The first step in preparing a specimen for metallographic or microstructural analysis is to locate the area of interest. Sectioning or cutting is the most common technique for obtaining this area. Proper sectioning has the following characteristics:

Selecting the right abrasive blade depends on the cut-off machine design and operator preference. Blades are characterized by abrasive type, bond type, and hardness, with the choice largely based on material hardness and whether it's ferrous or nonferrous. Resin/rubber blades emit more odor due to slight burning during cutting but have a longer lifespan. Resin blades, though more versatile and odor-free, wear down faster but offer a cleaner cut as the abrasive is continually renewed.
Historically, resin/rubber blades were more specialized, requiring extensive testing to match blade properties with machine parameters. These blades were popular in the US, but improved resins have shifted preference towards resin-bonded blades. Resin-bonded blades have long been favored in European and Asian markets.

Abrasive sectioning is ideal for cutting ductile materials like metals, composites, plastics, and rubbers. Selecting the right abrasive blade involves understanding the relationship between the abrasive type, bonding, and specimen properties.
Modern blades use alumina or silicon carbide abrasives. Alumina, tough and moderately hard, is best for ferrous metals. Silicon carbide, harder and self-sharpening, is ideal for nonferrous metals.
The bonding material should break down at the same rate as the abrasive dulls, optimizing efficiency. The right resin system depends on the sample's hardness and wear characteristics.
Variable speed saws enhance control by matching cutting speed to material hardness. Softer metals require slower speeds to minimize burrs, while harder materials benefit from higher speeds to expose sharp abrasives. For hardened steels, use 50% of the blade’s maximum speed to avoid overheating.
Lubrication and swarf removal during abrasive cutting and diamond wafer cutting are required in order to minimize damage to the specimen. For some older abrasive cutters, the proper cutting fluid can also have the added benefit of coating cast iron bases and the fixtures in order to reduce or eliminate corrosion.
TIP: Most abrasive cutters have a hood, which can produce a corrosive humidity chamber when not in use. In order to reduce these corrosive effects, keep the hood open when not in use.
Abrasive Cutting Fluid - The ideal cutting fluid for abrasive cutting is one that removes the cutting swarf and degraded abrasive blade material. It should have a relatively high flash point because of the sparks produced during abrasive sectioning.
