Study on internal honing of small bore with ultrasonic vibration in the radial direction of honing stone

Abstract

To improve precision machining technology for small bore size, we examined the effects of honing stone grain size on the honing process using ultrasonic vibration in the radial direction of the honing stone as in-feed motion. In the honing of hardened steel, the size generation corresponded to the increase in vibration amplitude. Therefore, the finished size could be controlled by adjusting the vibration amplitude. In addition, the grain size effects of the honing stone on the size generation process and the honed surface properties in ultrasonic vibration honing were explored, yielding basic information on rational honing stone selection criteria.
