摘要
针对可加工陶瓷在冷加工过程中由于材料脆性大产生的崩角、裂纹质量问题,以及为实现产品精度采用低转速和小进刀量加工导致的效率低,在理论分析的基础上,优选了数控铣磨工艺方法,并从刀具选用、参数控制等方面完成了技术探索及试验。以某型号重点产品薄壁陶瓷骨架为验证对象,以精密数控铣磨的方法代替传统铣加工,产品合格率由70%提升至95%以上,生产效率提升至100%。
Aiming at the problem that the machinable ceramics are easy to produce corner cracks due to large brittleness of materials in the cold machining process,and the low efficiency due to low speed and small feed machining are adopted for products accuracy,this paper explores the research on precision milling and grinding technology.The analysis and test are completed in the aspects of theoretical analysis,tooling design,tool selection,and parameter control.The thin-walled ceramic skeleton of a key product of a certain model is taken as the verification object,and the method of precision NC iron grinding is used to replace the traditional iron processing.The qualified rate of products is increased by more than 95%from 70%,and the production efficiency is increased by 100%.
