When purchasing a metal tube processing machine, most manufacturers face a common confusion: which is better, an NC pipe bender or a CNC pipe bender? Both machines are widely used in metal furniture, automotive piping, hydraulic engineering, and structural pipe processing. However, they differ greatly in automation, precision, production efficiency, and investment cost. To…

Introduction A leading automotive exhaust system manufacturer based in Jiangsu, China, specializing in high-performance stainless steel exhaust pipes for passenger cars and SUVs, faced critical production bottlenecks and quality inconsistencies with its old manual and semi-automatic tube bending equipment. To meet rising market demand, strict dimensional tolerances (±0.5 mm), and zero-defect requirements for stainless…

I. First, determine the four key parameters (which dictate the machine model size)1) Pipe Diameter (D) × Wall Thickness (T) (Most important)Model designations are typically based on the maximum pipe diameter:DW38 / 50 / 63 / 75 / 89 / 114 / 130Rules of thumb (carbon steel, ambient temperature, R ≥ 2D):Φ10–30: Choose DW38…
