HA-FRSD-A3 is an automatic dual disc and dual motor grinding and polishing machine designed specifically for metallographic specimen preparation. It features a dual disc independent control design, making it perfect for accommodating the preparation needs of flexible samples. The machine is equipped with a spring pressure grinding head, allowing users to flexibly adjust the grinding and polishing pressure according to metallographic preparation requirements and sample materials, resulting in excellent sample surface effects.
This machine is highly suitable for various needs, including metallographic microstructure observation, metallographic analysis, material analysis, and hardness testing of metal materials or other materials. The automation features of HA-FRSD-A3 make the preparation process more efficient and precise, helping users obtain accurate and reliable test results and significantly improving the efficiency of metallographic specimen preparation.
Features
Exchangeable grinding head for A type, B type, or C type
Exchangeable grinding head can be selected based on the demand of the sample preparation. This has increased the varsity selections for the sample preparation.
Individual pressure (A type and B type)
The individual pressure force is 1.4~5kg, which can be adjusted according to the sample of material.
Central pressure (C type)
The central pressure force is 3~5kg, which can be adjusted according to the sample of material.
A type Individual force
B type Individual force with calibration
C type Central force with calibration
Fiber-reinforced plastic (FRP) body cover
The FRP body cover design is easier for maintenance and endurable.
High effective brushless motor
Low rotational speed and high torque ensures the precision of grinding/ polishing, and also has longer lifespan.
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.
Multiple choices of platens are suitable for various consumables
8”, 10”, and 12” platens are available. 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.
Dual motors & dual platens design
Dual platens increase the efficiency of the application for platens. Platen rotational speed can be controlled separately for a flexible and convenient operation.
Compatible with dispenser (Option)
Opting for a dispenser can distribute diamond suspension or aluminum suspension automatically.
