摘要 |
<p>Provided is a deep hole cutting apparatus having a chip-replaceable guide pad on a cutting head section. With the deep hole cutting apparatus, high machining accuracy can be obtained in a stable cutting status and the service life of the guide pad is lengthened. A guide pad (7) is formed on a circular surface (71a) whose outer surface forms a top ridge section (7a) along the center portion in the width direction, and the guide pad is diagonally attached to a cutting head section (10a) so that the leading end side of the tool is closer to the front side in a tool rotating direction (y) compared with the rear end side of the tool.</p> |
