Description
 
Ultrasonic processing is a special processing that uses ultrasonic frequency to make small amplitude vibration tools, and through the impact of the abrasive free in the liquid between it and the workpiece on the surface to be processed, the surface of the workpiece material is gradually broken. Ultrasonic machining is often used for piercing, cutting, welding, nesting and polishing.
Ultrasonic vibration cutting is a kind of pulse cutting microscopically. In a vibration cycle, the effective cutting time is very short, and it is completely separated from the workpiece and the chips for more than 80% of the time. The intermittent contact with the workpiece and the chips reduces the friction, the heat generated is greatly reduced, and the cutting force is significantly reduced, which avoids the "knife" phenomenon in ordinary cutting, and does not produce built-up edge. Using this kind of vibration cutting, precision machining can be performed on ordinary machine tools. The geometric tolerances such as roundness, cylindricity, flatness, parallelism, straightness, etc. mainly depend on the accuracy of the machine tool spindle and guide rail, and can reach nearly zero error. It is possible to replace grinding by car, reaming by drilling, and grinding by milling. Compared with high-speed hard cutting, it does not require high machine tool rigidity and does not damage the metallographic structure of the workpiece surface. In the finish machining of curved contour parts, it is possible to use CNC lathes, machining centers, etc. for profiling machining, which can save the expensive purchase cost of CNC grinding machines.
 
Brief introduction
1 The cutting force is small, about 1/3-1/10 of the ordinary cutting force.
2 The machining accuracy is high, which mainly depends on the accuracy of the machine tool used, and the shape and position tolerance of the processed workpiece can almost be close to the relevant accuracy of the machine tool.
3 The cutting temperature is low, and the workpiece is kept at room temperature.
4 There is no built-up edge, small deformation of the workpiece, and no burrs.
