how to control vibration in grinding machine

Measuring vibration on precision grinding machines

 · Self-excited vibration occurs only during grinding, due to grinding parameters, the process, and certain machine characteristics such as natural frequencies of the machine. During grinding, undulations/waves can start to form on either the workpiece or the grinding wheel as fluctuating forces excite a natural frequency on the machine.

There is a possibility for the initial vibration to be self-sustaining (unstable) and build up, with the machine oscillating in one of its natural modes of vibration. To make the increased capability of modern cutting edges, the cutting-tool materials available, powerful and stable machine tools, holding tools and cutting tools are required.

How to Reduce the Effect of Vibration in Production …

In a production-grinding operation, waviness on the part surface is a potential clue that the machine or process has developed a vibration problem. The effect might be seen in inspection, or if there is a lapping or polishing step, more time might be spent during that step removing the waves.

5Tips of Vibration Analysis in Grinding Machines|Newdiatools

If it is precision molding grinding such as plug-in connector molds or cutting grooves, it cannot be dressed because of the vibration of the machine. Because sometimes the grinding wheel needs to be dressed to a thickness of 0.1-0.13mm, if there are unstable factors of the vibration of the grinding machine, the grinding wheel exploded.
