Double Disc metallographic Manual Grinder Polisher Sample grinding polishing machine Bench-top

The purpose of a metallographic sample grinding and polishing machine is to prepare material samples for microscopic examination by producing a flat, smooth, and mirror-like surface.

Main Functions:

1) Grinding – Remove surface irregularities:

Removes oxidation layers, scratches, and deformation using abrasive papers or grinding discs of different grit sizes to obtain a flat surface.

2) Polishing – Achieve mirror finish:

Uses polishing cloths and suspensions to eliminate fine scratches and produce a smooth, reflective surface suitable for microscopic observation.

3) Preparation for metallographic analysis:

A properly prepared sample allows clear observation of the material's microstructure (e.g., grain boundaries, phases, inclusions) under an optical or electron microscope.

4) Applicable to various materials:

Used for preparing samples of steels, non-ferrous metals, ceramics, composites, and more.

Typical Applications:

1) Quality control in manufacturing (e.g., evaluating heat treatment results, checking microstructure consistency)

2) Material research for studying structural characteristics

3) Failure analysis, to observe areas around fractures or defects

4) Educational labs in material science or metallurgy courses

Main features:

1. Supports continuous working mode and countdown working mode (Timing function). In continuous working mode, the machine will keep running if the stop button is not pressed; in countdown working mode, the machine will automatically stop working after the set time is completed.

2. 7’’ Color Touch screen with menu structure, operate very easy;

3. Double work discs, can do different grinding polishing work;

4. Multi-usage, metallographic specimen of coarse grinding, fine grinding, coarse and fine polishing, one machine to complete

5. Stepless speed 50-1000rpm + 8 constant speed design, setting more easier.

6. Easily manual replace magnetic anti-sticking disc, can make all kinds of sample of coarse and fine grinding, coarse and fine polishing all process (optional purchase)

7. One key to switch counterclockwise and clockwise rotation direction.

8. Low noise, stable working performance and beautiful outlook.

9. The faucet adopts stainless steel 304 material, which has good corrosion resistance

10. The shell is made of high-end ABS, which is novel and beautiful in appearance.
