Everything about polishing
Superficial by no means: polishing is more than just a pretty appearance
When specimens have been ground down to the finest grain size in the laboratory, the surface is then polished as smoothly as possible. This is usually not for aesthetic reasons, but ensures that even minimal irregularities can be reliably abraded and removed. After all, only when the surface has been polished to a mirror-smooth finish can further processing and analysis of the specimens succeed.
Polishing machines and polishing agents for optimum results:
For perfect results, you naturally need the perfect laboratory equipment. And that is exactly what you will find in our online store. The grinding and polishing equipment from the LECO range all impress with their ease of use and high-quality workmanship. Just one example are the polishing systems of the PX400/PX500 series. These are equipped with 30 pre-installed preparation methods, each of which can be individually adapted to your requirements. Handling is done via a touchscreen with graphical user interface and is very convenient. Just like the other polishing machines from our store, you can also order this model in different versions. In addition to the equipment and automatic machines, threeconsumables are usually required for optimal polishing, which can be used to produce the required surface quality for microscopic analysis and hardness testing:
- - Polishing cloths:
Our polishing cloths form the basis for the polishing process and are available in different variants. Hard woven cloths, for example, are suitable for pre-polishing while softer cloths are ideal for final polishing.
- - Polishing agents:
Polishing agents from LECO ensure the desired stock removal during metallographic polishing and can be ordered from us as diamond paste, diamond spray or liquid diamond suspension. Thus, you will find exactly the right polishing agent for every polishing application.
- - Lubricant:
Our polishing lubricants ensure an even distribution of the abrasive on the polishing cloth and thus create the necessary lubricating film for a professional polishing of your samples.
In addition to the diversity of our range, the quality of the products is one of the main reasons why so many laboratories, companies and organizations place their trust in LECO. Convince yourself and let us advise you personally.
