摘要
光学玻璃的脆性较大、硬度大以及强度高,在传统孔加工中极易产生边缘破损。本文设计了超声纵扭振动钻削装置,采用上压板与下支撑板的新装夹方式,给出了孔口崩边程度的评价指标。试验结果表明,当转速为4500r/min、振幅为6μm、进给速度为3mm/min时,孔口加工质量较高。
Optical glass has large brittleness, high hardness and high strength, the edge-chipping generates easily in the traditional drilling method. In this paper longitudinal-torsional composite ultrasonic vibration drilling device was designed, introduce new clamping method grouped by pressing plate and support plate, and the evaluation indicators of orificesedge-breakingweregiven. The experiment results show that when the rotational speed is 4000 r/min, the amplitude is 6μm and the feed speed is 4 mm/min, orifice machining quality will be better.
