In the field of research on metal materials, metallographic examination of microstructure is a commonly used scientific research method and means. By observing the microstructure of metal materials through metallographic samples, what preparations are required for metallographic sample preparation? After enduring for a long time, the editor finally couldn't help but write this list of metallographic equipment chopping hands, because the equipment of Chain Energy Metallographer is too comprehensive.


Chaineng Metallography is specifically responsible for the preparation of original imported material samples from Europe and America, the storage and supply of microscopic analysis instruments and equipment, hardness tester products, metallographic sample preparation consumables, equipment spare parts, and other full line products. At present, it is also a large inventory reserve and supply center for imported consumables in China, with a complete variety and sufficient inventory, which can fully meet the spot supply needs of large quantities of customers.


The process of metallographic sample preparation is mainly divided into four steps: cutting sampling, embedding samples, grinding and polishing samples, and inspecting samples.

    Step 1 cutting sampling: The original imported German QATM automatic precision cutting machine Brillant 210A is a compact wet precision metallographic cutting machine with manual cross feed. Up to five different operating modes, equipped with excellent cooling systems, user-friendly clamping arm systems, and no tools required for sample fixture and platform attachment replacement. 4.3” Touch screen control, intelligent ATM operation software, including consumables and program database, can create 200 user-defined programs. The diameter of the cutting blade is 3-8 inches. This precision cutting machine can be widely used for precision cutting and sampling of various materials, making it an ideal equipment for precision metallographic cutting.

Step 2: Embedding samples: The original imported German QATM fully automatic hydraulic metallographic hot embedding machine Opal 410, equipped with an automatic water cooling system, can simultaneously embed two samples. Microcomputer program control can automatically execute corresponding operations in sequence. The fully automatic bayonet sealing system can achieve fast and convenient opening/closing operation of the sample cylinder. The sample cylinder component can be quickly replaced without tools. The sturdy aluminum structure adopts powder coating, which is durable, beautiful, and easy to clean. Low noise, simple operation, and easy maintenance, it is a commonly used inlaid model in metallographic laboratories.

    Step 3: Grinding and polishing samples: The original imported German QATM single disc automatic metallographic grinding and polishing machine SAPHIR 250 A1-ECO, with a working disc diameter of 200-250 mm. The new work disk assembly system, new control software, and all preparation methods can be edited and stored, and protected through user account management. Pressure, speed, and rotation direction can be adjusted. The TOPAS ECO dosing system can be selected for use, providing more flexible operation and convenience for sample preparation. The shockproof plastic inner cover adopts powder coated aluminum outer cover and high standard technology of the equipment, giving it the characteristics of quiet and smooth operation and better preparation results. Simple operation, easy installation and maintenance, making it an ideal automatic grinding and polishing equipment for metallographic laboratories.

    Step 4 Sample Inspection: Whether it is a quick overview sample or a detailed inspection sample, the Leica DM6 M upright Leica microscope always meets the requirements with the appropriate settings. Leica DM6 M can achieve highly accurate and replicable fully automated analysis.

    From the first step of cutting samples to the later step of inspection samples, Chain Metallographer can meet all your needs. Chain Metallographer also has a professional after-sales service team, which can customize metallographic sample preparation plans for users for free. We can provide guidance on the application of metallographic sample preparation consumables until users can use them well and are satisfied! Users have no worries behind them. When is it better not to chop hands at this moment?
