Exploration of Simplifying Grinding Process of Spindle Blade

为了解决锭杆传统加工工艺流程耗时长、用工多、报废量大等问题,分析用时最长的锭杆外圆磨削工艺的主要工作和难点,从工装改进、优化无心磨床磨削参数以及简化超精研工序进行探索。通过对比工艺简化后产品质量指标表明:改进后,锭杆加工工序简化5道,产品质量提升,设备占用率降低10%,整体产能提升超过30%,砂轮消耗降低约15%,托片使用寿命延长约15%;降低劳动强度,减少用工6~9人,达到预期效果;纺机专件加工工艺简化,要从全局出发,从细节处着手长期进行。

In order to solve the problems of the traditional processing process of spindle blade,such as long time consuming,more labor,and large scrap amount,the main work and difficulties of the external grinding process of spindle blade with the longest time are analyzed,and the improvement of the tool,optimization of the grinding parameters of the centerless grinder and simplification of the superfinishing process are explored.By comparing the process and simplifying product quality index,the results show that after improvement,the spindle blade processing is simplified by five passes,the product quality is improved,the equipment occupancy rate is reduced by 10%,the overall production capacity is increased by more than 30%,the grinding wheel consumption is reduced by about 15%,the service life of the bracket is extended by about 15%,the labor intensity is reduced,the number of workers is reduced by six to nine,and the expected effect is achieved.To simplify the processing of parts of the spinning machine,we should start from the overall situation and proceed from the details for a long time.
