Abstract
Abstract A high accuracy is obtained through adjustment of the cutting blades in the recesses housing them inside the cutter body, said adjustment being performed through a cam operated from the outside and acting on the blade which is held fast by a shim inside its recess, so as to deform it elastically and make it project to the desired extent beyond the cutter body. A support may be provided for the blade inside the recess.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
In a milling cutter comprising a body having at least one outward opening recess, said recess having an extension in said body, a cutting blade disposed in and projecting out of said recess, means in said recess clamping the blade fast between said clamping means and a side wall of the recess, and a hand-operable cam mounted for rotation in said extension and acting between said blade and a side wall of said extension to exert pressure on said blade; the improvement in which said cam has a rounded but noncircular cross section, said cam having line contact with said blade and with said extension wall along straight lines that are parallel to each other and to the axis of rotation of the cam and that are disposed on opposite sides of said axis, said lines being coextensive with each other, said cam along said lines having substantially constant cross sectional configuration.
Claim 2
Dependent Claim
