Overcoming Cobalt Superalloy Machining Challenges
Cobalt-based formulations combine extreme work-hardening tendencies with high abrasive carbide concentrations. AXALLOY deploys rigid multi-axis platforms, specialized carbide grades, custom tooling geometry, and high-pressure flood coolant strategies to ensure zero thermal degradation, strict dimensional repeatability, and burr-free edges.
5-Axis Contour Milling
Rigid multi-axis milling for high-aspect structural parts, medical implants, wear rings, and turbine geometries. Minimizes setup errors and achieves complex 3D profiles in single operations.
