Starrag's revolution in titanium machining with hydrostatic guideways on new STC 1250 HD machining centre

Starrag is set to revolutionise titanium machining performances with its new ultra-rigid and robust STC 1250 HD horizontal machining centre, the first machine in its large-capacity class with hydrostatic guideways for zero friction/non-stick/slip movements. The machine – which will be one of the highlights of Starrag’s EMO stand - provides users with:

- Improved roughing times - reducing roughing times by up to 50% and decreasing overall machining times by up to 30%.

- Reduced energy consumption rates during machining of 33%.

- More dynamic finishing and therefore more precise parts courtesy of higher acceleration and jerk rates plus frictionless/no micro-vibration in the X axis. Hydrostatic guideways also mean reduced maintenance demands compared to conventional box guideways.

While full details of the new machine will be available soon, recent demonstrations not only showed how the hydrostatic guideways enable the 12-tonne column to be easily moved by hand, but they also proved the machine’s impressive machining performance. Using porcupine, face and Starrag’s own-manufactured solid carbide milling tools on a Ti6A14V frame door forging measuring 80 mm deep x 300 mm wide and 1,220 mm long, the machine also achieved roughing cuts up to four times deeper than would be traditionally achieved.
