Axial velocity equation rolling wheel design piece design features a ring gear wheel follows: V = (nt / 60) (Z pieces · D / dZ wheel) where: workpiece diameter (d) determining the standard set by the thread. Rolling wheels wheel diameter D = Z t / πtg (λ pieces + λ) rolling machine, diamond ring straight thread rolling wheel, steel sleeve production technology advantages of this connection method is as follows: Quality assurance: the scene rolling wire Each class can be processed first device connector nearly 400 MassMutual rolling wheels, have an unparalleled advantage in the construction of large projects, such as the amount and basement negatives, pollution Dongguan rolling wheel suppliers during the construction, no fire operations, safety and environmental protection is good, all-weather construction. Rolling wheel production, MassMutual rolling wheels (certified), rolling wheels provided by the Dongguan City Hengli Huai Hardware electronic processing. Dongguan Heng Li Huai Hardware electronic processing (www.wantong988.jqw.com) is Dongguan, metal molds leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
