Training dedicated to cold expansion of fastener holes (cold working) according to BACC 5060 and equivalents. 3-day programme to qualify your technicians on split sleeve and split mandrel — primary aerospace structure, retrofit and SLEP applications.
Training is delivered on original FTI tooling (Split Sleeve Cold Expansion™, ForceMate®) — Kronos is an official Fatigue Technology partner — and also covers the split-mandrel process for WCI-equipped shops.Cold expansion — 3 days — BACC 5060
