Klemmvorrichtung für einen Schneideinsatz, und Schneideinsatz

摘要

There is disclosed a clamping mechanism for a cutting insert that clamps the cutting insert by inserting the cutting insert into an insert mounting seat. The insert mounting seat is formed in a tip of a holder 1 having a pair of contacting surfaces facing each other, and the cutting insert has a pair of contacted surfaces to come in contact with the pair of contacting surfaces, respectively. The tip of the holder is provided with a pair of jaws 3B and 3C that is formed with the pair of contacting surfaces, respectively, and that is capable of being elastically deformed relatively in a direction that the contacting surfaces come in contact with the contacted surfaces, and a clamping means 21 that elastically deforms the pair of jaws 3B and 3C to relatively bring the pair of contacting surfaces close to each other and to relatively separate them from each other.
