Title:
TOOLHOLDER AND INSERT ARRANGEMENT WITH A SHRINK FIT COUPLING
Document Type and Number:
WIPO Patent Application WO2001045883
Kind Code:
A3
Abstract:
A toolholder and insert arrangement includes an insert having a cutting portion and a shank portion at a base of the cutting portion, and a toolholder having a first end attachable to a spindle and a second end having a shank-receiving opening. When the shank portion is not disposed in the shank receiving opening and the toolholder is at an ordinary room temperature, the shank-receiving opening is smaller than the shank portion, and 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 and, 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.
