Benefits

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.

This grinding and polishing machine is not only suitable for metallographic specimen preparation but also finds applications in various fields such as inspection analysis, quality analysis, metallographic analysis, and material analysis. It provides an ideal sample surface for metallographic microstructure observation, making observations under a metallographic microscope clearer and more accurate. Additionally, this machine plays an important role in hardness testing for metal materials and other materials.

※Mobiles and tablets can be slid left and right.

Features

Superior industrial material body

 

Exquisite Appearance

Streamline appearance design and glossy film surface finishing makes the mechanical appearance artistic and exquisite.

 

 

Multi-functional control panel

It is equipped with a high-quality color touch panel, intuitive human-machine interface, and 10 modules of parameter memory function.

 

 

Low speed grinding and polishing function

Rotational speed can be lowered to 1 rpm. With external dispenser (optional), it meets the requirement of long-time polishing process without deformation.

 

 

Rotational speed of the head is adjustable

The grinding head is equipped with brushless motor with rotation speed from 10~170rpm.

 

 

Dispenser (Optional)

Users can control the dispenser by setting up the parameters on control panel.

 

 

Automatic drying function

The automatic drying function makes the cleaning process more fast. Also, avoiding the cross contamination during the operating process.

 

Overload protection

When the total force is more than the default setting during operation, the machine will stop automatically.

 

 

Sample Pistons

Sample pistons will lower down lightly to prevent the surface of the specimen from damage.

 

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 maintenance and can maximize the space.

 

 

 

Individual pressure

Pressing force is between 0.5~6kg. The suggested pressure and amount of samples are marked on the grinding head.

 

Individual micro force (Optional)

Pressing force is between 0.2~1kg. Suitable for the specimen, requiring the micro force pressing during grinding/polishing.

 

Central force (Optional)

Pressing force is between 3~12 kg. Quick-released sample holder simplifies the leveling process and cleaning process.

 

 

Various choices of platen

Platens with size 8” and 10“ are suitable for any kinds of consumables .

 

 

Telescopic water hose and air pressure gun

The machine can be cleaned conveniently.

 

Various Anti-splash application

Various anti-splash covers can be applied based on the method of polishing process.
