Product Selection Differences for Polycrystalline Abrasives

When selecting Polycrystalline Abrasives, there are several key differences to consider:

1. Crystal Structure: Polycrystalline abrasives can have different crystal structures, such as diamond or cubic boron nitride (CBN). Diamond abrasive grains are typically used for grinding non-ferrous materials, while CBN grains are better suited for ferrous materials.

2. Hardness: The hardness of the abrasive material will determine its effectiveness in grinding and cutting operations. Diamond abrasives are known for their exceptional hardness, making them suitable for grinding hard materials like carbides and ceramics.

3. Wear Resistance: Consider the wear resistance of the abrasive material to ensure longer tool life and consistent performance over time.

4. Grain Size: The size of the abrasive grains will affect the surface finish and material removal rate. Finer grains are suitable for precision grinding applications, while coarser grains are better for heavy material removal.

5. Bonding Material: The bonding material used in polycrystalline abrasives can vary and impact the overall performance of the abrasive tool. Common bonding materials include metal, resin, vitrified, and electroplated bonds.

6. Application: Different types of polycrystalline abrasives are optimized for specific applications, such as cutting, grinding, or polishing. Consider the intended use of the abrasive material when making your selection.

7. Cost: Cost is also an important factor to consider when selecting polycrystalline abrasives. Higher-quality abrasives may have a higher upfront cost but can provide better performance and longer tool life.

By evaluating these key differences and considering your specific needs and requirements, you can choose the most suitable polycrystalline abrasive for your application.
