Starrag: Machining the critical components inside a jet engine

“Everything is around cost per part at the end of the day.”

Fuel injectors and actuators may be small, but their impact inside a jet engine is enormous. With complex angled bores, tight true-position tolerances, and critical sealing surfaces, these components demand extreme accuracy.

In this chat with MTDCNC’s Paul Jones, Lee Scott of Starrag UK explains how machines – like the compact Heckert and the Bumotec 191neo – deliver the precision, speed, and single-setup capability needed to meet aerospace standards while keeping cost per part under control.
