Which impacts do the vibration and creeping of the moving parts of internal grinders effect to the processing accuracy?
(1) creeping of moving parts of internal grinders.
The movement of grinding parts such as grinding table, grinding wheel rack and so on, is not homogeneous. when it is in micro periodic feeding or low speed continuous movement. It is generally called creeping. When this kind of phenomenon occurs, the feed in the grinding process can not be homogeneous, which affects the surface roughness of the workpiece.
(2) vibration of grinding machine.
There’s a vibration during the grinding process of internal grinders, it causes the relative position between the grinding wheel and the work piece having the periodic change, make the work piece surface have the vibration pattern, seriously affects the processing quality and the accuracy.
To improve the precision of the workpiece after grinding, in addition to making efforts to eliminate the impact of these factors, a reasonable choice, also must pay attention to a reasonable choosing of the positioning, clamping method, choosing and correct triming of grinding wheels and the reasonable choosing of grinding quantity and technology in the processing of work pieces.
What is the quality difference of the internal grinding machine? Chinese extensive development bonus has ended, and then to the high efficiency, high precision development, if your product is not fine,how to have a better reputation?
