长期以来,某副箱产品因两次定位进行主轴承孔与中间轴孔,主轴承孔与台阶孔的加工,导致产品中心距与台阶孔深度等尺寸变动超差,产品报废率较高。为此,公司组织相关技术人员,跳出传统工艺思路,提出了对数控车床进行技术改造,将改造后的两台设备用于轴承孔与台阶孔的加工工艺方案。经过近3个月的使用验证,质量大幅度提高基本满足设计要求和批量化生产要求。
For a long time, the auxiliary box product has been machined twice for main bearing hole, middle shaft hole, main bearing hole and stepped hole because of twice positioning, resulting in the size variation of product center distance and step hole depth exceedingly and the product scrap rate is higher. To this end, the company organized technical personnel, out of the traditional ideas, put forward a CNC lathe for technological transformation, the transformation of the two devices for the bearing hole and step hole processing program. After nearly 3 months of use of certification, a substantial increase in quality to meet the basic design requirements and batch production requirements.
