PROBLEM TO BE SOLVED: To provide a cutting method for a hollow porous body, for precisely cutting a workpiece composed of a hollow porous body as a collective body of hollow column-shaped cells with good yield in cutting and at high efficiency. SOLUTION: In a method for cutting a workpiece composed of a hollow porous body as a collective body of hollow column-shaped cells, hard foamed plastic materials or solid materials can be molten at the low temperature are filled in a cavity part of a machining part of a hollow porous workpiece, and the workpiece is cut by a cutting means provided with a blade part to which abrasive grains harder than the machining part of the hollow porous body, having the side in the range of 0.1 to 0.5μm, and composed of at least one or more kinds of diamond abrasive grains, alumina abrasive grains, silicon carbide abrasive grains, and CBN abrasive grains are stuck. |
