Product Description
Cuting is the first step in material analysis, and the selection of the cutting ...
In the manufacturing of drill bits and cutting tools, metallographic inspection of metal powders prior to sintering serves as the fundamental guarantee for quality control. By preparing and observing raw powder samples, the internal microstructure can be directly evaluated—including the degree of pre-alloying, morphology of primary carbides, and purity—thus predicting the uniformity of the sintered structure.
This inspection effectively identifies potential defects such as compositional segregation, carbide agglomeration, and inclusions, thereby mitigating the risks of insufficient wear resistance or premature failure in subsequent products from the material source. Combined with metallographic analysis of sintered finished products, the two form a complete quality verification loop covering powder characteristics to final performance, providing a consistent scientific basis and reliable guarantee for manufacturing high-performance drill bits and cutting tools.
Below is the sample preparation protocol for this test:
1️⃣ Grinding Step 1: P1200 abrasive paper
2️⃣ Grinding Step 2: P2000 abrasive paper
3️⃣ Rough Polishing: CS-JP + 3 μm PD-WT polycrystalline diamond
4️⃣ Fine Polishing: ZN-JP + 50 nm SO-T401 silica
