重型油缸侧缸BTA深孔套料加工刀具过度磨损崩刃的研究

深孔加工的BTA套料工艺方式,工艺系统是处于内、外切削液和切屑包容的环境中,系统的任何微小外扰,都会造成系统的失稳,引起钻杆振动和刀具非正常磨损与崩刃。通过分析高精度、重型油缸侧缸的BTA深孔套料工艺,提出工艺系统失稳的解决措施,通过实际生产验证了措施的有效性。通过工艺优选试切试验,找出适合重型油缸深孔套料的一些加工参数,对生产中类似工件深孔工艺参数的选取具有参考价值。

Research on Excessive Chipping and Tool Wear for Machining Heavy Hydro-cylinder Based on BTA Deep Hole Trepanning

During the course of BTA deep hole trepanning processing,the processing system has been surrounded by internal and external cutting fluid and chip.BTA deep hole trepanning processing system should be induced instability by any small perturbations,including not normal chipping or tool excessive wear and vibration of drilling bar.The measures were proposed for solving the instability of BTA deep hole trepanning processing system,through analysis the high precision process of machining of heavy-duty hydro-cyli...
