Video of Interesting Turbine Blade Workholding System
This clamping system is an automated steady rest with measuring capability that stabilizes the five-axis machining process of very long turbine blades.
Five-axis machining of long turbine blades can be tricky, especially in terms of securely fixturing them for effective milling. The Starrag Group demonstrates an interesting blade workholding system in this video. The clamping system is an automated steady rest with measuring system to stabilize the machining process. It offers adjustable clamping devices that can be used on raw and finished blade areas and can accommodate different blade families. The company says rigid clamping using this system results in longer tool life, lower tooling costs, higher material removal rates, improved contour accuracy and overall lower unit costs.
