Abstract
Milling cutter and method of operating same, and other machine tools, and an adjustment mechanism therefor. A cutting insert is adjusted by moving a resilient web with an adjusting screw.
Claims17
A tool holder for a cutting element, comprising:
- a tool base body;
- an insert seat for mounting a cutting element to the tool base body, the insert seat including a supporting face, at least one lateral bearing wall, and a rear bearing wall formed by a resiliently-held web;
- two front cutting elements configured to enlarge a diameter of a hole to a desired thickness, and two rear cutting elements configured to further enlarge the diameter of the hole formed by the two front cutting inserts;
- an expanding slot including a longitudinal leg and a transverse leg extending substantially perpendicular to the longitudinal leg to connect the longitudinal leg with the insert seat;
- and
- an adjusting screw for adjusting a radial position of the cutting element, the adjusting screw capable of being received in a tapped hole, the tapped hole intersecting the expanding slot such that rotation of the adjusting screw in the tapped hole causes the resiliently-held web to move radially outward, thereby effecting fine adjustment of the cutting element in a radial direction.
