JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Asia 2012 - Among the latest optimized processes to emerge from Sandvik Coromant's R&D team is one-shot drilling of composite/metallic stack materials (titanium/CFRP/aluminium) using power feed machines.
This avoids the still commonly employed three-stage process that requires pre-drill, drill and reaming operations to achieve the necessary surface and dimensional quality.
One of the solutions is a helix flute drill based on a veined PCD point with a specific geometry. Reductions in cycle times are impressive, all while maintaining strict criteria based on Cp/Cpk targets for surface quality and exit burr.
Is it the biggest breakthrough yet in composite drilling? Ultimately, JEC visitors can decide for themselves, but test results indicate the potential for significant competitive gain.
Sandvik Coromant works closely with partner company, Precorp. Together, they deliver state-of-the-art, co-branded drills and milling cutters for improved performance with machining composite materials which can be used in all types of machines.
