The shearing action of the slitting machine equipment is often directly affected by the quality of the blade itself. From the perspective of the producer, the plate sinew disc blade often seeks for tolerance and wear resistance and cuts the number of tool changes, but also to ensure the quality of the cutting section, generally choose higher hardness molybdenum alloy steel blade. After cutting a certain amount of steel strip, the blade edge gradually becomes dull due to wear.

Not only that, because of the long time in the cutting operation condition, so the blade steel will have a layer of fatigue, hardness increased significantly, so that the cutting quality of the scoring machine equipment is not ideal. In order to prevent the blade from becoming very weak, and then easy to rupture phenomenon, then it is necessary to timely grind to eliminate its tired layer, add edge sharp.

As for the user, choosing high-quality blades can not only significantly improve the operating efficiency of the strip machine equipment, but also save a lot of capital over a long period of time. Therefore, the use of each group of blades to establish a file. The original test data of the blade, the outside diameter before each grinding, and the amount of each grinding should be recorded to facilitate the detection of problems. So, when grinding, what problems need to be paid attention to? First of all, the machine tool used in grinding must be a high-precision cylindrical grinder.

Secondly, when grinding, we must pay attention to the reasonable control of the blade stack size, and pay attention to the number of grinding blades at a time should not be too much, so as not to affect the rigidity of the machine tool. In addition, the blade of the slicing machine blade, through a certain degree of wear and then grind, the depth of the tired layer because of the different thickness of the cutting plate, usually about 10% of the cutting thickness. For thin plate, the diameter of the outer circle should be reduced by 0.3 ~ 0.4mm.

In addition, we also need to pay attention to the fact that after grinding the blades of the slabbing machine equipment, the same set of knives with the same outer diameter should be stored in a special cabinet. Each group of blades can not be mixed, and the blade single side and double side shortcomings should be marked in the storage cabinet, so that the next time when the knife can be easily selected and used.
