CBN steel is fabricated in hardness only with diamonds, still providing high wear resistance to Carbide in some applications. North American Carbide offers more than 20 CBN scores, allowing us to find the perfect solution depending on your use. Both induction and vacuum brazing are available.

3 Your Work Ways Cost Cbn Tooling

Whether you are using mini-tapes, large tapes, individual tapes, double tapes, triple or solid, North American Carbide will have the ability to recycle your items and save you money.

Relapping Insets:

  • This is the easiest and least expensive way to reset your CBN devices. The wear on your placement is measured and we simply grind back your cut to clean the dressing. Edge preps, if any, are used again and you return the cutting tool at a fraction of the cost of a new one. This installation can be used in its original design.
  •  Resetting Insert:
  • In this process, the wear on your input is measured and a field of equal or larger size is placed behind the insertion tape. The original geometry of your device then goes back and forth giving you as a new cutting edge.

Retipping Insets:

In this process, we simply remove the used lip from its carbon footprint. The new tip is returned to the device saving you the cost of replacing the body.

Manufacturing Dry Steel With CBN Insets

Hard metal fabrication is the most preferred type for CBN inserts because, at hard above 50-55 HRC, it is the only solution that works without grinding. Despite its high price, it is still the most economical response to these requests.


  • Excellent wear resistance.
  • Length of use-life
  • High cutting speed
  • Maintaining close patience.
  • The end of the upper extremity
  •  It can replace digestion in many applications.

That’s bad:

  • The price is high.
  • Depth of cutting edge. The depth of cutting is limited by the size of the brazed CBN tapes.
  • solid cbn inserts manufacturers which enable heavy machining is very expensive.

Are there fewer and faster CDs and CBN installs?

Contrary to many assumptions, PCD has a wide range of SFM aluminum alloys, ranging from as low as 200 to 6,000, and will consume carbide deposits at least 10x, allowing the tools to remain in endurance without compromising long-term cutting time. With the introduction of CBN, feeds as low as 200 SFM are commonly used in metal drying.

With our boring tools, it is often necessary to consider the tool assembly and workpiece to set the stiffness while performing the step towards high-speed machining with these types of inserts. Typically, a boring head with built-in counter-mounting counterweights will be required to be able to run the speed at which these inserts are capable.

What is the main difference between PCD and CBN sets?

PCD inserts are the first choice in aluminum and magnesium application, as well as carbon fiber components, as its high hardness gives unparalleled life in these non-ferrous materials. As a synthetic diamond (almost pure carbon), it cannot be used to make ferrous materials such as steel and cast iron, because at temperatures above 700 ° Fahrenheit carbon atoms form part of the material to form iron carbide and make diamonds. decay. PCD is especially popular if aluminum has more than 5 percent of the interior, to combat abrasiveness leading to wear.

CBN uses boron as a primary substance. Although boron has a carbon-like crystal structure, it lacks affinity for iron. It is the second hardest known material and can withstand cutting temperatures above 1,800 ° Fahrenheit. CBN is suitable for steel or steel machining and is the first choice when working with hardened metals, usually more than RC50, and should only be used for finishing. Any cutting error requires a very stable tool, otherwise, it will not work.

CBN comes in different grades, where bands such as ceramics and metal are added to change patterns. The grain size of the crystal structure can also be adjusted to other patterns. High CBN inner core with ultrafine grain size is the hardest mixture, suitable for continuous machining of hardened cast iron and powdered metals. Our grade CBN-CH, however, is only gray cast iron and should not be used to drain ductile or chilled iron, it will not give the device a longer life than traditional carbide grades.

CBN inserts can also be closed intermediate-grain size CBN material with TiCN coating is recommended for the manufacture of solid metals.
