Roller maintenance:

When it comes to the maintenance of roller, first of all, it is necessary to pay attention to the regular cleaning of roller dust and other foreign matters, after that, it should pay attention to the regular inspection of roller shell and end cover welding is firm; Then, on the roller in the maintenance, should also pay attention to maintain good lubrication, reduce the loss of wear; In use, should also avoid overload operation, extend the service life of the roller.

Requirements for roller making:

The roller shall be rigid enough to ensure that the bending deformation does not exceed the allowable value under heavy loads. Roller surface should be paid attention to have enough hardness, generally required to reach HRC50 degrees above, with strong corrosion resistance. The coating has the ability of anti-spalling to ensure the roller working surface has good abrasion resistance and corrosion resistance.

Later on the work surface of the roller should also pay attention to the processing of quite fine, in order to ensure size accuracy and surface roughness. The roughness should also be maintained above Ra0.16, and there should be no pores or grooves. The wall thickness of the working surface of the roller must be uniform, otherwise the temperature of the roller surface will be uneven, affecting the quality of products.

Roller in the process, should pay attention to the thermal conductivity of the material should be pay attention to the good, on the one hand, this time also will note must be to use chilled cast iron, cast steel or under special circumstances should be adopted is chrome molybdenum alloy steel, thus can ensure whether it's in the heating or cooling of time, can achieve the goal of fast evenly.

Magnetic force of magnetic roller:

After selecting the high strength permanent magnetic block up to the standard, it is important to note that the normal magnetic roller and flexible blade can withstand the rotary speed up to 300 meters per minute. On the magnetic roller on the surface of the roller body locally placed superstrength permanent magnetic block, in this regard, it will make the flexible blade edge more firm and withstand higher speed rotary die cutting.
