SUMIBORON® CBN
■ General Features Sintered CBN - SUMIBORON ® , which has CBN (cubic boron nitride) is a hard material second only to diamond - as its main component. CBN is sintered with a special ceramic binder under ultra-high pressure and temperature. CBN - SUMIBORON ® has high hardness, excellent thermal resistance and excellent properties including being unreactive to ferrous metals, enabling exotic alloys, hardened steel or hard cast iron to be machined. Excellent efficiency and longer tool life can also be achieved from high-speed finishing of cast iron. Sumitomo's CBN - SUMIBORON ® was first successfully developed in Japan by our company in 1977. Coated CBN - SUMIBORON ® with a special ceramic coating, and binderless CBN made by directly bonding CBN particles without a binder are new additions to our product lineup.
L
Sintered CBN - SUMIBORON ® is mainly used for the machining of ferrous metals due to its low chemical reactivity with iron. There are 4 different classifications of CBN -SUMIBORON ® as follows:

HARDENED STEEL MACHINING
● Advantages of CBN - SUMIBORON for hardened steel cutting Below is an analysis of the use of CBN compared to grinding. In terms of cost, not only is the investment involved for introducing new machinery reduced, it is possible to shorten the processing cycle time by finishing complicated shapes in one run. In terms of quality, machining with a single chuck is possible, improving machining accuracy and squareness. Furthermore, dry machining is possible, with various advantages such as better global environmental conservation and resource recycling. The workpieces shown in the table to the lower right have shapes more likely to benefit from being cut, especially compared to grinding.

SINTERED COMPONENT MACHINING
● Advantages of cutting sintered components with CBN - SUMIBORON CBN - SUMIBORON has much smaller edge wear than carbide or cermet, and also has better wear resistance and can form a sharp edge easily. CBN - SUMIBORON is able to prevent burrs and chipping on the edges of the workpiece, achieving good machining precision and surface roughness.

Cutting Speed v C (SFM)
For general powdered metal, carbide and cermet grades can perform up to v c = 330 SFM. However, around v c =400 SFM, wear becomes rapid and surface roughness deteriorates with increased burrs. On the other hand, CBN (SUMIBORON) exhibits stability and superior wear resistance, burr prevention and surface roughness, especially at high speeds.
