On the basis of analyzing the shortcomings of the traditional process of ceramic materials,according to the requirements of users,for the ceramic material conveyor roller with high brittleness and difficult processing,the multi-saw blade rotary cutting program was proposed to ensure that both ends of the plane parallelism,yield and processing efficiency.For Al2O3 ceramic roller,a special sawing machine was designed.The overall structure of the special sawing,and peeling program,design of saw blade replacement mechanism and support seat,calculation of cutting force and power,work process were introduced in detail.
