HW-SiC-I(honeycomb shape)-Metallographic Silicon Carbide Grinding Disc Product features
This lapping process can replace metallographic sandpaper. Due to the continuous supply of lubricants, the working layer of the grinding disc optimizes the working method of silicon carbide particles. The surface structure ensures better flatness for all samples.
- The main abrasive material is modified silicon carbide with a honeycomb design. It is specifically designed to replace silicon carbide sandpaper, with one grinding disc capable of replacing 200-300 sheets of silicon carbide sandpaper of the same specification.
- The product is available in stainless steel plate (magnetic).
- Product Features: Simple and Low Cost: One grinding disc can replace 200-300 sheets of silicon carbide sandpaper of the same specification.
- Consistent Cutting: Provides stable and consistent high grinding cutting force. ※ Sandpaper is only sharp at the start of grinding, after which its sharpness declines linearly.
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.
