Precautions For Installing The Grinding Wheel
The installation and use of fast working grinding wheel are dangerous. The grinder is one of the most commonly used machines in machinery factories. Whether the installation is reasonable and meets the safety requirements; whether the method of use is correct and whether it meets the safe operating procedures. These problems are directly related to the personal safety of each employee, so they must be paid enough attention in actual use.
When installing 4.5 inches grinding wheel, firstly, the safety quality of the grinding wheel should be tested. The side of the grinding wheel can be tapped with a nylon hammer (also with a pen), and the sound is crisp and there is no problem.
Positioning problem: Where is the grinder installed? It is the first problem to be considered during the installation process. Only when a reasonable and suitable position is selected can other work be carried out. Grinding machines are forbidden to be installed in the vicinity of the equipment and operators or in the places where people often pass. Generally, the larger workshops should be equipped with special grinder rooms. If it is not possible to set up a special grinder house due to the limitation of the plant topography, a protective baffle of not less than 1.8 m height should be installed on the front side of the grinder, and the baffle plate is required to be firm and effective.
Balance problem: The imbalance of 4.5 inches grinding wheel 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 shaft. The damage caused by unbalancing 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 fast working grinding wheel to rupture and even cause an accident. Therefore, it is required that the sand office building with straightness greater than or equal to 200 mm 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.
