超声波加工 meaning in English

supersonic machining
supersonic working
ultrasonic machining
ultrasonic working

However , traditional ultrasonic molding machining is in very low level at present . it adopts " principle of shape copy " , only be used in one dimension machining , and adjusts important machining pressure and feed technics parameters only by equipped weight , so the machining precision and machining efficiency are both very poor
从原理上讲，超声波加工是解决工程陶瓷加工难题最有潜力的技术之一，然而目前传统超声波成型加工处于十分落后的状态，它采用“形状拷贝原理” ，仅靠配重来调节加工压力和进给量等重要工艺参数，加工精度和加工效率都很低，而且只能用于一维加工中。
