1. Introduced original mirror polishing machines, utilizing 3M's polishing abrasive belts from the United States, achieving a surface roughness of Ru0.001 (equivalent to China's surface finish grade 14).

2. Materials for processing are selected based on customer drawings or requirements, utilizing 45# seamless steel tubes or alloy steel tubes, with a channel or jacket installed in the middle, ensuring a temperature difference of no more than ±1℃.

3. The roller can reach a hardness of HRC 55°-58° after heat treatment (depending on the material), with a chrome hardness of HR65° or above. The thickness is 0.06mm-0.20mm on one side (as per requirement), with less than 0.01mm of thermal deformation.

4. Suitable for various plastic sheet materials, boards, leather, paper, and glossy finishes.

5. Technical Precision, Temperature: ≤±1℃ (Thermal Deformation ≤0.01mm)

Flatness, runout, and coaxiality: ≤0.01mm
