The comparative tests on the Starrag LX 251 machining centre demonstrated the benefits of this вЂliquid toolвЂ™ coolant which is free from chlorine, boron and formaldehyde.

The result is impressive savings in overall roughing and finishing times by minimising the loading and unloading routines traditionally associated with multi-operation machining and how coolant (Synergy 735 from main event partner, Blaser) can improve tool life and promote environmental aspects. The on-machine demonstrations included: The production of compressor blades (with a blade length of 46mm and an airfoil length of 32mm) вЂin one goвЂ™, using a Starrag LX 021 machining centre that also utilised diamond wheels to grind the blade root as part of single set-up machining. These were showcased alongside several workstations featuring the latest in tooling, toolsetting and tool management, CNC system technologies, CAD/CAM and inspection routines, as well as in-process grinding, for example. While the spotlight was firmly on the new Starrag NB 151 for the machining of impellers and blisks of up to 600mm diameter and weighing 300kg, there was a range of other on-machine presentations that also caught the eye.

With a new blisk and impeller machine making its public debut, complemented by a host of technology developments and demonstrations on a range of machines and вЂpartnerвЂ™ workstations featuring innovative production and manufacturing technologies, this yearвЂ™s StarragвЂ™s Turbine Technology Days вЂ“ the seventh in the series вЂ“ left a record number of visitors (from 18 countries) with plenty to think about in terms of world-class manufacturing of turbine blades, blisks and engine casings. Aerospace Manufacturing hears more about StarragвЂ™s year-on-year turbine technology developments as witnessed during the companyвЂ™s Turbine Technology Days event held recently at its headquarters in Rorschacherberg, Switzerland.
