Precision cut-off wheels for perfect metallographic sample preparation

Precision cutting enables cutting directly next to significant analysis areas and also for materials with particularly complex material properties. Precision cut-off wheels are significantly thinner than larger diameter cut-off wheels. With QPREP, you can choose from aluminum oxide, silicon carbide, diamond or CBN abrasives. The abrasives can be either electroplated, resin bonded, rubber bonded or bronze bonded. QPREP precision cut-off wheels are the ideal solution for cutting requirements with high surface quality and exact cutting accuracy.

Benefits

Minimal material loss due to thin cut-off wheel thickness
Allows cutting closer to the desired surface
Allows cutting of small, sensitive, and very brittle specimens

Recommended applications

Target and defect preparation
Electronic component segmentation
Preparing for thin sectioning specimens

Silicon carbide precision cut-off wheels

QPREP silicon carbide precision cut-off wheels offer the highest precision and surface finish when cutting complex components. Thanks to their tight manufacturing tolerances, they ensure a reliable and reproducible cutting process with a high degree of repeatability every time.

Product Advantages

Excellent surface finish
High repeatability
Exact cutting precision

Recommended applications

Optimal for cutting soft to medium-hard non-ferrous metals and alloys (e.g. copper, aluminum, and brass)
For preparation of demanding materials such as titanium and titanium alloys
Ensures precise cuts, ideal for accurate preparation of delicate components

Aluminium oxide precision cut-off wheel

For precision cutting of ferrous materials, QPREP Aluminum oxide precision cut-off wheels are the optimal choice. These cut-off wheels are available in two different grain types (fine and coarse). Coarse-grained cut-off wheels are ideal for fast and efficient cuts on low-hardness materials and produce a rougher surface. Fine-grained cut-off wheels are excellent for precise and smooth cuts on higher hardness materials, but with lower cutting speeds.

Product Advantages

The dense structure of the disc allows a longer lifetime
Less wear and less heat between specimen and cut-off wheel

Recommended applications

Suitable for a wide range of materials, especially various steel samples
Cutting of high alloy steel
Cutting of nitrided steel
Allows cutting through mounted samples

Diamond precision cut-off wheel

Um harte Materialien zu trennen, sind QPREP Diamant-Präzisionstrennscheiben die optimale Wahl, da diese Werkstoffe wie z.B. Keramik ohne zu verschmieren trennen. Die Bindung besteht aus Bronze. Die Diamanten im Randbereich können „abgerichtet“ werden, um die Schnittleistung der Diamantpartikel nach längerer Nutzungsdauer wieder voll nutzen zu können.

Product Advantages

Diamond as abrasive enables cutting of hardest materials
Separates hard material without smearing
The dressing function ensures that the diamonds always

maintain maximum cutting performance

Recommended applications

Dependence of diamond concentration on the toughness of the material
The optimal choice of diamond concentration improves efficiency and lifespan of the cutting discs
High concentrations (HC) ideal for universal use, hard metals, and hard/soft composite materials
Low concentrations (LC) are suitable for hard and brittle materials such as mineral samples, rock, glass, and ceramics

Order Data

CBN precision cut-off wheel

QPREP CBN precision cut-off wheels like the diamond precision cut-off wheels, are edged with a cubic boron nitride (CBN) abrasive in a bronze bond. The properties of CBN make it particularly suitable for composite and tough materials.

Unlike other abrasives, CBN is not made of carbon, making it an optimal choice for specific applications.

Product Advantages

The best cutting performance when cutting soft and hard materials
Separates hard material without smearing
The dressing functionality of our QATM cut-off machines ensures that the CBN particles edge area always maintain the highest cutting performance

Recommended applications

Composites and materials with a combination of soft and hard materials
Ductile materials
Cutting hard ferrous materials

Order Data

Saw blade cut-off wheel

The QPREP Saw blade cut-off wheel is particularly suitable for cutting materials with a high tendency to smearing.

Product Advantages

The best performance when cutting non-metallic material
Lower heat generation due to single engagement of the saw teeth during cutting
Since there is no binding of abrasives, the disc is odor and dust free

Recommended applications

Separation of non-metallic materials
Separation of plastic materials
Separation of polymers e.g., carbon fiber reinforced polymers
