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 ℃ rolling wheel processing, air Cooling Dongguan rolling wheels wholesale, then 480-500 ℃ X2h tempering hardness after heat treatment ≥45HRC, narrow bore 0.03-0.05mm, after grinding to achieve the pattern size requirements. Quenching and tempering the hole before rolling wheels arranged in cone quenching. Refurbished rolling machine rolling wheel wear adjustment must be synchronized rolling wheel, adjust the L and R rounds that coincide in the indentation of the workpiece surface. The synchronous adjustment is not accurate, would make the workpiece tooth disorder, the crumbs and ultra-poor, the high and consistent high workpiece center rolling wheel center (low 0.01 ~ 0.08mm), commonly used to adjust the method: roll rolling wheel wear after use, can be rubbed off teeth Dongguan rolling wheel suppliers to reduce their teeth, recalculated according to the above process parameters and re-open the teeth, making the renovation of the rolling wheel center distance in the machine within the allowable range repeated renovation. MassMutual rolling wheels, MassMutual rolling wheels (certified), rolling wheels provided by the Dongguan City Hengli Huai Hardware electronic processing.
