Surface grinding machine grinding workpiece surface texture

Mechanical Parts &Fabrication Services ,Surface grinding machine in the process of early use of everything is normal, but after a while of grinding workpiece surface texture, and this is what reason causes? How should improve? Faced with the problem of customers so confused, here is a detailed explanation and solution.

Causes of vibration grinding grain has two kinds, one kind is forced vibration artifacts, another kind is the processing parameters are unreasonable, cause self-excited vibration artifacts.

Can understand it, the first kind of vibration is exist in the environment, even without grinding, plane grinding machine started, these vibrations. Just some vibration frequency close to the resonance frequencies of the workpiece, the grinding marks. The vibration of the suspected parts are installed in the bearing rotating parts, transmission belt and hydraulic components, etc. The second type, is a function of processing when a cyclical change, its frequency matches the resonance frequency of the workpiece, causing the marks. This kind of vibration can be cut by adjusting the process parameters. Or choose lower hardness, particle size coarse grinding wheel. Because if rigid comparison difference of surface grinding machine, with a sharp grinding wheel to reduce the grinding force, could also benefit from a certain extent, reduce the marks.
