HW-Piano(Granular)-Metallographic grinding disc Product Features
The polishing step can replace metallographic sandpaper, as the grinding pad’s working layer is optimized for the continuous supply of lubricant, improving the performance of the diamond grains. The surface structure ensures superior flatness across all samples.
Main abrasive material: High-performance diamond, designed in an granular shape. Various options are available for hard materials with hardness ranging from HV150 to HV2000.
Applicable materials:
Metals: High-speed steel, alloy steel, carbide, tungsten steel, tungsten carbide, etc.
Non-metals: Glass, ceramics, agate, stone, gemstones, jade, monocrystalline silicon, polycrystalline silicon, quartz glass, titanium carbide, magnetic materials, etc.
Application areas:
- Materials science, metal identification, failure analysis, manufacturing, materials research and development, diamond and gemstone craftsmanship, electronics and the semiconductor industry.
- Double-sided lapping machine, single-side lapping machine.

2. How to Choose
Specific applications should be determined according to the hardness of the workpiece material and your current processing needs.
Usage Instructions:
Place the grinding pad directly onto the magnetic machine plate. No need for polishing cloth or additional abrasives (polishing liquid); simply use tap water to start the grinding process.
For very sensitive sample processing, a non-corrosive liquid can be used instead of water as a lubricant.
To achieve precise sample flatness and ensure even wear of the grinding pad, the sample in the sample holder should protrude a few millimeters beyond the grinding pad’s working surface.
3. Precaution
- For optimal flatness, avoid sticking any labels or similar items to the bottom of the disc to prevent affecting workpiece flatness.
- Ensure that the contact surface between the grinding disc and the machine is very flat, clean, and dry to avoid impacting the workpiece’s flatness.
- After use, carefully remove the pad, rinse with water, and let it air dry.
- Avoid bending or damaging the precision grinding disc.
- When installing or removing, do so carefully to avoid magnetic attraction pinching your hands.
