Grinding & Polishing Designed, Developed, and Manufactured by TOPTECH. The automatic air pressure grinding and polishing machine (P20G-1-R6) is a specialized single disc grinding and polishing machine used for metallographic specimen preparation. This machine is equipped with a pneumatic pressure grinding head, allowing precise adjustments of polishing and grinding parameters such as pressure force, disc speed, head speed, and preparation time according to the requirements of metallographic preparation and the material of the sample. By adjusting these parameters, it can produce samples with high surface flatness and precision.


Mounting Press Designed, Developed, and Manufactured by TOPTECH. MV01A is a specialized high-capacity intelligent vacuum impregnation machine for metallographic specimen preparation, capable of handling multiple samples simultaneously, thereby improving the production efficiency of sample cold mounting. The intelligent design makes the operation more convenient and flexible. Users can precisely adjust the vacuum level and pressure holding time based on specific sample characteristics to ensure parameter control and processing effects during the preparation process, thus enhancing the stability and consistency of sample cold mounting.


Diamond Saw Designed, Developed, and Manufactured by TOPTECH. Designed specifically for petrography, the CLG50 cuts and grinds hard, brittle materials. Its integrated system enables grinding immediately after cutting, preventing thickness deviation and breakage caused by secondary clamping.
With 1 μm cross-feed resolution, it reliably produces ultra-thin rock sections down to 40 μm with ±10 μm cutting and grinding accuracy, enabling clear microscopic observation of mineral crystal structures.


Precision Cutting Designed, Developed, and Manufactured by TOPTECH. The CK260B Precision Cutting Machine Series offers a maximum cutting capacity of Ø120mm, high rigidity, low vibration, and an automation-ready heavy-duty cutting structure with industrial-grade intelligent overload protection, delivering stable and reliable cutting performance.


Grinding & Polishing & Cleaning Designed, Developed, and Manufactured by TOPTECH. Auto Grinder & Polisher & Cleaner (Air pressure) is your all-in-one solution for grinding, polishing, and cleaning!
Compared to manual operations, it saves over 80% of engineers' operation time, making your experiment more efficient and effortless!
After completing the grinding and polishing process, the machine automatically performs ultrasonic cleaning to thoroughly remove residual particles from the sample surface, effectively preventing cross-contamination.

TOP TECH diamond cutting blades are available in 75–300 mm diameters, 0.5–2.0 mm thicknesses, and four bore sizes for glass, ceramics, quartz, graphite, carbide, non-ferrous metals, and other hard or brittle materials. Available in electroplated, metal-bonded, and resin-bonded types, they offer strong cutting performance, long service life, or reduced sample damage.
CBN blades are available in 125–175 mm diameters and 0.5–1.2 mm thicknesses for steel, cast iron, and other ferrous materials. Combined with TOP TECH cutting machines and recommended parameters, they produce precise, low-damage surfaces while preserving the sample’s true microstructure.
