Analysis of three major factors that cause vibration of grinding machines

There are many reasons for the vibration of the grinder. The following are the three reasons for finishing the grinder:

First, first check the ground level. If the level of the machine ground screw is not adjusted properly, it will cause the machine to resonate. Because sometimes the ground level of the processing site is not very good, we must adjust the horizontal screw to make the machine reach an uneven height. First of all, we must check whether each screw of the foot is in place into the floor mat. Before and after using the spirit level to lay down, whether the left and right are horizontal, tighten the screws.

Second, if the above actions are performed, the vibrations are still not eliminated. We should check whether the ground floor space is too low. If the ground is a terrazzo or a paving slab, it will be relatively strong. If it is cement ground, the ground will be empty. Cause resonance. How to deal with this situation? Go to the rubber hardware store to buy a few black rubber pads, about 6-10 millimeters thick, 10 centimeters in size and slightly larger than the size of the floor mats. Loosen the anchor screws and place the rubber pads under the horizontal floor mats. It can play a great role in shock absorption.

Third, if the vibrations are not eliminated after the above actions are taken, we must check the problems of the grinder sand bowl and the grinding wheel fixing flange. The first is the grinding wheel. Since the quality of the grinding wheel on the market is uneven, there are generally two factors that affect the vibration of the grinding wheel: one is that the grain size of the grinding wheel is not uniform, and the center of gravity of the grinding wheel is not stable, causing vibration; the other is that the inner hole is not standard large. For example, our grinder flange diameter requirement is 31.75, and if the grinding wheel is 32, it will jump up and down to cause vibration. We must ask the specifications when we purchase the grinding wheel. It is recommended to buy a good quality grinding wheel. First, the bad grinding wheel affects the processing effect; Second, the risk of cracking and explosives occurs in the grinding process; Third, the poor balance of the grinding wheel will badly affect the life of the grinding spindle.
