<p>A throw-away tip capable of eliminating such a problem associated with a conventional small-sized ultra high pressure sintered throw-away tip that it is troublesome to install the tip in a holder due to absence of a hole or a recess for mounting in the holder and a tightening force was also weak because the hardness of an ultra high-pressure sintered body was high and the processing of the surface thereof was very difficult, wherein a recess for mounting in the holder is provided in the face of a throw-away tip formed of an ultra high-pressure sintered body by processing the tip while adjusting the output of a laser beam, increasing a condensing degree by a galvanometer mirror, and controlling a radiating position with high accuracy, whereby the small-sized ultra high-pressure sintered throw-away tip can be easily and surely installed in the holder with a clamp, a setup time can be shortened, a processing accuracy can be increased, and reliability of installation can be increased.</p> |
