在机械装修过程中,经常把铜套镀入孔座,铜套对孔座一般为过盈配合。在常温下,铜套压入或打入孔座时。铜套内孔要收缩。为保证收缩后的铜套与轴的动配合间隙,一般采用铜套内孔留加工余量,镶入后再进行镗削加工;无法镗削的就用手工刮研,费时费力,工效不高。 In the mechanical decoration process, often copper plated into the hole seat, copper sleeve hole seat is generally interference fit. At room temperature, copper sleeve into or into the hole when the seat. Copper sleeve hole to shrink. In order to ensure the contraction of the sleeve and the shaft after the move with the gap, the general use of copper sleeve leaving the remaining allowance, set in after boring processing; can not boring on the use of manual scraping, time-consuming and labor-intensive, inefficient .
