| Automotive fuel tanks and processing is a deep hole machining areas can use ready-made steel pipes, the first heat treatment after welding materials to meet the requirements of the mechanical properties. Deep hole machining equipment must be used when processing the left margin to the size of the mill will bore deep hole Yan Yan honing finishing. The general cylinder factory right steel tube re cold drawn mainly to off-the-shelf procurement tube. Small cylinder used at both ends lever fixed cylinder head, and on the hardness of the material requirements, to use steel processing and honing. [2013/1/29 16:19:20] |
