QT700-10球墨铸铁具有良好的减振性和自润滑功能,抗压和抗拉能力强于灰铸铁,但是QT700-10的塑形和韧性比钢低很多,可加工性不高。为了研究QT700-10的钻削力和加工质量,设计正交试验,使用硬质合金钨钢涂层钻头钻削QT700-10工件。利用极... QT700-10球墨铸铁具有良好的减振性和自润滑功能,抗压和抗拉能力强于灰铸铁,但是QT700-10的塑形和韧性比钢低很多,可加工性不高。为了研究QT700-10的钻削力和加工质量,设计正交试验,使用硬质合金钨钢涂层钻头钻削QT700-10工件。利用极差分析方法,对钻削合力及孔圆度误差进行影响因素评价。影响钻削合力的因素依次为每齿进给量>钻头直径>主轴转速;影响孔圆度误差的因素依次为每齿进给量>主轴转速>钻头直径。钻头的主要磨损形式是黏结磨损,10mm钻头的磨损宽度最大。综合考虑钻削合力、孔圆度误差和钻头磨损后,提出QT700-10的钻削加工关键参数组合为:钻头直径为8mm,主轴转速为3000r/min,每齿进给量为0.18mm/r。 展开更多

The thrust and the torque of various carbide drills are studied for the high-speed drilling of fiber reinforced epoxy composites. The orthogonal experiment is carried out with different feed speeds at high rotation speed. Experimental results show that the spindle rotation speed is the most influential factor. The thrust andthe torque decrease under the condition of high rotation rate. With the decrease of the feed speed, the thrust and the torque decrease. But the effect of the feed speed is less than that of the spindle rotation rate. Moreover, the effect of drill materials on the thrust and the torque is more notable than that of the drill geometries and the feed speed. The thrust is greatly affected by the feed speed while the torque is obviously affected by drill geometries. 展开更多
