Title:
MILLING CUTTING TOOL EMPLOYING A CUTTING INSERT
Document Type and Number:
WIPO Patent Application WO/2010/079948
Kind Code:
A2
Abstract:
The present invention relates to a milling cutting tool employing a cutting insert. More specifically, the invention relates to a milling cutting tool employing a cutting insert which can increase the life of the tool because of the formation of concave, nick cutting edges in the side surfaces of the cutting insert and the consequent action whereby chips are finely sliced, the effective machining cutting edge is shrunk, friction is reduced and cutting resistance is reduced during high incision; and which can improve productivity because chip discharge is facilitated and resistance is reduced such that, consequently, a relatively large amount of travel can be achieved during high incision; and which can reduce the cutting resistance between the upper and lower surfaces and the chip sliced fine by means of the concave, nick cutting edges, because concave recesses are formed in the upper and lower surfaces of the cutting insert; and which further can perform a nick cutting edge function even without deformation of the seat side surface of a seat part for fastening the cutting insert and the cutter body, because a concave nick cutting edge is formed in the main cutting edge of the cutting insert.
