The Cutting Method of Ceramic Plates Make Use of Spherical Surface

A cutting method for ceramic plate is proposed. This method is an application of the fracture of brittle materials under bending moment. Bending moment arise from compressive lode applied to the ceramic plate put between a concave and convex spherical surface. Then the ceramic plate is cut along the...

Summary:A cutting method for ceramic plate is proposed. This method is an application of the fracture of brittle materials under bending moment. Bending moment arise from compressive lode applied to the ceramic plate put between a concave and convex spherical surface. Then the ceramic plate is cut along the notches of desired shapes on one surface. The characteristics of the cutting method are: (1) Cutting can be carried out without dust, and the cutting sections are smooth. (2) The ceramic plate can be divided into many equal parts and cut simultaneously in square and traiangylar shapes during one compression. (3) Ceramic plate can be easily cut along various shapes such a curve and a circle. (4) This method can be cut a number of plates, almost instantly.
