某机座舱侧位锁零件用GCr15钢制造,图纸要求表面镀铬,经常发现裂纹,裂纹的产生均在零件磨削、磁粉探伤、镀铬处理后,零件装配之前,因此给飞机的装配进度和质量带来了困难和隐患,为提高零件生产质量,杜绝裂纹的产生,对零件的热、表处理工艺进行了分析验证并采取了一系列预防改进措施,通过几批次飞机生产的考核已达到了预期效果,质量明显提高从而保证了飞机生产的进度和质量。
A machine cabin side lock parts made of GCr15 steel, the drawings require chrome plating, cracks and cracks are often found in parts grinding, magnetic particle inspection, chrome plating, before the assembly of parts, so the aircraft assembly progress and quality belt To the difficulties and hidden dangers, in order to improve the quality of parts production, to prevent the generation of cracks, the parts of the heat, the table processing technology was analyzed and verified and adopted a series of preventive measures to improve, through several batches of aircraft production has reached the assessment of the expected The result is that the quality is obviously improved so as to ensure the progress and quality of aircraft production.
