Brand：P20G-1-A3 Series
Other Data：
The automatic spring pressure grinding and polishing machine (P20G-1-A3) is a specialized single disc polishing machine used for metallographic specimen preparation. It is equipped with a spring pressure grinding head, allowing the adjustment of the pressure force during grinding and polishing according to the requirements of metallographic specimen preparation and the material of the sample, to achieve high-quality sample surfaces. Such features make it convenient for metallographic microstructure observation, metallographic analysis, material analysis, and hardness testing of metal materials or other materials.
The design of the spring pressure grinding head ensures even distribution of pressure force, effectively avoiding potential issues of uneven polishing. This is crucial in the metallographic pre-processing process to ensure the accuracy and reliability of subsequent metallographic analysis.
Features
Superior industrial material body
Exquisite Appearance
Streamline appearance design and glossy film surface finishing makes the mechanical appearance artistic and exquisite.
Intuitive design and metal button operating panel
Equipped with durable high-quality metal buttons makes the design intuitive.
Rotational speed of the head is adjustable
The grinding head is equipped with brushless motor with rotation speed from 10~170rpm
Dispenser (Optional)
External dispenser can precisely control polishing process and replicate the same procedure.
Automatic drying function
The graphic visualization drying function can make the cleaning process more fast in order to avoid the cross contamination during the operating process.

Grinding speed can be adjusted to a minimum of 10 rpm. With external dispenser, it can meet the need of long-time polishing without deformation.
Modular design
The combined control box can be fixed behind the machine or be placed next to the machine with quick-change design, which is easy to clean and can maximize the space.
Individual pressure (A/B type)
The press force is 1.4~5kg which can be controlled based on the material of the specimen.
Central pressure (C type)
The press force is 3~5kg which can be controlled based on the material of the specimen.
Various choices of platen
Platen size of 8” and 10”are suitable for any consumables application.
Retractable water hose
Clean the machine conveniently.
Various anti-splash application
Various anti-splash covers can be applied based on the method of polishing process.
