Cubic Boron Nitride (CBN)

CBN is excellent for the continuous cutting of a wide range of hardened steels, powdered metals, cast irons and super alloys. CBN tipped product are precision ground with hones for matching to sub-micron finishes with maximum tool life. CBN tipped tools and inserts can take the place of grinding.

Polycrystalline Boron Nitride (PCD)

PCD is excellent for continuous cutting of a wide range of non-ferrous and non-metal materials. The products are precision ground for machining to sub-micron finishes with maximum tool life. PCD tipped tools and inserts allow for higher cutting speeds with longer tool life.

Guidelines for CBN

(Ideal for hard ferrous metal -45 Rc plus)

Depth of cut should not exceed 30% of CBN tip length.
Do not use coolant as this could cause thermal cracking.
Do not stop the machine with the tool in cut - this will result in tool breakage.
Make sure the machine and setup is rigid and solid; chatter will cause chipping.
Tool height when boring should be slightly above center; tool deflection will put the tool on center.
Do not contact the tool to a hard surface prior to the machining process - this will cause chipping.

Guidelines for PCD

(Ideal for non-ferrous materials)

Higher speeds minimize tool buildup.
Depth of cut should not exceed 70% of PCD tip length.
Use of coolant will reduce heat and improve surface finish.
Do not stop the machine with the tool in cut - this will result in tool breakage.
Make sure the machine and setup is rigid and solid; chatter will cause chipping.
Tool height when boring should be slightly above center; tool deflection will put the tool on center.
Do not contact the tool to a hard surface prior to the machining process - this will cause chipping.

AS THE DOC DECREASES, THE FEED RATE CAN INCREASE

SCT CBN inserts are excellent for continuous cutting of a wide range of hardened steels, powdered metals, cast irons and super alloys. The inserts are precision ground with hones for machining to sub-micron finishes with maximum tool life. CBN tipped inserts can take the place of grinding.
