Abstract
The present invention provides a cutting method of a ceramic honeycomb formed body for cutting the ceramic honeycomb formed body with a fine line stretched at an appropriate tension substantially at right angles to the direction of throughholes thereof. The method comprises the steps of providing a cutting guide groove running through the outer periphery of the ceramic honeycomb formed body substantially at right angles to the direction of throughholes , and putting a fine line to the cutting guide groove , to cut the ceramic honeycomb formed body only by pressing the fine line against the ceramic honeycomb formed body . By using this cutting method, it is possible to cut a ceramic honeycomb formed body having thin partition walls of under 125 &mgr;m without causing a distortion. The possibility to reduce the cutting frequency of the fine line leads to possibility to improve the cutting efficiency.
