As one of leaders of Modern Grinding Process Technology Pdf industry, SBM always seeks innovation & excellence.
Ultrasonic machining, or strictly speaking the "Ultrasonic vibration machining", is a subtraction manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. The tool travels vertically or orthogonal to the surface of the part at amplitudes of 0.05 to 0 ...

Significant progress has been made in the past 50 years in advancing our understanding of the complicated and seemingly random process of grinding, moving it from a sort of black art to an understandable chip-formation process. These advances have been successfully exploited by grain manufacturers, wheel manufacturers and grinding-machine manufacturers in improving their products.

However, at the same time it must be noted that it is more appropriate to link grinding to a finishing process rather than a manufacturing process, in the true sense of the word, though these terms are used alternatively in common usage. Apart from being used as material removal process, it is also used to sharpen the cutting edges of cutting tools and sharp objects such as knives, although ...
