CUTTING HEAD FOR ROTARY CUTTING TOOL Russian patent published in 2009 - IPC B23B29/34 

FIELD: mechanics, tools.

SUBSTANCE: proposed cutting head is designed to be mounted with shift on shank for metal cutting. It has axis of rotation and incorporates casing with recess to house insert, recess being confined by base and three lateral walls passing axially along normal to the base. Two lateral walls are arranged in parallel, the adjacent lateral walls being arranged perpendicular to each other. The insert is integral element with upper and lower opposite and parallel surfaces, as well as peripheral lateral surface arranged between above surfaces. Slot passes between two opposite lateral parts of the peripheral lateral surface, from the upper to lower surfaces, to separate the insert into clamping and main parts. The clamping part has flexible coupling with the main part. The cutting plate clamping seat represents a slot widening on section open towards the upper surface side. The cutting plate is fixed in seat between the main and clamping parts.

EFFECT: higher rigidity, stable position of cutting plate.
