Ceramic roller is more reliable than metal roller. However, ceramic materials are difficult to process due to their high hardness and great brittleness. They are easy to crack and easy to damage cutting tools. To batch processing of ceramic roller blanks (CRBs), a special ceramic roller cutting equipment (SCRCE) is designed to deal with CRBs of different diameters and lengths. To avoid clamping damage to CRBs, the SCRCE adopts the new clamping mechanism. The blanks are orientated to double rotating shafts with V-type sleeves to reduce friction. Moreover, the SCRCE adopts a new ring-cut method. The ring-shape cutting is used. The cutting spindle and the blanks are revolving at the same time in cutting processing. The design and modelling of the special cutting equipment is also finished. To analysis the axial displacement of CRBs while cutting, the simulation model with ADAMS is built and the related characteristic is simulated. The test result shows that the new type cutting machine is suitable for ceramic roller blank cutting process.
