But the traditional ultrasonic machining method only can be used to drill hole and copy machining. It can't satisfy the need of modern machining because the structure of work is very complex and it need multi-axis harmonious motion to machine some complex surface. 但传统的超声加工只能进行一维加工,主要用于打孔和拷贝加工,已经不能满足现代生产的要求,因为现代生产中零件的结构越来越复杂,一些复杂曲面的成形往往需要几个运动精密的配合。
Ultrasonic detection of corrosions in the internal walls of oil drill rods 石油钻杆内壁体积型腐蚀缺陷的超声检测
The rotary ultrasonic machining is a new ultrasonic machining ( USM) method which has been mainly used to drill holes in hard and brittle materials such as ceramics, semiconductors, and glasses in recent years. 旋转超声波加工是一种新的超声波复合加工方法。近年来,它主要用于陶瓷、半导体和玻璃等硬脆材料的孔加工。
Firstly, expatiating the generally method of tube detection by ultrasonic, and then according to the particularity of the oil drill tube joins, we give out different methods to solve the problems. 第一部分首先阐述了超声波管材探伤的一般方法,然后结合石油钻杆接头的特殊性,逐步提出解决其探伤问题的特殊方法。
Ultrasonic detection of corrosions in the internal walls of oil drill rods is described including the principle, method and technology. 介绍石油钻杆内壁腐蚀缺陷超声检测的原理、方法及工艺,给出了实验结果。
