MX3030
Cermet Grade for Milling

Expands The Effective Application Range of Cermet Grades
Enables excellent surface finishes even at highly efficient machining conditions.
Improved machining efficiency by maintaining excellent surface finishes even at large depths of cut.
Cermet has a low affinity with iron, excellent thermal stability and oxidation resistance, and is a suitable grade for finishing.
However, it does not have the same bonding strength as cemented carbide, and the challenge is to compensate for fracture resistance.
MX3030 has higher thermal conductivity than conventional products and has excellent thermal cracking resistance. Therefore It is possible to suppress wear and maintain the surface finish.
Also, since it has excellent toughness, it can be expected to improve machining efficiency through machining at large depths of cut.
