Abstract：This processing task of large-diameter，ultra-long and thin-wall cylinder of a product undertaken by the company cannot meet the requirements of drawings by conventional turning and milling methods.Based on the existing equipment conditions of the company，the research on CNC turning of large diameter，ultra-long and thin-wall barrel，large diameter and deep-hole boring and CNC bench slotting was carried out，which solved the problems of dimensional accuracy and form tolerance of large diameter，ultra-long and thin-wall barrel that could not meet the technical requirements.

Key words：large diameter;ultra-long and thin-wall cylinder slot;processing deformation;clamping
