摘　　要：研制了内排屑深孔钻削-滚压复合加工实验装置,并初步探索了提高深孔加工效率的新工艺。该实验装置主要包括深孔钻削-滚压加工系统和切削液供给系统,前者由钻削-滚压复合工具、旋转式授油器和钻杆夹持器组成,后者由齿轮泵及压力控制系统组成。对45钢进行深孔钻削实验,详细观测并分析转速和进给量对切屑厚度和切屑形态的影响。结果表明,与转速相比,进给量对切屑形态及厚度的影响更大,切屑形态随进给量增加发生显著变化;调整工艺参数形成C形切屑时钻削过程顺畅。该装置用于实践教学,可加深学生对内排屑深孔加工方法及原理的理解。A set of teaching experimental device of internal chip removal deep hole drilling-rolling compound processing is developed and a new process for improving machining efficiency is preliminarily explored.The experimental device consists of a deep hole drilling-rolling processing system,which consists of a drilling-rolling compound tool,a rotary oiler and a drill pipe holder,and a cutting fluid supply system,which consists of a gear pump and a pressure control system.The deep hole drilling experiments on 45 steel are carried out to analyze the effects of rotary speed,feed rate on chip thickness,and chip shape.The results show that the chip morphology changes significantly with the feed rate.The drilling process is smooth when the process parameters adjusted to form c-shaped chips.Through practice teaching,the students’understanding of deep hole processing method of internal chip removal is deepened.
