DEVICE FOR CLAMPING A CUTTING INSERT TO A SEAT OF A TOOLHOLDER BODY

摘要

A device for clamping a cutting insert to a seat of a toolholder body, said seat having a supporting and a pair of transversely oriented holding surfaces against which the insert is firmly wedged during the threaded engagement of a clamp screw in an inclined threaded opening in the toolholder seat. The inclination of the threaded opening is such as to produce the desired wedging effect against one holding surface during rotative or tightening manipulation of the screw, while said rotative screw movement produces the wedging effect against the other transverse holding surface.
