Expert circle meeting Precision machining of large size workpieces at GEORGhaus

On Dec.3, 2014 GEORG machine tool division was the host of the expert circle meeting „Precision machining of large size workpieces“ in cooperation with machine tool laboratory (WZL) of RWTH Aachen.

Logo RWTH AachenThe working group consisting of leading companies of Germany’s industry and WZL develops solutions around the topic machining of large size workpieces especially in the sectors wind energy, aviation and aerospace as well as turbine manufacture.  The demand for even closer tolerances of the workpieces combined with higher machining volumes of the machine tools do  often reach the limits of today’s manufacturing and measuring technology.

Due to their large variety in design customized large size work pieces are produced in small batches on highly specialized machine tools. Investments in such special machine tools, special measuring technology, high material costs and comprehensive transport and handling processes are the driving force for “First Time Right” and “Zero Fault” production.

Technology transfer from research stage into practical use can only be sustainably achieved if all challenging demands are known and can be transferred into a requirement profile for the solutions to be developed. In order to intensify the vital exchange between research and industry the expert working circle "Precision machining of large-size workpieces" was founded in 2012. Besides the partners from the research institute this consortium consists of 13 industrial companies.  Machine tool manufacturers and users as well as producers of measuring technologies and executing companies are represented here. In common projects the problems of industrial partners are  analyzed and problem solutions will be developed.

With its new machine type GEORG ultraturn MC GEORG is setting new standards with regard to efficient and precise machining of large-size and complex workpieces. This new machine type  makes it possible to completely machine a workpiece of up to 250 tons, 4000 mm diameter and 25.000 mm length including measuring of the workpiece on the machine itself.  According to Dr.-Ing. Wieland H. Klein the new GEORG ultraturn MC will be able to achieve shortest production times thanks to an innovative concept of machining heads for turning, milling and grinding operations in combination with a highly efficient tool changing robot.
