摘要
深孔的长径比(L/D)越大,钻削时加工难度也越大。为了提高深孔加工精度和工作效率,需要从刀具、工艺和控制等多方面加以改进。文章提出了一种基于伺服电机检测钻头扭矩、用PLC对加工过程进行自动控制、用人机屏实现人机交互的深孔钻加工系统。调试结果表明:采用该系统既能提高钻削效率和加工精度又能延长钻头的寿命。
The processing difficulty in drilling is increasing by the ratio of length to diameter of the deep-hole. In order to advance the machining accuracy and working efficiency, it is necessary to improve the drilling tool, manufacture technology and control method. A deep-hole drilling processing system is presented in this paper, using servo motor to measure the torque in time, implementing the automation controlling by PLC and human-computer interaction by man-machine interface. The result of debugging shows that this system can increase drilling efficiency and accuracy, and can decrease the damages of the bit.
