Metallography the study of microstructure has been invaluable tool to the progress of science and industry for the past three centuries.  The key to obtaining an accurate microstructure is having a properly prepared specimen that is truly representative of the material being examined. To insure achievement of such true surfaces it is important that each stage of sample preparation be carried out not only with accuracy, but also with understanding what each specific stage must accomplish. This month we will concentrate on Sectioning, removal of a representative sample from the parent piece.

Abrasive Cut-Off wheels – Selection Factors.

Many factors affect the performance & cutting characteristics of abrasive cut off wheels.

1.       Abrasive Grain

        a.       Type AL₂0₃, SiC

        b.      Grit Size

2.       Bond
a.    Rubber
b.    Resinoid

        c.       Resin/Rubber

3.       Hardness (Grade)

        a.       Soft

        b.      Hard

4.       Density (Structure)

All Metlab Corp’s abrasive wheels have been specifically manufactured with all these considerations. Let us help you on the proper selection of your cut-off wheel needs.
