Research on Ultrasonic Honing Performance of ZrO_2 Engineering Ceramics Using Diamond Oil-stone with Coarse Grains

摘要

The experiments of common and ultrasonic honing ZrO_2 engineering ceramics using diamond oil-stone with coarse grains were carried out in this paper. The influences of grinding depth and rotative velocity of principal axis on surface reduction ratio, temperature of grinding zone, grinding force and surface roughness were clarified. The transformation characteristic from ductile region to fragmenting region, temperature characteristic of grinding zone, grinding force characteristic and the quality of machined surface in two kinds of honing modes were further studied. The research results indicate that ultrasonic honing not only possesses wider ductile grinding region, lower temperature of grinding zone and smaller grinding force but also can obtain higher surface quality compared with common honing.
