The vibrating grinder, hence the name, produces vibration. However, in some daily processing, products that require high precision are often stopped for further processing, and excessive vibration will lead to processing failure.
So how should we deal with and prevent the vibration of the surface grinder?
Vibration grinder
1. First check the ground level. If the level of the anchor screw is not adjusted properly, it will cause the resonance of the machine tool. Because sometimes the ground level of the processing site is not very good, it is necessary to adjust the leveling screw to make the machine tool reach an uneven height. First, we need to check whether each screw of the foot is in place in the foot pad. Use a level to lay down the front and rear, left and right after leveling, and then tighten the screws.
2. If the above actions are stopped and the vibration is still not eliminated, we should check whether the ground floor is too empty. If the ground is terrazzo or the paved floor board is relatively firm, if it is a cement floor, the ground is very empty, which will cause Resonance, how to deal with this situation? Don't worry, go to the rubber hardware store and buy some black rubber pads, about 6-10mm thick, 10cm in size and slightly larger in size for the foot pads, loosen the foot screws, and place the rubber pads on the level feet Under the pad, it can play a great shock absorption function.
3. If the vibration is still not eliminated after the above actions, it is necessary to check the problems of the grinding machine sand and the fixing flange of the grinding wheel.
The first is the grinding wheel. Due to the uneven quality of the grinding wheels on the market, there are generally two factors that affect the vibration of the grinding wheel: one is that the particle size of the grinding wheel is uneven, and the center of gravity is unstable when it rotates, causing vibration; the other is that the inner hole is not standard and too large. When buying grinding wheels, we must ask about the specifications. I suggest that you buy better grinding wheels. First, a poor grinding wheel will affect the processing effect; second, it is easy to crack and explode during the grinding process; third, a poor grinding wheel has poor balance effect It will seriously affect the life of the grinder spindle.
Then there is the grinding wheel fixing flange. When you lift the flange, everyone will think of balance. In fact, the flange of a small precision hand grinder does not need to be balanced. The premise is that you must use imported precision flanges, generally new flanges. When you buy it back, there are three small balance blocks on it. You remove them, install the flange directly on the grinding wheel, and then repair it. The grinding wheel will be naturally balanced. Buy a few more flanges and install grinding wheels of different specifications. The next time you use it, it will save time and save time and improve efficiency.
4. It is the processing environment. It is impossible to place machine tools such as punching machines and lathes around the same workplace, which can easily cause resonance. How to judge, it is very simple, you only need to stop the grinding machine, start the punching machine or The lathe, if the hand touches the grinder, if there is vibration or numbness, it is affected. The solution is to place them in separate workshops.
5. If you stop the above series of actions and still can't eliminate the vibration, then it may not be the category you can handle. It may be that the spindle of the grinding machine vibrates itself for a long time, and the bearing or motor inside is broken. It may also be the structure and the structure of the machine tool. If there is a problem with the assembly, it is necessary to notify the manufacturer to deal with it. Compared with the plane grinder, the vibration of the vibration grinder will be larger, because the design principle of the vibration grinder is that the vibration is the working power to grind and polish.
