| 发明名称 | Cutting method of honeycomb formed body | ||
| 摘要 | A cutting method of a honeycomb formed body is provided. This is a cutting method of a honeycomb formed body in which, while a kneaded material containing a ceramic raw material is extruded to form a honeycomb formed body with a honeycomb shape having partition walls defining and forming a plurality of cells, the extruded honeycomb formed body is cut before drying by a cutting blade vibrated at a frequency of 0.3 kHz or more in a direction perpendicular to a direction in which this honeycomb formed body moves. It is preferably a cutting method of a honeycomb formed body in which the cutting blade is vibrated at a high frequency of 10 kHz or more. | ||

| 主权项 | 1. A cutting method of a honeycomb formed body, wherein, while a kneaded material containing a ceramic raw material is extruded to form a honeycomb formed body having partition walls defining and forming a plurality of cells and having a honeycomb shape, the extruded honeycomb formed body is cut before drying by a single cutting blade vibrated at a frequency of 0.3 kHz or more in a direction perpendicular to a direction in which the honeycomb formed body moves, wherein an extrusion speed of the honeycomb formed body and a component of the moving speed of the cutting blade in a direction in parallel with a direction in which the cells of the honeycomb formed body extend are equal. | ||
