Achieve Highest Flatness and Reproducible Results in Al and Ti Sample Preparation for Quality Control in the Aerospace Industry

For industries like Aerospace this is particularly important. Turbine blades, for example, are exposed to exceptionally harsh conditions resulting from a combination of high operating temperatures and radial tensile stresses. With reliable machines and consumables for materialographic sample preparation, high standards can be met to ensure correct analysis of all parts.

Make yourself familiar with QATM machines and consumables and learn how grinding discs can contribute to improved sample preparation.

A broad portfolio of grinding discs with different bonding systems, grain types and grain sizes enable the preparation of all kinds of materials for all kinds of industries. In industries like Aerospace quality standards are particularly high. Materialographic sample preparation is an important step in quality control or product development. Highest quality and reproducibility in the results are required of the equipment and consumables.

The new POLARIS grinding discs represent one of the latest innovations in sample preparation. POLARIS M is available with diamond grains of down to 3 µm to reduce preparation time and save polishing steps. POLARIS SIC utilizes common silicon carbide abrasive grains. Soft to medium-soft materials like aluminum, titanium, soft steels or composites like CFC can be easily prepared using POLARIS SIC or POLARIS M discs with convincing results. 

As an alternative to the widely used SiC ginding paper, grinding discs provide several advantages over this conventional grinding medium:

• High flatness and edge retention due to stiff steel carrier
• High reproducibility due to constant abrasion rate
• Well-suited for automatic grinding machines
• Directly applicable on magnetic working wheels (no clamping ring or other tools required)

One of the biggest advantages of grinding discs is the generation of very flat samples with preserved edge retention as a result of the hard steel carrier. Unlike abrasive paper where grains wear out quickly and thus change the grinding behavior and surface finish of the samples, the grinding discs provide a constant abrasion rate over the whole grinding process. With a tool life comparable to up to 100 SiC-papers for POLARIS SIC and up to 1000 for POLARIS M/H, grinding discs represent a more ecologically friendly preparation method.

Reliable and reproducible results can be generated by using them with our automatic machines, for which they are particularly well-suited. (Learn more about QATM grinding machines. The discs do not require initial dressing. The steel carrier is coated with a rough layer on the back which ensures a safe grip when directly applied to magnetic working wheels.
