Honing and land are cutting edge shapes that maintain cutting edge strength. Honing can be round or chamfer type. The optimal honing width is approximately 1 2 of the feed. Land is the narrow flat area on the rake or flank face.

Enlarging the honing increases cutting edge strength tool life and reduces fracturing. 2. Enlarging the honing increases flank wear occurrence and shortens tool life. Honing size doesn't affect rake wear. 3. Enlarging the honing increases cutting resistance and chattering. When to Decrease Honing Size O When finishing with small depth of cut and small feed. O Soft workpieces. O When the workpiece or the machine have poor rigidity. When to Increase Honing Size O Hard workpieces. O When the cutting edge strength is required such as for uncut surfaces and interrupted cutting. O When the machine has high rigidity. Cemented carbide coated diamond and indexable cermet inserts have round honing as standard. Q009 TECHNICAL DATA HONING AND LAND
