Mirror roller:
Materials: Select high-quality 45 # steel pipes, alloy steel pipes, precision steel pipes, etc.
Structure: Various structures such as inner spiral flow channel and jacket type are designed and processed. Heat treatment process is used for quenching and tempering. After processing by turning and matching, the red sleeve is hot welded, stress relieved, quenched, precision turned, precision ground, plated with hard chromium, and then ultra precision ground. It is precision ground and polished with American 3M abrasive.
Parameter: Roughness Ra0.005 (smoothness level 14 or above), without any vibration marks, stripes, or burrs. Straightness, runout, coaxiality ≤ 0.005mm. Cooling or heating temperature difference ≤ ± 1 ℃, thermal deformation
≤0.01mm。 After quenching, the hardness of the roller surface is HRC55-58, and after plating with hard chromium, the hardness is above HRC65.
Applied to: surface polishing and rolling of various plastic sheets, sheets, films, paper, leather, metals, fabrics, decorative materials such as PVC, ABS, PP, PT, PE, PC, etc.
