Thread Whirling
Precision Thread Whirling Services in the UK
Thread whirling is a high-precision method used to cut internal and external threads with excellent geometry and surface finish. At Halifax Rack and Screw, we use advanced Leistritz and Binns and Berry technology to form difficult thread types with accuracy and repeatability.
Thread whirling is ideal for materials that are hard to machine using conventional threading techniques, such as titanium, Inconel and stainless steel. The process is widely used in the aerospace, medical, and oil & gas sectors.
Accreditations:
ISO 9001:2015
External Threading
Used to manufacture screws, lead screws and custom shafts with large-pitch or multi-start threads. Thread whirling ensures concentricity and lead accuracy, even on long workpieces.
Internal Threading
Internal thread whirling is ideal for bores that are deep, narrow, or difficult to reach with standard tooling. It is used in high-spec parts where thread precision is critical, such as hydraulic fittings, aerospace couplings and surgical instruments.
Benefits of Thread Whirling
- Deep access: Threads deep holes with minimal deflection
- Excellent surface finish: Reduces need for secondary finishing
- Material flexibility: Effective on titanium, stainless, Inconel
- Repeatability: Tight control of lead, pitch, and depth
- Volume-ready: Suitable for small batches or production runs
