Schaffner Machine Company specializes in standard and ACME rolled threads. We work with outside diameters up to 1″ on standard threads and 3/4″ on ACME threads. We can thru-feed bars up to 14′ in length or add as little as 3/16″ of thread to your part with in-feed thread rolling. As your complete machining solution, we can provide CNC turning and milling services for secondary operation on your threaded parts. Whether you need a dozen custom threaded eye-bolts or thousands of turnbuckles SMC is your complete thread rolling solution.
The benefits of thread rolling over cut threads
- Cost Savings: less raw material needed (typically 15% to 20% savings) and no wasted material
- Precision: smooth uniform threads over long runs
- Quality: superior thread finish extends the life of your parts
- Strength: cold-working the material during thread rolling results in increased tensile load, tensile stress, and structural integrity than in an equivalent cut thread (e.g. ¾-10 UNF 2A)
