The types of slitting blades can be simply divided into the following types:

The first is special slitting blades. The slitting blades are generally matched with other equipment to help them complete special cutting tasks. In detail, it can be expressed in the following three aspects: 1. As a slitting blade for cold-formed forming line. 2. Such slitting blades are needed in the processing of steel structures. 3. The use of the blades of the plate flat line slitting machine is generally to help those cutting links that need to be completed quickly in the production process. The second is multi-purpose slitting blades. This slitting blade can also be divided into two forms to use: It is a high-precision slitting blade. When using this slitting blade, as long as the material is put in, the necessary cutting of the sheet can be completed. Not only can it be formed at one time, but also can be accurate. The most important thing is this When this kind of slitting blade is used, it is generally cut for the cutting process, so the use efficiency is very high. Normall

KNIFE MATERIAL

KNIFE MATERIAL: 1. The choice of tool material for steel composition mainly depends on the material to be cut. Since the steel will be cut by steel, the quality of the cut is always the main criterion for selection. This means that the material of the knife must be harder than the material to be cut. The second most important criterion for selecting a material must be the ability to maintain its cutting edge, that is, the cutting quality under load must be weakened anyway. Therefore, the material suitable for the tool is an alloy steel, which in principle can be hardened, can be deeply hardened and can withstand plastic deformation under pressure. 2. When selecting materials, one must decide which of these three main characteristics should be given priority, namely hardness, toughness and wear resistance, or which one of these three characteristics is desired and possible to be the best combination. 3. Since the thickness of the material to be cut can vary from 0.05 mm to 20 mm, the l

STORAGE AND MAINTENANCE OF SLITTER TOOLING

A sizable investment is made on these tooling. They have been manufactured to precision tolerances and should be handled accordingly. It is most important that the operator and set-up man realize how much money they are handling, when they pick up a knife or distance ring. The following points should be taken care of for getting the best out of the slitter tooling : (a) While setting the knives & distance rings, ensure that all the components are cleaned properly. Arbors should be cleaned & oiled. (b) When mounting, removing and storing knives, cutting edges and surface must be treated with extreme care. (c) Knives must be reground regularly. Please do not use blunt knives for the slitting operation - this will cause excessive load on the knife edge and there are possibilities of their chipping off. (d) All the knives should be ground in a set and variation in O.D. should be within 0.02 mm. (e) Since the material of the knives is hard, a suitable grinding wheel should be used f
