FIELD: process engineering.
SUBSTANCE: cutting plate is intended for milling tool, particularly, face mill and has cutting edges arranged on opposite sides. Note here that cutting edges extend beyond adjacent cutting surfaces directed downward at positive front angle where between one or several flat support surfaces are located as well as central fastening hole to receive tightening screw. To increase cutting plate efficiency, at least, one truncated-cone-shaped face is arranged around said central hole. Note here that said face tapers off radially inward indirection of said fastening hole.
EFFECT: higher efficiency and quality.
