General Features
In 1977, Sumitomo Electric Hardmetal successfully developed a revolutionary
CBN sintered tool - SUMIBORON.
The main component in SUMIBORON is Cubic Boron Nitride with a special
ceramic binder sintered under super high pressure and temperature. As
compared to other conventional tool materials, CBN has higher hardness and
excellent heat resistance. With these distinct characteristics, SUMIBORON can
perform machining of hardened steel, high hardness cast iron and exotic metals
where previously only grinding was done. Furthermore, excellent efficiency and
longer tool life can also be achieved from high speed machining of cast irons.
The sintered CBN tool - SUMIBORON is mainly used for the machining of ferrous metals due to its
low chemical reactivity with iron. There are 3 different classifications of CBN grades as follows:
A) in the chart below shows high CBN content group, where each grain is fused together. Applicable
for the machining of high hardness materials like cast iron, heat resistant alloys and carbides.
B) below shows a group where CBN grains are held together with a special ceramic binder which has a strong binding
force. These provide excellent wear resistance and toughness in the machining of hardened steel and cast iron.
C) below shows SUMIBORON with a special ceramic coating (Coated SUMIBORON). The CBN
substrate along with the coating layer exhibit hardness, toughness, heat resistance and oxidation
resistance, required by a tool material for excellent cutting performance.

General Features
Coated SUMIBORON Series, achieving higher
speed, efficiency and 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.
Cutting edge specications in the Coated SUMIBORON Series have been
expanded to deliver performance in high precision machining and burr control.

Advantages of Hardened Steel Cutting with SUMIBORON
Below is an analysis on the use of CBN as compared to grinding:
In terms of cost investments, 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 surface finish, inserts
can machine different profiles with excellent surface finish, in a single set-up. Environmentally,
sludge treatment for grinding is a hazard to the environment but the chips from the turning process
can be collected and recycled.

Advantages of Sintered Component machining with SUMIBORON
As compared to carbide or cermet, edge wear is very small for SUMIBORON, which also has better wear resistance and can be form to a sharp edge easily.
Good machining precision and surface finish can be achieved because SUMIBORON is able to prevent burrs and chipping on the edges of the workpiece.

For general sintered alloy, carbide and cermet can perform up to
vc=100m/min. But around vc=120m/min, wear growth becomes rapid and
surface roughness deteriorates with increased burrs. On the other hand,
SUMIBORON exhibits stability and superior wear resistance, burr
prevention and surface roughness especially at high speeds.

High-Purity Ceramic Binder
With the newly developed high-purity
ceramic binder, the BN1000/BN2000 achieve
toughness and improved heat resistance
by decreasing impurities to an extreme!
BN1000/BN2000Conventional Grade
The impurities contained in the ceramic binder for conventional
grades brings about a strengthening in the sintered body and
a decrease in heat resistance, which becomes the cause of cracks
(chipping) and wear.

Characteristics
Excellent for finishing of Sintered Alloy
Excellent machined surface finish and surface appearance.
Available with 5 different types of edge treatment for machining sintered alloys of any shape or hardness
The LF type has a sharper edge designed specifically for machining sintered alloys with minimal burr and improved machining
precision. The HS Type has a strengthened cutting edge for stable chipping resistance during interrupted cutting and finishing.
Provides machining stability by reducing the variation in early milling surface roughness with the LE edge treatment, which emphasizes superior surface finish.
The LS Type, excelling in fracture resistance and cutting edge balance, also supports finishing that includes light interrupted cutting.

SUMIBORON
From Finishing to Roughing of Cast lron and Exotic Alloys!
General Features
New solid structure CBN insert. As all the edges can be used, total
machining cost will be lower, compared to conventional CBN inserts.
Biggest demand for this insert will be in Cast Iron machining. As
conventional brazed CBN inserts are not suitable for high speed cutting
and roughing, BNS800 can be used even for high speed finishing
processes with many times the tool life of ceramic inserts. Additionally,
RM type cutter is developed exclusively for Solid SUMIBORON and is
suitable for high-speed rough milling.
Characteristics
Larger Cutting Depths
100% solid CBN structure where the whole edge can be use.
High Precision Machining
Excellent balance of wear resistance and toughness.

The wiper flat offers good surface finish and improved efficiency.
WG Type: Recommended feed rate of f = 0.20 or lower (Surface Finish Rz = 1.6 to 3.2 μm)
WH Type: Recommended feed rate of f = 0.20 or higher (Surface Finish Rz = 1.6 to 3.2 μm)
Lineup includes five grades (BN2000, BNC2010, BNC2020, BNC200, BNC160) to suit different
cutting speeds.

SUMIBORON Insert and Edge Preparation
All SUMIBORON inserts are enhanced with the optimum cutting edge
preparation for the various grades and geometries (shown on the right).
This is to avoid cutting edge fracture caused by the heavy loads generated
during the machining of high hardness materials such as Hardened Steel.
As the pioneer of CBN tools "SUMIBORON," various selection of grades
and edge preparation combinations is our strong point for Hardened Steel
machining.

Recommended Cutting Conditions
Spindle speed nMore than
2,000min-1
Low speed may cause
chattering and chipping on the
cutting edge.
Depth of cut ap0.01 to 0.2mm
Excessive depth of cut may cause
larger tool deformation resulting in
deterioration of bore accuracy.
Feed rate f0.01 to 0.1mm/rev
Important notes
(1) Shorten overhang as much as possible (Max. L/D=5).
(2) Even minor workpiece run-out may affect tool life.
(3) Select a boring bar with a diameter closest to the bore
diameter.
(4) Although it is difficult to increase the rotational speed in
small diameter boring applications, higher speeds are
recommended whenever possible.
BNBX
Boring & Facing
Newly developed high rigidity slit-clamping system,
excellent for small hole boring
• Maximum overhang of L/D=5 possible.
• Minimal bar deformation produces excellent boring accuracy.
• Minimal vibration produces superior surface finish.
• Easy bar indexing without sleeve removal.
BN2000 for hardened steel and BN7000 for sintered
alloy are available
* BNBX bars can be use with HBB type sleeves, however, HBX type sleeves are recommended for bars below ø6mm.

Recommended Cutting Conditions
1. Use a machine with high rigidity for stable cutting.
2. Non-water soluble coolant recommended. Supply as a mist or external coolant. Take fire prevention precautions to avoid fire
hazards caused by sparks igniting during machining or tool breakage.
3. Shorten overhang as much as possible.
4. Adjust cutting conditions as necessary as machine rigidity and other conditions may vary.
5.
Depth of cut shown in the table of conditions are maximum depths. Adjust the actual depth of cut to the desired machined surface finish.

(1) Use a rigid machine and select a high cutting speed with low
feedrate.
(2) Use dry cutting conditions.
(3) Make overhang as short as possible.
(4) If work hardness is lower than HRC50, try a coated or
uncoated carbide ballnose endmill instead. (¦I58)
