A New Ultrasonic Honing Device with Ultra-Precision

The embedded transducer structure is used to put the transducer into the inside of the honing oil stone bed, which is directly driven by the transducer to vibrate and carry out the ultrasonic honing. Experiments show that honing efficiency of the device lowers by 50%, the roughness of honing surface Ra reaches 60nm - 30nm and the cylindricity comes to 10μm - 1μm, which is much higher than the traditional ultrasonic honing precision. This method solves a range of issues of complex structure, high manufacturing costs, not suitable for ultra-precise honing of the traditional ultrasonic honing head, and it is simple to process and easy to install with low manufacturing costs. Because there is no amplifying of horn, the amplitude is very small, which is especially suitable for ultra-precision honing.
