Coated CBN Grade for Hardened Steel
MBC020 y Features
Application Range
MBC020 is a general purpose coated CBN grade suitable for continuous turning to light interrupted machining of hardened steel. The combination of high cutting edge rigidity and a coating for higher wear resistance allows MBC020 to cover a wider range of machining applications than conventional CBN grades.
MBC020 further expands the application range of high efficiency machining.

Coating for Higher Wear Resistance A special new coating, originating from MIRACLE technology, is used for MBC020. This coating technology gives superb wear resistance for machining hardened steels.

MBC020 utilises a “Particle-activated Sintering Method” during the manufacturing process. As a result, the cutting edge toughness has been increased and also provides superior wear resistance.

Why is a high hardness CBN grade coated using MIRACLE coating technology? MBC020 is a new coated type CBN to compliment the exisiting MBC010 grade. By applying a coating to the substrate, MBC020 can obtain a higher wear resistance. Why does a coating on a high hardness CBN grade increase wear resistance? CBN has a hardness value second only to diamond. Taking advantage of this feature, CBN tools are able to withstand high temperatures when machining hardened steels. However, for MBC020, MIRACLE coating technology has been used and covers the CBN with a highly heat-resistant ceramic coating layer that maximises the hardness properties. As a result, MBC020 displays a higher wear resistance than uncoated CBN inserts of the same grade.

y A Wide Variety of Edge Preparation Forms (Honing types) Cutting performance of CBN tools greatly depends on the type of edge preparation (honing). To make tools available with the optimum edge honing, Mitsubishi’s CBN insert series offers an additional 6 types of edge honing based on the 3 conventional honing types, namely F (for continuous cutting), G (for general purpose) and T (for interrupted cutting). For MBC020, to maximize the benefits of its grade properties, three honing types, GA (for general purpose), GN (for general purpose & for less crater wear) and TA (for interrupted cutting) are offered as standard.

y Features of Breaker Inserts Chip Breaker Geometry Designed for Excellent Chip Control R-shaped chip breaker ensures optimization of the cutting point and the chip breaker position. Enables effective chip discharge even when copying and prevents the chips from wrapping around the holder under the cutting conditions for finishing.
Long Life Coated CBN Grade The coated grade MBC020 made with MIRACLE coating technology exhibits high cutting performance over a wider range of machining applications from continuous to medium interrupted cutting and enables long tool life.

y Wiper Insert y What is a wiper insert? • The wiper insert is designed with a wiper edge that is situated where the straight edge meets the corner radius. Wiper • In comparison to conventional breakers, the surface finish does not deteriorate even if the feed rate is doubled. • Machining at high feed rates improves cutting efficiency.
a Improving Surface Finish
Under the same machining conditions as conventional breakers, but with the feed rate increased, the surface finish of the workpiece can be improved.
a Improving Efficiency
High feed rates not only shorten machining times but also make it possible to combine roughing and finishing operations.
a Increased Tool Life
When changing to high feed conditions, the time required to cut one component is decreased, thus more parts can be machined with each insert. In addition, the high feed rate prevents rubbing, therefore, delaying the progression of wear and increasing the tool life of the insert.
a Improving Chip Control
Under high feed conditions, the chips generated become thicker and are more easily broken, thus, chip control is improved.
Operational Guidance When using NP-CNGA / NP-CCGW types y No restriction for holders Standard holders can be used. ( A double clamp, high rigidity tool is recommended.)
*
End cutting angle
Non restriction
When using NP-DNGA type y Restriction for holders Use a holder with an end cutting angle of 93° for improving wiper efficiency. A holder with an end cutting angle of 91° can improve wiper efficiency (see the following figure), however, there is no wiper efficiency with other end cutting angles (60°, 90°, 107°etc.).

y Multi-corner Type Inserts • Single sided negative inserts are now included. • The same honing types are available for both single and double sided multi-corner inserts. y Double sided, multi-corner type insert Upper side
Underside
y Single sided, multi-corner type insert • A single sided, multi-corner type insert has no cutting edges on the underside. The type of grade is stamped on the upper side.
y Small Corner Radius Inserts • Corner R0.2 inserts now added to NP-TNGA and NP-VNGA types. Making it suitable for the machining of small work corner radii.
