Volume delivery of titanium alloy precision parts to an aerospace company

In the first half of 2026, we completed volume delivery of titanium alloy precision structural parts for an aerospace equipment company, delivering 12 batches totaling 860 pieces with a 99.5% dimensional pass rate.

Where the difficulties lay

Titanium alloy has low thermal conductivity and a small elastic modulus, so cutting heat concentrates at the tool edge, easily causing rapid tool wear and workpiece surface burns; thin-wall structures deform easily under fixturing and cutting forces, making wall thickness uniformity hard to control.

How it was solved

First, 5-axis simultaneous machining in a single setup completed the main features, reducing deformation and positioning errors from repeated fixturing; second, high-pressure cooling with titanium alloy-specific cutting tools controlled cutting zone temperature; third, roughing and finishing were separated with intermediate stress relief to release deformation before finishing.

Delivery results

The first articles of all three batches passed customer acceptance on the first attempt, with SPC sampling during the volume stage and key dimension process capability index Cpk≥1.33. The customer has continued entrusting us with key structural parts for the next two models.
