The service life of the stainless steel pipe fittings there's a lot of influence factors: the introduction about the different processing methods, processing elbow, when tapping to thread in size, may be two taps on the end face touching one another, the reason is that tap base is longer than the other.
In this case you need to tap end face grinding is short, but end face grinding after short may be harmful to the function of the use of tap. Tap end face grinding short before and after the relationship between tap and processed workpiece, end face grinding after short tap thread department cannot normal import hole, but by the end pressure in hole, which affects the function of the use of tap.
In the mill, stainless steel stamping elbow pipe fittings on the whole length of the thermal mechanical historical changes obviously, especially in micro stamping stainless steel elbow pipe fittings produced, will strongly affect the finishing mill on the degree of recrystallization and grain growth and precipitation, and causes the entire stainless steel stamping elbow pipe length on the ultimate microstructure of severe changes and function. For the first guide grinding must keep the original geometry shape, it is best to use tap cutting grinding machine for grinding. Longer method is the best solution to tap base according to the specific requirements of the processing thread custom short base level of the tap.
To solve these problems, some users have to oneself to tap orientation department before grinding, grinding before and after the tap before orientation. Because the front guide of the grinding after the appearance change, still affect the tap to use function. Solution to this topic is: mill including a reciprocating roughing mill and mill a reciprocating 4 roll finishing mill. In the transmission line on both sides of the finishing mill installed two hot roll mill. Output table usually include a set of laminar flow cooling system and a coiling station.
