W12NC-50x3000 Four Rollers Plate Bending Machine

W12NC 4-roller Plate Bending Machine is a type of double pinch plate bending machine. Each of the rollers is separate driven. Rollers rectilinear slide ways coated with antifriction material, no maintenance, suit to heavy duty loading, smooth and stable positioning. Spherical roller bearings are equipped on the rollers. 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.
