1750 x 16mm and 2000 x 25.4mm type Edge Milling Machines are new equipment recently designed and developed by our company. They were designed based on a successful improvement of the cutter head transmission, row shear and lubrication, etc on previously imported equipment. The products have been put into operation on the spiral welding pipe production line of Shashi Petroleum Steel Pipe Factory. Currently we are designing a high speed edge milling machine for 24" ERW unit.
