To shaft component with cylindricity tolerance requirement, processing benchmark unity must be guaranteed in the machining process.If there were many times benchmark changing phenomena caused by component structure, process chuck could be reserved and added to guarantee both ends benchmark unity. It provides convenient for the followup grinding processing and guarantee component cylindricity.
