The main reasons for the normal wear of the 6 inch es cutting disc are mechanical wear and thermal and chemical wear. The former is the wear caused by the scribing action of the hard spots in the workpiece material, and the latter is the wear caused by the bonding, corrosion and the like.
1, bonding wear
Bonding is the bonding phenomenon that occurs when the tool is connected to the workpiece material to achieve the distance between the sub-pieces. It is also called cold welding. During the cutting process, due to the high temperature, high pressure and fresh surface conditions on the friction surface of the tool and the workpiece material, the bonding is highly likely to occur. When the relative motion continues, the bond point is broken by the large shear or tensile stress, generally occurring on the side of the workpiece material having a lower hardness.
2, abrasive wear
Abrasive wear due to the impurities in the workpiece material, the carbides, nitrides, and other hard spots in the material entanglement, which are caused by the scoring effect on the surface of the tool. At various cutting speeds, the tool has abrasive wear. At low speeds, other forms of wear are not significant, and abrasive wear is a major cause of tool wear. It is generally believed that abrasive wear is proportional to cutting.
The hardness of the cutting piece will face more and more new metal products in the future, so the hardness requirements of the cutting piece product are also increasing. The hardness of the product determines everything of the product. At present, the high precision brought by the super hard abrasive tool High-efficiency grinding results have been widely recognized.
There are many types of cutting pieces. Today we are talking about stainless steel cutting pieces. In order to extend the service life of stainless steel cutting pieces, it is necessary to carry out corresponding maintenance. Some details need to be emphasized here:
1. When the cutting piece is no longer sharp and the cutting surface is rough, it must be repaired in time. Grinding does not change the original angle and destroys the dynamic balance.
2. If the cutting piece is not used immediately, it should be laid flat or suspended by the inner hole. The other pieces or feet should not be stacked on the flat saw blade, and attention should be paid to moisture and rust.
3. The inner diameter correction of the cutting piece and the processing of the positioning hole must be carried out by the factory. If the processing is poor, it will affect the product use effect, and may be dangerous. The hole expansion principle should not exceed the original hole diameter of 20mm in order to avoid affecting the stress balance.
Stainless steel cutting blades are commonly used by technicians. For some steels that need to be processed and processed, stainless steel cutting blades are used. We are a fiber cutting disc Chinese supplier
