Introduction Of Several Kinds Of Diamond Grinding Wheel Abrasives

1. Chromium Steel Jade (Crystalline Chromium Steel)

Chromium steel jade is an abrasive with a hardness similar to white corundum but better toughness (between brown corundum and white corundum). As a result, the grinding efficiency and durability of a grinding wheel using chromium steel jade as the abrasive are higher than those using white corundum. Additionally, the abrasive cutting edge on the grinding wheel's surface can maintain its shape for an extended period after trimming.

This makes chromium steel jade an ideal abrasive for grinding hardened high-strength steel, measuring tools, and instrument parts requiring high finish quality. It is also suitable for forming grinding and cutting tools. Due to its superior durability, chromium steel jade is priced higher and should mainly be used for fine grinding in high-precision applications.

• Applications: Hardened high-strength steel, measuring tools, and instrument parts
• Ideal For: Fine grinding, high finish requirements

2. Single Crystal Corundum (GD) and Microcrystalline Corundum (GW)

• Single Crystal Corundum (GD): This abrasive is known for its high hardness, excellent toughness, and good resistance to crushing during grinding. It is commonly used for grinding stainless steel and high-speed steel, especially in high-hardness steel grinding applications. Single-crystal corundum delivers high precision and excellent cutting performance.
• Microcrystalline Corundum (GW): This abrasive is even tougher than single-crystal corundum, with better self-sharpening properties. It is ideal for grinding materials such as stainless steel, bearing steel, and special nodular cast iron. Microcrystalline corundum can also be used for high-finish grinding.
• Applications: Stainless steel, bearing steel, high-speed steel, and high-hardness materials
• Ideal For: High finish grinding, high-hardness steel, and steel with complex hardness profiles

3. Black Silicon Carbide Abrasive

Black silicon carbide is characterized by its sharp, water chestnut-shaped abrasive grains. It is known for its high hardness, even higher than that of corundum abrasives. However, it has low toughness and can easily break under high cutting pressure. Therefore, black silicon carbide is best suited for grinding soft materials or materials with low tensile strength.

• Applications: Soft materials, non-ferrous metals, and low-strength materials
• Ideal For: Grinding soft materials like plastics and aluminum, as well as materials with low tensile strength

4. Green Silicon Carbide Abrasive

Green silicon carbide has a similar hardness to black silicon carbide, but it is more brittle. This abrasive is primarily used for grinding cemented carbide, brittle materials such as optical glass, and other high-precision materials. Green silicon carbide is often used for fine grinding and high-precision polishing due to its excellent cutting ability and sharp edges.

• Applications: Cemented carbide, optical glass, brittle materials
• Ideal For: High-precision grinding, fine grinding, and polishing of brittle materials

5. Diamond Abrasive

Diamond is the hardest known material, offering superior cutting performance. It is used for processing materials with extremely high hardness that cannot be easily processed by other abrasives. Diamond grinding wheels made from diamond abrasives have exceptional performance compared to those made with corundum and silicon carbide abrasives.

Although diamond grinding wheels are expensive, they are indispensable for grinding hard materials like ceramics, hard alloys, and superalloys. Their unique ability to maintain sharpness and cutting ability makes them ideal for precision work in the most demanding applications.

• Applications: Hard metals, ceramics, gemstones, and superhard materials
• Ideal For: Precision grinding, high-hardness materials, and industrial grinding
