What are the safety concerns of 115 golden star cutting disc when using them?
Balance problem--The imbalance of the cutting piece is mainly caused by the inaccurate manufacture and installation of the grinding wheel, which makes the center of gravity of the grinding wheel not coincide with the rotary axis. The damage caused by imbalance is mainly manifested in two aspects. On the one hand, when the grinding wheel rotates at high speed, it causes vibration, which is easy to cause polygonal vibration marks on the surface of the workpiece. On the other hand, the imbalance accelerates the vibration of the main shaft and the wear of the bearing. This can cause the grinding wheel to rupture and even cause an accident. Therefore, it is required that the sand office building with a straightness greater than or equal to 200mm should be statically balanced after loading the chuck. The grinding wheel should be statically balanced after being shaped and trimmed or found to be unbalanced during work.
Matching problem--The matching problem mainly refers to the installation and matching of the chuck and the grinding wheel. According to the standard requirements, the diameter of the grinding wheel chuck should not be less than 1/3 of the diameter of the installed sand office building, and the new grinding wheel should be replaced when the grinding wheel is worn to a diameter larger than the diameter of the chuck by 10 mm. In this way, there is a problem of matching the chuck and the grinding wheel. Otherwise, there will be such a situation that the “large horse-drawn carriage” causes waste of equipment and materials; the “small horse-drawn carriage” does not meet the safety requirements and is liable to cause personal accidents. Therefore, the reasonable matching of the chuck and the grinding wheel can save equipment and cut the material on the one hand, and meet the requirements of safe operation on the other hand. In addition, a cushion with a diameter larger than 2 mm of the chuck and a thickness of 1 mm to 2 mm should be installed between the grinding wheel and the chuck.
Bracket problems - brackets are one of the commonly used attachments for grinders. Adjustable brackets must be provided for grinders with a specified grinding wheel diameter of 150 mm or more. The distance between the grinding wheel and the bracket should be less than 1/2 of the size of the workpiece to be ground *, but * should not exceed 3 mm.
