Rolling wheels (Thread Rolling Cylindrical Dies) rolling wheel is mainly used for external threading rolling wheel manufacturers, specifications, including metric, American UNC & UNF, English (Wyeth), English works PT & PS, US-made pipe NPT & NPS, trapezoidal thread (imperial and metric) and bike thread and so on. The accuracy level is divided into a, 2 and 3. Another ring rolling wheels, special specifications, such as tooth type, pitch, number of teeth, etc. can also be customized according to customer needs. Quality rolling wheel is stable, directly affect the production rate, yield and efficiency of the thread, but also has a significant impact on the overall performance of the product. The company's rolling wheel system using imported high alloy tool steel, the wealthy and experienced professional vacuum heat treatment rolling wheels, so the uniform hardness, high stability rolling wheels wholesale, and then by a professional and rigorous painstakingly created, Whether tooth type, tooth pitch are very high precision. Rolling wheels rolling wire wheel bore within the high-frequency induction hardening and tempering using spiral inductors bore quenching, with intermittent electricity ways to make the hole about 0.5mm depth is heated to about 1050 ℃, air-cooled, and then 480 -500 ℃ X2h tempering hardness after heat treatment ≥45HRC, narrow bore 0.03-0.05mm, after polishing, the pattern size requirements. Quenching and tempering the hole before rolling wheels arranged in cone quenching.
