Urgent, I use the centerless grinder MT 1080B from Pioneer Machine Tool Factory. Outside diameter 13mm, the middle of the product is big and the two ends are small. What is originality? ...

Centerless grinding is comprehensive, and the so-called change is inseparable from it. It is nothing more than rounding the guide wheel and smoothing the grinding wheel. There is also the positioning of the center height, and the repair method of the guide wheel is also very particular. Whether the guide device is correct is very important and cannot be installed too straight. Otherwise, even if the three points are the same, a little will be cut off at both ends. Generally speaking, it is best to allow the middle part to be larger than the two ends. The angle should be in the right position, and the amount of knives should not exceed a trace. When there is also a central high pad, it is recommended to find a straight factory product pad between the two screws. It is impossible to make the product perfect and feel just right without any taper.
