CBN/PCD TOOLS
SUMIBORON series
New generation Sumiboron inserts – an even better way to machine hardened steels
Building on its global success machining hardened steels with Sumiboron inserts the addition of heat and wear resistant coatings to a variety of tough new CBN substrates has resulted in a new generation of high performance grades. With economy in mind the new inserts are multi cornered.
Choose the coated insert suitable for your application and take your hard part machining operations to the new industry standard. The sintered CBN tool SUMIBORON is mainly used for the machining of ferrous metals due to its low chemical reactivity with iron.
New Coated SUMIBORON Series achieving
– higher speed
– higher efficiency and
– higher precision
Using a high heat resistant and tough CBN substrate coupled with a special ceramic coating, this series caters to a wide variety of applications with improved precision and longer tool life as compared to conventional CBN. There is a comprehensive lineup of economical and easy-to-use insert selection, such as the cost effective double-sided, multi-cornered, one-use type inserts.

Hardened Steel Machining
Advantages of Using CBN
In terms of cost investment, it is much lower in machine cost and overhead cost due to the fact that a CNC lathe is cheaper than a grinding machine. As for the quality of finish, inserts can machine different profiles and the finishing is also commendable as compared to grinding. Environmentally, sludge treatment for grinding is a hazard to the environment but for turning, the chips can be collected and recycled.
Sintered Component Machining
Advantages
SUMIBORON has much smaller edge wear than cemented carbide or cermet. It also has better wear resistance and can form a shape edge easily. SUMIBORON is able to prevent burrs and chipping on the edges of the workpiece, achieving good machined precision and surface roughness.
Roll Machining
Advantages
SUMIBORON enables the machining of high-hardness rolls that were previously difficult to machine with conventional tools, drastically improving
machining efficiency.
SUMIBORON Binderless : NCB100
SUMIBORON Binderless is a polycrystalline cubic boron nitrid (CBN) that directly binds nanometer- or sub-micron-level CBN particles without binder materials. Binderless CBN is harder and has better thermal conductivity. Therefore, it enables higher efficiency and longer tool life in machining of hard-to-cut materials, such as titanium alloy and cobalt-chromium alloy.
