Series expansion - “Full face CBN with hole” is added to “MB4020” CBN grade for sintered alloy and cast iron

October 15, 2013

Mitsubishi Materials Corporation has additionally launched a full face CBN with hole added to the series of “MB4020”, a coated CBN grade for machining sintered alloy and cast iron. This new series will start to be sold by Mitsubishi Materials Tools Corporation (President: Toshio Takizawa, Headquarters: 1-6-1 Yokoami, Sumida, Tokyo).

In recent years, with an increasing demand in requirements of automotive components, there has been a widespread shift towards the use of sintered alloy parts. Sintered materials offer high flexibility in material properties and freedom in manufacture complex forms. However sintered materials offer many advantages, they can also be difficult to machine. Tools used for machining of sintered alloy, need to able to meet certain criteria such as obtain excellent dimensional accuracy, surface finishes and also to prevent burr formation.
MB4020, CBN grade for the machining of sintered alloy and cast iron has been received a favorable reception as a tool that is suitable for use in a wide range of applications from continuous to interrupted machining. Because this ensures higher machining performance when machining various sintered alloys with different material properties such as hardness, toughness and properties.

We have decided to add a small diameter turning insert with full face and solid CBN with hole to “MB4020”, a coated CBN grade for machining sintered alloy and cast iron to handle for higher depths of cut and chamfering

Features of CBN grade for sintered alloy and cast iron “MB4020”

1.A general purpose grade for continuous to interrupted machining of sintered alloys. Suitable for the machining of various sintered alloys with different hardness and properties.

2.A newly developed special binder promotes the binding of the CBN particles. This means higher cutting edge rigidity can be achieved. When machining sintered alloy, it is necessary to reduce burrs and plastic flow. The MB4020 CBN tool grade offers high cutting edge rigidity allowing a sharper cutting edge and achieves ideal work piece tolerance.

3.High content CBN tool grade reduces welding of the work material on the cutting edge and stabilizes a component dimensional accuracy.

4.Full face and solid CBN can be used for a wide range of applications such as higher depths of cut and chamfering.
