(4) Product manufacturing range: diameter 300-800mm, length 3000mm.
(5) Product production process; material selection, roughing, tempering (quenching), semi-finishing, assembly welding, stress relief, finishing, static (dynamic) balance, electroplating, mirror processing, inspection, packaging and storage.
(6) Product accuracy: surface cooling temperature difference ≤±1℃, surface roughness up to Ra0.01 (smoothness level 14), to ensure the straightness, non-roundness, coaxiality of the roller surface, no vibration after mirror processing , Stripes, hairline, water ripples, etc.
The steel rollers are made under the process of cutting, welding, turning, static & dynamic balance,
CNC precision grinding and surface coating. precision galvanized steel roller, zinc plating steel roller
Usually the roller has critical requirements on the roundness, straightness, runout, concentricity and
cylindricity - that's why final precision grinding process is a must for a qualified steel roller. After
turning and grinding the rolls to the right size, it follows a final dynamic balance.
Finally based on your application field and unique requirements, the steel rollers need to be zinc plated,
painted, teflon coated, rubber coated, etc.
