CDRG Threading Machine Supplier in Gujarat

CDRG Threading Machine Supplier | Leo Industries, Gujarat

CDRG Threading Machine Supplier in Gujarat

Looking for a trusted CDRG threading machine supplier in Gujarat? You’re in the right place. We supply robust thread rolling solutions for bolts, studs, rebar couplers and custom engineered parts. The CDRG (Carbide Donut Ring Groove) cold-forming process delivers stronger, chipless threads with superior finish and repeatable accuracy. From Ahmedabad, Gujarat, we supply machines, tooling and spares backed by expert guidance for fastener, construction and general engineering industries.


How Does a CDRG Threading Machine Work?

A CDRG threading machine forms threads by cold rolling, not cutting. Two precision CDRG rollers (dies) displace material into the thread profile as the workpiece rotates under pressure. This chipless deformation work-hardens the grain structure, producing high tensile strength threads, faster cycles and excellent surface finish compared to conventional cutting.

  • Always use PPE; keep hands/tools clear of rolling zone.

FAQs — CDRG Threading Machine Supply

Q1 What makes cold-formed threads stronger?
Cold forming realigns the material’s grain flow, creating dense, work-hardened threads with higher tensile strength and better fatigue performance than cut threads.
Q2 Can these machines handle different materials?
Yes—by adjusting pressure, feed and lubrication, you can roll threads on MS, alloy steel, stainless steel and select non-ferrous grades.
Q3 Do you supply rollers, dies and spares?
Absolutely. We stock CDRG rollers/dies, guides, bearings and essential consumables to minimize downtime.
Q4 Can you help in choosing the right model?
Yes. Share part drawings, material, thread spec (pitch, OD, length) and target output—we’ll recommend the suitable capacity and tooling.
Q5 What support is available after purchase?
Installation, training, preventive maintenance plans and quick-response service across Gujarat with genuine parts availability.
