Compared with arc type structure,Chaoli liner type has more advantages.
Chaoli’s rectilinear guide system transmits the forming roll forces directly to the hydraulic cylinder, into the machine frame, and into the foundation. There are no load-bearing wear points or torsional stresses affecting roll parallelism and accuracy. This leads to a long service life, consistent parts, and low maintenance. The centerline of the forming roll is close to that of the pinch roll. This allows the flat areas associated with pre-bending to be small and consistent. In addition, Chaoli sizes the direct-acting hydraulic cylinders to pre-bend to the maximum rolling capacity of each machine.
