technologie GmbH (DST), a subsidiary of the Starrag Group. „A machining centre is usually equipped with a pallet changer, so that loading can take place in parallel with machining time,“ explained DST sales manager Roland Wozny. „And that means a correspondingly large tool magazine“. But because space at the Frankenthal factory is at a premium KSB wanted to include a chain magazine for 80 tools, along with an automatic pick-up magazine.
The magazine can pick up the automatically interchangeable and balanced facing head which enables turning to take place on the machine. At a high output rate (maximum torque 5,000 Nm, and revolution rate of up to 300 rpm) and with cranked tools, the ECOFORCE can even economically cut heavy workpieces weighing 12 metric tons with diameters of up to 1,250 mm. The automatic pick-up magazine is also equipped with a universal angled milling head to allow full 5-sided machining. The ECOFORCE has a few extra features that turn it into an all-round machine. An additional sub-unit made it possible to implement an additional axis on the machine table. And an additional NC table (clamping surface 800 mm x 800 mm) is available to machine very small workpieces.
With all its machine tools KSB values ease of operation and good access to the workpiece so that measurements can be carried out. So the machine was equipped with an automatic sliding platform system – well secured to prevent accidents – with two very large right-angled sliding doors to allow the table to be loaded from a factory crane. Overall, DST“s customer in Frankenthal was very pleased with the project. Michael Eilers said: „I was very struck by the way the whole project was implemented smoothly and without prolonged discussion. Not every machine tool manufacturer is able to achieve that.“
