What are the reasons for grinding machine vibration

2025-04-10

What are the reasons for grinding machine vibration? There are multiple reasons that can cause grinding machine vibration, and the following are the three main reasons:1. Check the horizon.If the level of the foundation screws of the machine tool is not adjusted properly, it will cause resonance of the machine tool.2. Check the floor.If the above actions have been taken and the vibration still persists, we should check whether it is due to the virtual space on the ground floor. If the ground is terrazzo or paved with floor tiles, it will be relatively solid. If it is a cement floor, the ground will be very weak and cause resonance.3. Check the grinding wheel and flange.If the vibration still persists after the above actions, we need to check the problem of the grinding wheel and the flange fixing the grinding wheel. First is the grinding wheel. Due to the uneven quality of grinding wheels on the market, the...

How to repair the grinding damage on the spindle of an external cylindrical grinder

2025-04-10

How to repair the spindle wear of an external cylindrical grinder?1. Add one gasket to the left end of the skeleton oil seal installation position and the inner side of the left end cover of the main shaft, so that the area where the oil seal grinds the deep groove is blocked or staggered by the gasket. Due to the limited installation position of the left end cover of the main shaft, the thickness of the gasket cannot be too thick, but it must ensure that the position of the grinding deep groove can be avoided. Therefore, calculate, design and manufacture one gasket.2. Dismantle the main spindle of the grinding wheel holder, weld the deep groove ground by the main spindle, and grind it after welding; Or disassemble and spray coat. For this malfunction, spray coating was chosen, and after spray coating, secondary processing is required. The requirements for accuracy and coaxiality tolerance during the grindi...

Question and answer on outer ring grinding machine

2025-04-10

Q&A on the outer ring grinder. 1、 Q: What is the precision and roughness of cylindrical grinding machine processing? Answer: As long as the precision of the measuring tool is high, the machining accuracy of the cylindrical grinder can reach 0.001mm, and the roughness can reach Ra0.40020. 2、 Q: What is the size of the bearing system between the outer cylindrical grinder and the bearing? Answer: Bearing shells belong to sliding bearings. The spindle speed of the ordinary cylindrical grinder grinding wheel is very high, and the radial force caused by the grinding force is also very large. The rolling bearings are no longer "capable". Installing gaps that are too large or too small can affect the establishment of sliding. 3、 Q: What is the reason for the large vibration generated by a faster feed of the cylindrical grinder? Answer: The vibration comes from the motion part: 1. Check ...
