摘要:PROBLEM TO BE SOLVED: To restrain a phenomenon that slant cut is generated which is caused by inclination of a cutting blade, when a ceramic green block is to be cut by lever shearing by making the cutting blade act moving towards a table surface, in a state in which the ceramic green block is put on the table surface. SOLUTION: A slit 16, which is stretched parallel with a direction to which a blade tip of a cutting blade 15 stretches and whose center line is set on a position to which the blade tip of the cutting blade 15 advances, is formed on a table surface 13. By making stresses 17 in a ceramic green block forward 12 in the acting direction of the cutting blade 15, or by applying tension to the ceramic green block, the stresses in the ceramic green block is reduced, and stress in the ceramic green block 12 which is generated by lever-shearing of the cutting blade 15 acts evenly on both sides of the cutting blade 15.
