Guidance for SUMIBORON Grades
Sintered
- Advantages of Sintered Component machining with SUMIBORON
SINTERED COMPONENT
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.
MACHINING
Good machining precision and surface finish can be achieved because SUMIBORON is able to prevent burrs and chipping on the edges of the workpiece.
