Grinder on the connector slotting knowledge, the first two articles talked about the straight groove and the degree of slope of the groove approach, this slightly advanced sub-groove method, sub-groove is a common type of groove and straight Trough integration, common can be divided into the following types (of course, there are more complex types and more slots):

Making this type of slot, the technical aspects of the same with the straight slot, no longer say here, please check the previous article, the need to pay attention to is the processing sequence of the process arrangement, that is divided into several paragraphs Groove, the total need to have the order of processing, how to arrange the order is the most reasonable is the processing need to be considered, under normal circumstances divided into several paragraphs on the cut, from top to bottom order to repair the grinding wheel grooving, special circumstances separately consider.


Processing accuracy need to pay attention to the eccentric tolerance, the average workpiece is divided into points, where the slot on the need to pay attention to multiple points, the eccentric workpiece tolerance, the connector for the grooving inserts, eccentric Tolerance is generally controlled within 0.003MM, the more the number of segments, the more difficult the unified control of eccentricity accuracy, so when the sub-points need to be particularly careful.
