The factors of abrasive wear include the following parts: Hard particles or protrusions that enter the frictional surface from the outside plow a lot of grooves on the surface of the softer material, and a phenomenon of wear caused by the migration of the material is called abrasive wear. The main factor affecting this wear: in most cases, the higher the hardness of the material, the better the wear resistance; the wear amount increases with the increase of the average size of the wear abrasive; the wear amount increases with the hardness of the abrasive Increase and so on. What is the cause of the sudden rupture of the China cutting disc for metal, the cause of the rupture of the cutting piece and the analysis of the solution, we all know that in the process of using the resin EN12413 cutting discs in production and processing, we often find the rupture of the cutting piece. What is the cause? How should the situation be solved? A machine ruptures when it is idling: the cutting piece is idling for one minute when it is used in the cutting table. There are two main factors in the process of rupture. One is that the cutting piece is a poor quality product itself and does not reach the cutting line speed. In addition, the cutting piece aperture and the cutting table shaft are not equipped, and there is a large stress during assembly. The two cutting pieces are broken during use: we often see that the cutting piece is normal when it is used, and the grinding wheel is broken when the cutting is performed in the normal 1/3 state. The analysis may be due to the following reasons: the flatness of the cut piece, the unevenness of the cut piece, the high hardness of the cut piece, and the lack of toughness of the cut piece resin. How to choose efficient and safe wear-resistant cutting products! Here are some of the factors that are preferred in the selection process! 1) It can be used for good grinding and cutting efficiency without filling. Moderate softness is suitable for grinding and cutting operations with curved work. 2) At the same time as working, the burrs of the working surface are removed, and the working surface is smoothed. 3) It has the effect of air cooling, which can significantly avoid the phenomenon of heating and burning on the working surface. 4) Safe, sharp, wear-resistant, non-heating, non-burning, power saving, labor saving, time saving, high efficiency and economical 5) Satisfy the customer’s requirements for non-standard customization, and can carry out various non-standard customization according to the customer’s drawings or samples. Due to various reasons in the manufacture and installation of the dicing sheet, the center of gravity of the dicing sheet often does not fit with its center of rotation, which causes the grinding wheel to vibrate at high speeds, which affects the processing, and causes the rupture of the dicing sheet when it is severe. The machine tool is damaged, so the cutting piece must be statically balanced after it has been mounted on the flange. After the cutting piece is mounted on the flange, the flange is placed on the mandrel and placed on the gimbal rail. If it is unbalanced, the heavier part of the cutting piece will always turn to the bottom, move the balance block position inside the ring tip of the flange, balance the center of the cutting piece, and repeat until the cutting piece is free on the guide rail. The position can be still, and the cutting piece reaches a static balance. When installing a new cutting piece, the cutting piece is statically balanced twice. After a static balance, install the grinder and trim the shape of the cutting piece with a diamond pen, then remove the cutting piece and perform a static balance before installation.
