Note the use of rolling a wheel, rolling machine accuracy, vibration, does not operate under normal service; 2, rolling die on the bit errors, are rolling pieces of axial displacement occurs, tooth pattern by cutting and squeezing two species of stress; 3, is uneven size rolling green silk thread rolling round supply, the surface is not clean, there is foam wheel, scale and filth; 4, is unevenly rolled pieces of hardness (8.8 bolt should be 27 ~ 30HRC; 10.9 level applications in 35 ~ 37HRC), sometimes because of mismanagement will prevent without tempering high hardness (50 ~ 55HRC) quenching and tempering pieces blend into pieces, and its hardness and rolling wheel teeth cutting edge hardness similar pattern rolling wheel factory outlets, resulting in chipping. 5, did not join when rolling lubricant, causing friction, so cusp rapid temperature rises above the fire rolling cycle of temperature, excessive temper softened tooth pattern, the occurrence of back teeth, dental heap failure; 6, rolling wheels the factory must be fully demagnetized, leaving residual magnetism, work fine iron absorption due to tooth pattern foam will accelerate wear failure. Rolling wheels rolling wheels on how to use correct? Rolling wheels rolling machine that is on the use of metal plastic deformation method of rolling out a tool thread. So how do the proper use of rolling wheels, with the benefit of Xingtai rolling wheel manufacturers for you to sit down briefly rolling wheel manufacturer, we want to help you. 1, rolling machine accuracy, vibration, does not operate under normal service; 2, rolling die on the bit error, is rolled pieces of axial displacement occurs, tooth pattern by cutting and squeezing two kinds of stress; 3, Rolling green silk thread is uneven size, the surface is not clean, there is foam wheel, scale and filth; rolling wheel supplier, rolling wheels, MassMutual rolling wheels from Dongguan City Hengli Huai Hardware providing electronic processing.
