Insert holder having adjustable insert seat plate

摘要

An insert holder includes a head having ridge teeth, and an insert seat plate seated on the head such that ridge teeth thereof mesh with the ridge teeth of the head. The plate forms a V-shaped recess in which a cutting insert is to be received. The recess thus defines a position of support for the insert. A bisector of the V-shaped recess extends parallel to the ridge teeth. The insert seat plate is adjustable in the direction of the bisector (e.g., by individually deployable spacer plates of different thickness) to adjust the position of support defined by the V-shaped recess.
