WERKZEUGHALTER UND SCHNEIDEINSATZANORDNUNG MIT EINER SCHRUMPFSITZKUPPLUNG |
摘要 |
A toolholder and insert arrangement includes an insert having a cutting portion and a shank portion disposed at a base of the cutting portion. The toolholder has a first end attachable to a spindle and a second end having a shank-receiving opening. When the toolholder is at ordinary room temperature, the shank-receiving opening is smaller than the shank portion. Upon heating of the toolholder to a predetermined temperature above the ordinary room temperature and above an ordinary operating temperature, the shank-receiving opening expands to become at least as large as the shank portion. Upon cooling of the toolholder to a temperature below the predetermined temperature and after insertion of the shank portion in the shank-receiving opening, the shank-receiving opening shrinks to generally conform to a shape of the shank portion. |
