Thread Rolling Checks/Verification
- Thread rolling is a method for producing an external thread on a generally ductile material such as titanium, steel, aluminium or copper by forming the thread between rolls under high pressure.
- The thread produced is generally stronger than the original base material, is uniform and produced to very tight tolerances.
- The threads are normally rolled cold but can in certain circumstances be carried out at elevated temperatures.
Sectors using rolled threads include:
- Aerospace
- Nuclear
- Automotive
The cold formed properties of the resulting thread include:
- A precise smooth finish
- Faster production method than thread cutting or grinding
- Higher fatigue resistance
- Higher thread strength
- Higher shear strength
- Higher thread repeatability
- Lower costs per thread
- Absence of defects causing by thread cutting such as tearing and chipping
- No metal is lost during the process, saving wastage
- Testing can be carried out to most international standards including specialised aerospace and defence related specifications.
- UKAS and Nadcap accredited testing and certification, as well as specific aerospace approvals.
- Full production or performance testing.
- Testing may include the following:
- Visual examination
- Metallographic examination
- Hardness testing
- Shear testing
- Tensile testing
- Fatigue testing
- Alpha case detection
- All tests carried out on a single site
