Reliability prediction of Centerless grinding machine

As recently optical communication industry is developed, request of optical communication part is increased. Ferrule is very important part which determines transmission efficiency and quality of information in the optical communication part. Most of ferrule processes are grinding which request high processing precision. The ultra precision centerless grinding machine for ferrule grinding was designed. The centerless grinding machine is composed of the high damping bed, grinding wheel spindle unit, regulating wheel spindle unit, feeding table and dressing unit. Reliability prediction was very important for the high quality design. In this study, centerless grinding machine was predicted reliability.
