Cut Off Wheels
Specimens for metallographic analysis must never undergo structural changes during cutting. Kemet offer 3 different types of metallographic quality cut-off wheels for use on all cut off-machines:-
- aluminium oxide cut off wheels
- silicon carbide cut-off wheels
- diamond cut-off wheels.
The type of cut off wheel to be used depends on the type of material to be cut and in particular to its hardness. Please refer to the table below:
