Grinding of turbine blade fir-tree root-forms improves at aerospace supplier JJ Churchill. Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.

The process and materials technology employed in the automated system is identical to that used manually, i.e. a belt grinding machine fitted with the same grit belts. The major change is that the blade is held by the RX130 robot rather than by hand. Two major challenges had to be overcome to successfully automate blade grinding. •
