How to process laser engraving ceramic anilox roller?

1. Grind the new or old rolls to a diameter of approximately 0.5 mm smaller than the specified diameter.

2. The ground roller surface is sandblasted to increase the bonding strength between the coating and the base roller, and the bottom layer can improve the corrosion resistance of the anilox roller.

3. A ceramic coating (chromium oxide) having a thickness of about 0.3 to 0.5 mm is prepared by JCTPrint a plasma spraying method. When preparing a high number of anilox rolls, the coating porosity is usually required to be less than 1%.

4. Grind the ceramic coating with a diamond wheel to meet the outside diameter size and accuracy requirements, then polish the roll surface to a mirrored condition. Taking into account the corrosion problem, ensure that the thickness of the ceramic coating is above 300 μm.

5. Use a computer-controlled laser engraving machine to engrave the cells according to the specified number of lines, depth, and graphics. The ceramic coating at the mesh wall and the mesh wall prepared by the thermal spraying method is subjected to laser engraving and remelting treatment, and exhibits a smooth state with higher density and high hardness,JCTPrint so that the detachability and transferability of the ink are very good.

6. Polish the surface of the roller and confirm and adjust the volume of the cell. When the surface of the roller is in a mirror state, the friction between the anilox roller and the doctor blade and the embossing roller can be effectively reduced, and the wear is reduced. At the same time, the cell volume can be adjusted by polishing,JCTPrint .

7. Finally, by ultrasonic cleaning, the shape, JCT Print depth and cell volume of the cell can be restored, and the parameters are checked, confirmed and delivered.

Laser engraved cell shape

The laser is used to continuously engrave tiny cells on the ceramic coating. Since the cells are formed by the melting and evaporation of the ceramic coating at the laser beam, the cavity section has a semi-circular shape.

However, for the surface of the cell, the shape of the cavity of the engraved shape is arranged to form a honeycomb shape, a diamond shape and a spiral shape, and the shape of the cell is formed by the mutual interference of the melted ceramic cells.JCT Print As shown, the honeycomb shape of the honeycomb shape of 45° and 60° is 45°,JCTPrint .

Since the output control of the laser has accuracy and reproducibility, the number, depth, shape and angle of the cells can be kept consistent, so that a ceramic anilox roller of stable quality can be prepared.
