Other Data:


E-F is a manual single disc grinding and polishing machine designed for metallographic specimen preparation, capable of handling low-volume and flexible sample preparation needs in both laboratories and production lines. With the E-F machine, users can grind and polish sample surfaces to a mirror-like smoothness, enabling various applications such as metallographic microstructure observation, metallographic analysis, material analysis, and hardness testing of metal materials or other materials.

On the other hand, E-FR is a manual dual-disc grinding and polishing machine specifically designed for metallographic sample preparation. Its dualdisc operation feature allows simultaneous processing of two samples, further enhancing preparation efficiency.

 Metallographic grinding and polishing machine E-F and E-FR can accommodate samples of various sizes without being limited by dimensions. Both E-F and E-FR offer flexibility and convenience when dealing with different types and sizes of samples, satisfying diverse demands in metallographic processing work. They help users easily prepare samples and obtain accurate and clear test results.

Fiber-Reinforced Plastic (FRP) body cover

FRP body cover design is easier for maintenance and endurable.


Platen speed and direction adjustable

Adjust the platen speed and rotational direction based on the sample materials.


Intuitive display design

Intuitive display design is easy to learn for operators.


High effective brushless motor

Low rotational speed and high torque ensure the precision of grinding/ polishing, and also has longer lifespan.


Multiple choices of platens are suitable for various consumables

Platen can be rapidly replaced. According to the feature of the consumables, such as PSA back SiC papers, plain back SiC papers, diamond discs, and polishing cloths, to apply with suitable platens.


Expand platen is for a wider size sample grinding/ polishing

Different from the restriction of 8” and 10” platens, platen size of Ø300mm (12”) increases the sample size for grinding or polishing.


Irregular shape sample grinding/ polishing

Manual operation without the restriction of sample’s shape.


Compatible with dispenser (Option)

Opting for a dispenser can distribute diamond suspension or aluminum suspension automatically.



Flexible operation with dual platens (E-FR)

Dual platens increase the efficiency of the application for platens. Grinding and polishing can be able to process at the same time.
