The first step in metallographic sample preparation consists in sectioning a sample from a larger given piece to obtain a representative cross-section. Sectioning a material without causing structural changes defines the perfect cut. Abrasive cut-off wheels are made of abrasive particles bonded with a resin, a resin/rubber or a rubber matrix. They are designed to wear away, continuously exposing sharp new abrasive particles.

A "Soft" wheel is used for cutting hard and brittle materials. It provides new surfaces of cutting abrasives more rapidly while the bond breaks down. The "Hard " wheel has a slower break down bond rate, which is suitable for soft and ductile materials. Adequate cooling is required to remove debris and avoid thermal damages to the sample. The careful combination of particle type, particle size and wheel hardness helps prevent burns and distortions, yet provide maximum useful life. Cutting requires a sufficient amount of pressure to be applied to the abrasive wheel while cutting, excessive pressure will cause the abrasive wheel to stall or break. Cut-off wheels with aluminum oxide as the abrasive are generally used for cutting ferrous samples, alloys and most other metals. Silicon carbide is recommended for non-ferrous and other non-metallic materials.

The Sectioning catalog is available in PDF format.

SELECTION TABLE  •  WAFERING DIAMOND WHEELS


Wafering blades made of metal have diamond particles bound along the outside edge of the blade. The diamond blades are available in a resin or a metal bond.

For sectioning with a wafering blade, a slow speed and an adequate coolant should be selected. The pressure to the wheel/sample contact point should not be applied with excessive force. To remove any metal debris, it is recommended to dress the wafering blade using a dressing stick. Metal Bond blades are recommended for alumina, ceramics, nitrides, zirconia, electronic packaging and soft metal base alloys. Cubic Boron Nitride blades are designed for ferrous and nickel-based super-alloys.

   CUTTING SOLUTIONS


There are two recommended cutting solutions for sectioning. Rust/Coolant Inhibitor is used when sectioning samples using large loads at high speeds. The coolant should be directed at the contact point between the section being cut and the abrasive wheel. The flow should be uniform on both sides of the wheel.

Cutting oil is used when performing precision sectioning at low speeds.
