y HONING AND LAND

Honing and land are cutting edge shapes that Honing Width Honing Width Land Width

maintain cutting edge strength. EDR Honing can be round or chamfer type. The Honing Angle

optimal honing or / and land width is

approximately 1/2 of the feed. Round Honing Chamfer Honing Flat Land

Land is the narrow flat area on the rake or flank face.

a Effects of Honing

1.Enlarging the honing increases cutting edge strength, and reduces fracturing. 2.Enlarging the honing increases flank wear occurrence. Honing size doesn't affect rake wear. 3.Enlarging the honing increases cutting resistance and chattering.
