Precision cut-off machines for metallography
Precision cut-off machines produce clean, controlled cuts with minimal thermal and mechanical damage. They often work wet-cooled with diamond or CBN wheels to preserve microstructure and reduce polishing time. Twist Drill is available for drilling tasks.
Cut Precisely, Analyse Reliably with Precision Cut-off Machines
Precision Cut-off Machines deliver controlled separation of components so that microstructure and failure features remain intact for subsequent examination. These precision cutters work with wet cooling and thin-diameter diamond or CBN discs to reduce heat input and mechanical stress, resulting in minimal sample damage and reproducible cross-sections. Using an optimised feed control and precise clamping, the equipment ensures cuts at defined positions with low kerf loss — crucial for fragile, small or high-value samples.
Fewer Preparation Steps, Quicker Microscopy Results
A cleaner cut directly reduces the time spent on grinding and polishing. Because the initial cut produces a smoother surface, laboratories benefit from less polishing time and faster throughput per sample. This efficiency translates into more reliable results under optical or electron microscopes and a steadier workflow for metallography, quality control and research environments.
Protect Fragile Materials and Preserve Valuable Specimens
When working with soft metals, ceramics or layered composites, controlled cutting prevents plastic deformation, smearing and microcracks. The combination of low cutting force and targeted cooling leads to higher repeatability and reduced risk of sample alteration. For one-off or costly components this means more usable data from a single specimen and less waste of materials.
Exact Uses: From Electronics to Hard Materials
Precision cutting is essential wherever the true internal structure must be revealed without artefacts: electronics and PCBs, wires and stranded conductors, coatings and heat-affected zones, hardmetals and ceramics, and thin foils. Operators use these machines to produce analysable cross-sections for failure analysis, process control, R&D and certification tasks — in short, wherever a representative and analysable sample is required.

FAQ
What is a precision cut-off machine used for in metallography?
A precision cut-off machine is used at the very beginning of sample preparation to cleanly and controllably separate a workpiece into an analyzable specimen. It enables observation of the true microstructure—grain structure, phases, cracks, porosity, coatings and heat-treatment effects—without introducing cutting-induced alterations such as excessive heat, plastic deformation, microcracks or material loss. These machines typically cut wet-cooled with diamond or CBN wheels to minimise damage and reduce subsequent grinding and polishing time.
How does a precision cut-off machine protect delicate samples like thin foils or brittle ceramics?
Precision cut-off machines minimise cutting forces, use thin cutting wheels to reduce material loss, and apply controlled or force-regulated feed to prevent smearing, deformation or chipping. Wet cooling and appropriate abrasives (diamond/CBN) reduce the heat-affected zone and preserve the specimen’s true microstructure, making them ideal for thin sheets, wires, ceramics, hardmetals and electronics components.
How should I choose coolant and abrasive for optimal results with a precision cut-off machine?
Choose coolant that provides sufficient cooling and lubrication for the material—water-based coolants are common for many metals, while specialized coolants may be better for certain alloys or composite materials. Match the cutting wheel material to the workpiece: diamond for non-ferrous and hard brittle materials, CBN for hardened steels. Consider wheel thickness and feed rate to balance cutting speed, heat generation and material loss.
Can a precision cut-off machine reduce the time needed for subsequent grinding and polishing?
Yes. Because precision cut-off machines produce smoother, more even cut surfaces with minimal deformation and a small heat-affected zone, the amount of material that needs to be removed during grinding and polishing is reduced, speeding up the overall sample preparation process.
