Machining method of ceramic guide rail with large size and wide end face

The invention belongs to the technical field of grinding processes of ceramic products, and particularly relates to a machining method of a large-size wide-end-face ceramic guide rail. The machining method of the ceramic guide rail with the large size and the wide end face comprises the following steps that the A face, the B face, the C face and the D face of a ceramic guide rail blank are machined in a plane grinding mode; the processed ceramic guide rail blank is fixed to a guide rail of a numerical control machining center in a horizontal fixing mode, and metering is conducted in the X direction, the Y direction and the Z direction of the ceramic guide rail; and the universal angle head is installed in a numerical control machining center, the dial A and the dial B on the universal angle head are utilized, machining is conducted in a layered machining and step-by-step progressive mode, and grinding of the wide end face of the ceramic guide rail blank is completed. According to the machining method for the
