Release of MBS140, A Solid CBN Insert

June 15, 2005
  Mitsubishi Materials Corporation has recently developed and manufactured a new solid CBN insert, MBS140. This new insert will start to be sold by Mitsubishi Materials Tools Corporation (President: Osamu Takata, Headquarters: 1-6-1 Yokoami, Sumida-ku, Tokyo).
MBS140  Product Requirement and Background.
Conventionally, CBN has only been used for finishing tools to achieve high-speed, high- efficiency production, but to further improve production speed and efficiency, CBN tools now also require the ability to rough machine. However, conventional CBN tools are usually a brazed construction and the size of the CBN part brazed on the tool limits the achievable depth of cut. As a result CBN tools could not usually be used for roughing. To solve this situation the new solid CBN(1) inserts, MBS140, are made entirely of sintered CBN, and therefore do not limit the depth of cut. This allows for high speed and efficient roughing of cast irons with a 2mm-3mm depth of cut. Mitsubishi Materials Corporation believes MBS140 can help enhance cast iron machining and improve productivity.

Key features of MBS140 are as follows.

1.
The whole insert is composed of sintered CBN. This enables cast iron machining at larger depths of cut.
2.
The use of 2µm middle size CBN particles and a special binder allows it to deliver high performance even during the high load machining of cast irons.
3.
All four cutting edges of the insert are usable, thereby achieving efficient tool utilization and cost cutting.

 

< Word explanation >
(1)Solid CBN:
  • Conventional CBN tools have a sintered CBN piece brazed only at the cutting edge of cemented carbide inserts. Solid CBN inserts have no brazed portion because the insert is composed entirely of sintered CBN.
