利用超声波加工金属,可以降低切削热、提高工具耐用度、有利于切屑的形成和排除,并且在许多情现下尚可降低切削力。在苏联通常用于车、铣加工,美国则主要用于磨削加工与去除毛刺,新发展的有超声波珩磨。超声波磨削美国 Cavitron Ultrasonics 公司研究部门设计制成了“Ever-Grind”超声波磨头,其工作原理如图1所示:振动工具(振动头)1与砂轮6保持间隙≈0.13毫米。据云采用该超声波磨头加工时可以大大减少磨削热(与普通 The use of ultrasonic machining of metal can reduce cutting heat, improve tool life, facilitate chip formation and removal, and in many cases, reduce cutting forces. In the Soviet Union is usually used for cars, milling, the United States is mainly used for grinding and removal of burrs, the new development of ultrasonic honing. Ultrasonic grinding US Cavitron Ultrasonics research department designed the “Ever-Grind” ultrasonic grinding head, the working principle shown in Figure 1: Vibration tool (vibration head) 1 and the grinding wheel 6 to maintain the gap ≈ 0.13 mm. According to the cloud using the ultrasonic grinding process can greatly reduce the grinding heat (with ordinary
