一、深孔加工钻杆振动原因分析在深孔加工过程中，由于钻杆的细长特征，其振动常成为影响加工精度、刀具耐用度和切削效率的主要因素。钻杆系统的振动主要包括钻杆的弯曲振动和扭转振动两个方面。形成钻杆弯曲振动的主要原因是：钻削长径比较大的深孔时，钻杆相对比较细长，相 A Deep Hole Drilling Rod Vibration Analysis Deep hole machining process, due to the slender features of the drill pipe, the vibration often become a major factor affecting the machining accuracy, tool durability and cutting efficiency. The vibration of the drill pipe system mainly includes the bending vibration and the torsional vibration of the drill pipe. The main reason for the formation of the bending vibration of the drill pipe is as follows: when drilling the deep hole with larger aspect ratio, the drill pipe is relatively slender,
