W11SNC-20x3000 Plate Bending Machine
W11SNC 3-roller Plate Bending Machine is a kind of double pinch plate bending machine. The top roller is hydraulic driving. The top roller is vertically and horizontally adjustable, and the two lower rollers are fixed. All of the rollers in alloyed steel are induction hardening and heat treatment. All of the rollers will be grinded and polished after induction hardening treatment.
