The QG-100Z is a high-performance floor-standing metallographic cut-off machine with a screen-displayed PLC system, simple operation and strong capability. Spindle speed is 2840 r/min, maximum cutting diameter reaches 100 mm, the cutting table measures 300 × 280 mm, and the cutting speed is steplessly adjustable from 1–50 mm/min with a limit of 99 mm/min. The automatic circulating coolant system protects the specimen from burning during cutting.

Working principle
How precision sectioning works
A rotating cut-off wheel advances into the specimen under flood coolant, keeping heat and deformation low enough to preserve the true section.
- Wheel matched to material
- 4-channel coolant
- Low feed rate protects edges
Product overview
Product overview
A metallographic cut-off machine is used to take test specimens. Improper sectioning makes later examination meaningless, so choosing a suitable cutter matters. Select the machine mainly by the size of the workpiece: small parts suit cutters with a small cutting capacity, while larger workpieces require a larger capacity. Match the cut-off wheel to the material for a clean, burn-free cut.
Applications
Metallographic cut-off machines are widely used in the following areas:
1. Metal processing and quality control: precise sectioning of steels and non-ferrous metals to prepare specimens for microstructure analysis, quality control and defect inspection.
2. Aerospace: sectioning high-precision parts such as aircraft and rocket engine components to verify that their microstructure meets requirements.
3. Automotive manufacturing: sectioning body and engine components, supporting material selection and durability engineering.
4. Research and teaching: an essential laboratory instrument in institutes and universities for materials research, structure analysis and teaching experiments.
5. Petrochemical and power industries: sectioning pipes, tanks and similar equipment during maintenance and material inspection.
6. Tooling and die making: precise sectioning that supports efficient, high-quality die manufacturing.
7. Electronics and precision manufacturing: component testing and sectioning of ceramics and semiconductor materials.
8. Other fields: construction, bridges and shipbuilding; mineralogy for constituent and particle analysis; and biomedical sampling.
