|20130336735||CUTTING INSERT - A cutting insert, and more particularly, an improved double-sided cutting insert is provided, which provides improved machinability obtained due to increased rake angle, without compromising coupling state. The double-sided cutting insert includes a top surface, a bottom surface, a plurality of lateral relief surfaces connecting the top and bottom surfaces, and a cutting edge formed by the top and bottom surfaces and the plurality of lateral relief surfaces, in which one or more lateral relief surfaces of the plurality of lateral relief surfaces are formed into three stages in sequence which are a first positive surface, a negative surface and a second positive surface in a direction from the top surface to the bottom surface.||12-19-2013|
|20130149527||COATING LAYER FOR CUTTING TOOLS - Provided is a coating layer for cutting tools, as a hard coating layer stacked and formed in the sequence of a TiN layer, a TiCN layer, a bonding layer, an alumina (Al||06-13-2013|
|20120170986||DOUBLE-SIDED CUTTING INSERT - A double-sided cutting insert includes: rectangular shaped upper and lower surfaces formed at upper and lower sides of the insert; four side surfaces of each of the upper and lower surfaces; an assembling hole perpendicular to the upper surface; major cutting edges, at corners of one side surface, and rotationally symmetrical with respect to a center of an outer shape of the insert in a plan view where the upper surface is the front and rotationally symmetrical with respect to the center in a front view where the one of the side surfaces is the front; minor cutting edges, formed at one side of each major cutting edge, and rotationally symmetrical with respect to the center in the plan view; and minor side surfaces formed on a surface where the minor cutting edges meet the side surfaces and inclined toward the center with respect to an assembling hole central axis.||07-05-2012|
|20110033723||MULTI-LAYER HARD FILE FOR INDEXABLE INSERT - The present invention discloses a multi-layer hard film for an indexable insert. The multi-layer hard film for the indexable insert provided by the present invention is formed by sequentially depositing a base layer, an intermediate layer and a top layer with different composition ratios and film structures individually on the indexable insert, thus minimizing a delamination and tool wear which may occur in high speed machining.||02-10-2011|
|20100054872||MULTI FUNCTION CUTTING TOOL - A multi-function cutting tool is disclosed. The multi-function cutting tool includes a cutting insert (||03-04-2010|
