Thread rolling is a cold forming operation used to form external threads in a blank. During thread rolling, a hard die is pressed on a rotating workpiece (also known as blank), which is connected to the thread rolling machine. The material on the blank is shifted to form the root of the thread, and the displaced material flows outward. The thread form is the shape or profile of the thread rolled into the blank. For quality hydraulic two die thread rolling machines we made, you could ask for the more specification and competitive quotation through our sales specialist. Certainly, with more than 10 year industry experience, we already have exported quality heavy-duty cylindrical thread rolling machines across the world for many years.
