QATM Grinding consumables

Mechanical grinding is a machining process using bonded abrasive grains to level and smooth the specimen surface.
Silicon carbide (SiC), aluminum dioxide (Al2O3), silicon dioxide (SiO2), zirconium dioxide (ZrO2), diamond or cubic boron nitride (CBN) are used as abrasives.
Qprep grinding media achieve low-deformation material removal while keeping the number of preparation steps as low as possible

Grid to grain size conversion chart

The values provided are only intended as guidelines. Grit sizes are considered as a range, rather than a specific value. The Federation of European Producers of Abrasives, known as FEPA, and the American National Standards Institute, known as ANSI, as well as the Japanese Industrial Standards Committee (JISC) are the respective organizations that define these standards and are the basis for the conversion. QPREP abrasive paper conforms to the European FEPA P standard.

The process of grinding is divided into three categories in materialography:

Planar grinding stones for perfect metallographic sample preparation

If highest stock removal with highest planarity in the shortest time is required, the use of a planar grinding stone in materialographic specimen preparation is essential. In combination with our powerful automatic Qgrid XL planar grinding machine or our grinding and polishing automat Qpol 300 BOT, even high sample throughputs can be efficiently planar ground.

Product Advantages

Short machining time
Excellent planarity for all materials
Optimized removal rates with Qgrind XL stock removal monitoring
Ideal preparatory work for polishing on our Qpol polishing machine series

Recommended applications

Primary material control with high sample throughput
Serial inspections

Diamond grinding discs for perfect metallographic sample preparation

Product Advantages

High lifetime
High planarity
Sample preparation with high edge retention
Sustainable and eco-friendly

Range of grinding and polishing systems	Removal rate (with newly dressed / cleaned disc and same grit sizes)	Surface quality (with newly dressed / cleaned disc and same grit sizes)

QPREP provides a comprehensive portfolio of grinding discs with different bond systems, grain types and gain sizes. This way always allows to find the best solutions for individual requirements. All abrasive elements are on a metal carrier. So they can be directly applied on the QPREP magnetic foil without further tools. The grinding elements have just minimal resilience and ensure a planar surface with high edge retention. By this, it will gain stock removal free of smearing and chipping. QPREP grinding discs realize short preparation times and have in parallel long life times. Thus, will importantly contributes to a sustainable and resource-saving process in materialography.

Diamond cup grinder for perfect metallographic sample preparation

If a specimen with parallel faces is desired after precision cutting the use of a diamond cup wheel for further processing is recommended. Used in our precision cutting machines Qcut 150 M, Qcut 150 A and Qcut 200 A with vacuum specimen holder, the QPREP diamond cup grinder enable the user to achieve optimum planar parallelism with high surface quality and reproducibility.

Product Advantages

Planar parallel sample preparation
Stock removal with high accuracy
Very high repeat accuracy

Recommended applications

Target preparations
Defect analysis
Thin section technology
Petrographic examinations

Grinding belts & tools for perfect metallographic sample preparation

QPREP grinding belts can be used very well for manual pre-grinding and deburring. They are waterproof and very robust for wet grinding with the Qgrind 100.
