Introduction – CDRG Roller for Roll Thread Machine

A CDRG roller for roll thread machine is an essential precision tool used for the cold-forming of threads on fasteners, studs, and rebar. Unlike traditional cutting methods, roll threading displaces material, which strengthens the thread and improves its fatigue life. Our CDRG rollers, short for Carbide Donut/Ring Groove, are engineered from high-grade tool steel or tungsten carbide to ensure exceptional durability and consistent, high-quality thread profiles. These rollers are meticulously ground to deliver precise flank angles, pitch accuracy, and a superior surface finish, making them ideal for high-volume production in various industries, including automotive, construction, and general engineering.

Working Principle & Process Flow of Roll Threading

The process of roll threading involves forcing a cylindrical or tapered blank between a pair of profiled rollers under immense pressure. As the rollers rotate, the material of the blank is plastically deformed and flows into the grooves of the CDRG roller, creating the desired thread form. This cold-forming process not only produces work-hardened threads with improved shear strength but also a smooth, burnished surface that is highly resistant to wear. The typical process flow includes preparing the blank, setting up the machine (aligning rollers and adjusting pressure), the actual rolling pass with a suitable coolant, and finally, inspection to ensure thread pitch, major diameter, and profile are within specified tolerances.
