Hydraulic punching units and precision steel pipe mill production cycle capillary before the procedure, but also squeezing precision steel capillary first unit production processes. Punching process is mainly to change the tube (ingot) cross-sectional shapes (square wave by a square or circular shape change is), but little change in cross-sectional area, that is basically no or only minimal deformation (extension ). Hydraulic punching machine has vertical and horizontal points, generally for shorter vertical tube (town 1.5mm), for a longer horizontal tube or ingots. Vertical water (liquid) when the pressure punching, punching in order to reduce bias, generally square tube before punching through the first tube forming machine stereotypes. Extruded pipe mill is generally used round tube, advance through the car Cylindrical (Barker ) to ensure the accuracy of the diameter size; while the stainless steel or high alloy steel, but also in drilling a through-hole tube (# 20-30mm), to ensure uniform thickness. Or high-alloy stainless steel precision tube is not punching but reaming. Liaocheng dry one hundred million Industry Co., Ltd.
