在铝合金简体薄壁工件的机械加工中,时常出现工件的内、外圆形状误差过大的现象。图中所示为我厂加工的某型航空产品零件(材料:LD7)。由于内孔表面需经硬质阳极化后抛光,为防止抛光时将硬质阳极化层磨掉,内孔的圆柱度须严格控制。但在加工时,出现内孔圆柱度超差率达30％左右,报废率达3％～5％。对此我们进行了认真地分析,改进了加工工艺,使效率和质量都有很大提高,经济效益非常显著。
Aluminum thin-walled parts in the machining of the workpiece, the workpiece often appear inside and outside the shape of the error is too large. The picture shows a certain type of aviation product parts (material: LD7) processed by our factory. As the hole surface to be hard anodized after polishing, in order to prevent polishing the hard anodized layer worn, the inner cylinder of the cylinder to be strictly controlled. However, in the processing, appear within the cylindrical hole super-rate of about 30%, the rejection rate of 3% to 5%. In this regard, we conducted a careful analysis, improved processing technology, so that efficiency and quality have greatly improved, the economic benefits are very significant.
