QATM Cutting consumables

The process of cutting, specifically wet abrasive cutting, is essential for materialographic sectioning of samples. In this process, cut-off wheels of different material thicknesses, abrasive particles and bonds are used on a corresponding wet abrasive cutting machine. These bond types can be synthetic resin, rubber, or metal. For the abrasives, aluminum oxide, silicon carbide, diamond or CBN is used. These abrasive particles are enclosed in a bond matrix.

Consumables for cutting applications

Benefits

Low thermal influence on the specimen during the cutting process
Wet abrasive cutting achieves very fine surface finishes after cutting
Optimum cutting shortens the further preparation process

Recommended applications

Separation of relevant inspection areas

As a rule, the following principle applies:

For hard materials, a cut-off wheel with soft bond is recommended.
This ensures fast breaking out of worn abrasive particles.
For medium-hard materials, a cut-off wheel with a medium-hard bond is recommended.
This ensures worn abrasive particles break out evenly.
For soft materials, a cut-off wheel with hard bond is recommended.
This ensures slow breaking out of worn abrasive particles.

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

PREMIUM CUT-OFF WHEELS for perfect metallographic sample preparation

Significant properties for cut-off wheels are wear (i.e., abrasion resistance), long lifetime and cutting performance. Characteristics of the wheel composition are the abrasive used (aluminum oxide, silicon carbide, diamond, cubic boron nitride (CBN) and the bond type (metal, resin or rubber). The goal of any cut is to separate the material with minimal deformation and temperature effect. For a clean cut, the abrasive particles and bond type of the cut-off wheel should be matched to the material being cut.

QPREP Premium cut-off wheels offer the optimal solution for a wide range of applications.

Achieve a fine cutting surface
Wide range of cut-off wheels for cutting all materials
The best cutting function fitting to the material
Low deformation and temperature during the cutting process
Very good cutting performance with long lifetime

The color coding of the premium cut-off wheels enables quick, visual assignment and identification of the several types.

COOLANTS AND ANTI-CORROSION AGENTS for perfect metallographic sample preparation

Optimum cooling is essential during cutting. Excessive heat generation during the cutting process damages the specimen as well as the cutting wheel. QPREP coolant and anti-corrosion agent help to dissipate the heat and remove chips at the cutting point. A corrosion inhibitor must be added to the coolant, otherwise there is a risk of oxidation on the cut-off surface of the specimen as well as on machine components.

Product Advantages

QPREP coolant and anti-corrosion agent are suitable for all types of cut-off machines
QPREP ATM CoolCut is known for its environmentally and user-friendly handling
QPREP coolant and anti-corrosion agent minimize the risk of thermal damage and corrosion during the cutting process

Recommended applications

Cutting additive for all and especially corrosive sensitive materials
When cutting coated samples that have been coated in a salt bath, the QPREP Defoamer should be used
For cutting polymers and composites, the use of the QPREP coolant and anti-corrosion agent for plastics and composites is recommended
QPREP ATM-CoolAdd CU is an additive to the cooling lubricant for specific requirements when cutting specific materials

FILTER SYSTEMS for perfect metallographic sample preparation

During cutting, various residual materials are produced from the specimen (chips) and from the cut-off wheel (wear/tear). To prevent these residual materials from entering the cooling water / waste water system or the pump mechanism, the use of filter systems is required. A suitable filter system with the correct mesh size, filter material and dimension has a significant influence on the cleanliness of the coolant.

Product Advantages

Various QPREP filter systems for different cut-off machines, from precision machines to floor standing machines.
QPREP filter systems protect the cutting machine and thus increase its lifetime.
The different mesh sizes of the filters offer an applicationoriented selection of the appropriate filter system for the corresponding recirculating cooling unit.

Recommended applications

The use of a filter system keeps the coolant significantly longer clean and prevents damage to the pump and machine.
