Ultrasoniion is an efficient means for the wetmilling and microgrinding of particles. Besides dispersing and deagglomerating, the wet milling is an important appliion of Hielscher ultrasonic devices.. In particular for the manufacturing of superfinesize slurries, ultrasound has many advantages, when compared with common size reduction equipment, such as: colloid mills ( ball mills ...
· The integrality of edges has a significant impact on the final form accuracy of ground microstructured surfaces. Therefore, the effects of ultrasonic vibration and tilt angle on the microstructured edges were also investigated. Fig. 5 shows edge morphologies of micro cylinder arrays machined by UVAG and conventional grinding. In the conventional grinding without vibration, although few ...

In case of xdirection (tangential direction of grinding wheel) ultrasonic vibration, abrasive grains with periodic force impact material surface with high frequency vibration, which make material fracture removal easy. Therefore, the high efficiency essence of material removal in twodimensional ultrasonic grinding is revealed in view of locus. In addition, according to the results of ...
· As can be seen from Figure 10, in ultrasonic grinding when grinding depth a p = 20 µm, at the bottom of the groove is wide and smooth, narrow groove width, edge was gnawing gap, good heat dissipation, no burn phenomenon. This is due to the impact of the ultrasonic vibration. During the grinding process, the abrasive grains have a strong impact on the material to be processed, and a .
ordinary grinding) while maintaining low machining pressure and less surface damage [3, 4]. With extensive use of ultrasonic assisted machining ( ultrasonic vibration grinding and ultrasonic vibration filing [5, 6]), it is essential to do indepth study on the performance of transmission circuit.
