Abstract: Vibration disk has certain influence on the resonance frequency of ultrasonic honing vibration system when ultrasonic honing device is designed. The results of theoretical calculation are basically conformed to that of experiments, which have been investigated by means of experimental and theoretical calculation method. This study provides a basis for the development of ultrasonic honing device. Undergoing practice we can find that the efficiency ultrasonic honing system as above described can be extended and applied to production. The system is a typical non-conventional machining, but it can be applied not only to conventional honing machine , its technology effect as good as high precision machine tool , but also to developing and studying ultrasonic vibrating numerical controlling honing machine tool which will provide a new type, efficient, high quality low consumption, equipment for working precision hole.

Abstract: Green machining fluids of oil-filmed water-droplets (OW) can be produced by means of combined mist-jet with cooled air, minimum naturally dissoluble oils (botanic or ester oils) and little water, which are beneficial to realize zero-emission machining and thoroughly eliminate the influences of the conventional water-miscible machining fluids on the operators’ health and the eco-environments as well as save energy consumption and lower in production costs. In this study, grinding performances and mechanism analyses of green machining fluids are investigated by comparison to the conventional ones such as emulsion flood coolant on the plane NC grinder. The investigations have further shown that green machining fluids can improve grinding quality in comparison with emulsion flood coolant due to good lubrication and cooling effects, which are applicable to many situations of machining processes.
