Combined with an internal combustion engine coupled parts precision machining project eyelet hole processing technology

Heng plating with low life, the size should not be guaranteed, processing technology immaturity, etc., have not been satisfactorily resolved. These problems seriously restricting domestic small hole finishing technology and development. Therefore, this article combines an internal combustion engine coupled parts, precision hole  cutting tools , hole  grinding wheel  technology used in electroplating honing with the preparation and application of technology has been studied, the paper in the following  cubic boron nitride  analysis. Analysis summarizes the domestic small diameter deep hole processing technology, introduced the current hole processing technology and the latest research in this area in the domestic situation.
