What is CNC swaging/j-bend forming of spoke ends?

CNC swaging/j-bend forming of spoke ends capability for titanium components

Precision machining capability for CNC swaging/j-bend forming of spoke ends, utilizing multi-axis CNC centers with in-process inspection and SPC quality control.

Engineering Parameters & Capabilities

Press brake forming of titanium sheet uses CNC-controlled backgauges and variable-radius tooling to produce precision bends. Titanium's high springback (10–20° for Grade 5) requires over-bend compensation calculated from the specific alloy's elastic modulus, specifically for titanium components. Precision titanium components present unique challenges: Balancing dimensional accuracy with cost per part. Process selection (mill vs. turn vs. EDM vs. laser) optimized for each feature.

Parameter Specification
Method CNC press brake with air bending / bottoming
Springback (Gr5) 10–20° depending on R/T ratio
