edge conditions available WITH ILPT PCBN range
Cutting + - Edge Forces Strength
S-Land
( CHAMFER + HONE )
Best choice for hard part turning & generates consis- tent surface finish.
Stronger edge than T-land, with more resistance to chipping & fracture, resulting in more predictable tool life.
Critical in interrupted cutting and when using a large depth of cut and the feed rate must be greater than hone size.
T-Land ( CHAMFER )
T- land is a common edge preparation for PCBN.
A preferred choice for cast iron.
A good alternative to S-land in hard part turning when reduced cutting forces and tighter tolerances are required.
E-Land ( EDGE HONE )
Honing helps strengthen the edge, giving resistance to chipping and fracturing.
Feed rates must be greater than the hone size to allow actual cutting action to take place and prevent rubbing.
