What is Thread rolling / whirling?

Thread rolling / whirling capability for titanium components

Fastener manufacturing capability for Thread rolling / whirling, with cold forming, thread rolling, and 100% dimensional inspection.

Engineering Parameters & Capabilities

Thread rolling cold-forms threads by displacing material between two reciprocating or rotary dies, rather than cutting it away. Compressive residual stress at the thread root increases fatigue strength by 30–50% compared to cut threads, 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) is optimized for each feature.

Parameter	Primary Method	Alternative Method
Method	Cold-forming: material displaced, not removed	Thread cutting / milling
Fatigue Strength	30–50% higher than cut threads	Standard (notch-sensitive)
Surface Finish	Ra 0.4–0.8 µm; work-hardened	Ra 1.6–3.2 µm

Frequently Asked Questions

What titanium grades are suitable for Thread rolling / whirling?

Thread rolling / whirling can be performed on Grade 1, Grade 2, Grade 5 (Ti-6Al-4V), Grade 7, and other grades. The specific grade selection depends on the required mechanical properties, corrosion resistance, and end-use application requirements.

What tolerances can be achieved with Thread rolling / whirling?

Typical achievable tolerances for Thread rolling / whirling are Thread pitch: Class 2A/3A (UN) / 6g/6h (metric). Tighter tolerances may be possible depending on part geometry, material condition, and quantity. Our engineering team reviews each project to determine the optimal tolerance-cost balance.

What quality certifications apply to Thread rolling / whirling?

All Thread rolling / whirling operations are performed under ISO 9001:2015 — Quality Management System, AS9100D — Aerospace Quality Management, ASTM B265 — Titanium Strip, Sheet, and Plate Standard certified quality management systems. Full traceability documentation, material certifications (EN 10204 3.1), and inspection reports are provided with each shipment.

What is the typical lead time for Thread rolling / whirling projects?

Lead times for Thread rolling / whirling vary by complexity and quantity. Prototype quantities (1-10 units) can typically be completed in 3-7 business days. Production quantities require 15-25 business days. Rush orders are available for qualifying projects. Contact our sales team for a specific timeline.
