For the metallographic equipment normally configured in the metal laboratory, the small series has introduced the metallographic sample cutting equipment and inlaying equipment before. Today, we introduce the metallographic polishing machine commonly used in the metal laboratory.


The key steps of metallographic inspection are grinding and polishing. The common grinding and polishing equipment are belt polisher and high-speed disc polisher. At present, disc metallographic polisher is more widely used. It can be grinded and polished manually or automatically. The technology is very mature. The specific application depends on the equipment conditions, technical requirements and the working habits of metallographic engineers.

Manual metallographic polishing machine


The price is economical and the operation and maintenance are simple. It is a manual metallographic polishing machine. It has two models: single disk and double disk. It is suitable for grinding and polishing of various materials. It is a very economical and practical equipment.


In the case of a small number of laboratory samples and few operators, a single disk manual metallographic polishing machine is enough. The relative sample preparation quantity is large, and there are more than two operators, or for teaching use, generally, double disk can be selected, and one can be used for two, saving space and purchasing cost.

Automatic metallographic polishing machine


Automatic metallographic grinding and polishing machine is also a metallographic grinding and polishing equipment currently used by many metal laboratories. Because it has both manual mode and more flexible application. Moreover, it can program and store multiple preparation programs, and can grind and polish multiple samples at the same time. It has high efficiency, and the effect of repeated sample preparation is remarkable. It is suitable for batch sample preparation, especially for sample preparation with large amount of sample preparation and good repeatability.


If it can be compatible with the automatic liquid feeding system and realize the whole process automatic control, it can fully realize the full-automatic grinding and polishing. Although the price is relatively high for manual operation, it is also cost-effective in terms of saving labor costs and improving work efficiency. Therefore, for laboratories with sufficient procurement budget, automatic metallographic polishing machine is a good choice.

The manual and automatic metallographic polishing machines described above are suitable for metallographic grinding and polishing of various materials. Metal laboratories can reasonably select and match them according to specific needs for research, teaching, quality detection and control. If you need more information, you are welcome to consult with pulse detection engineers and provide you with professional proposal wholeheartedly.
