Production Process
The steel rollers are made under the process of cutting, welding, turning, static & dynamic balance, CNC precision grinding and surface coating.
Usually the roller has critical requirements on the roundness, straightness, runout, con-centricity and cylindricity - that's why final precision grinding process is a must for a qualified steel roller. To ensure the high quality of the rolls, the company does precision machining & strict inspection.
Dynamic balancing is also a must for high speed working roller.
