White Fused Alumina Grinding Wheels

White fused alumina grinding wheel is a kind of artificial abrasive made of high-purity aluminum oxide (Al₂O₃) as the main raw material, which is made by high-temperature electric melting crystallization. It is made into a grinding wheel through binder pressing and sintering process. It is widely used in fine grinding and dry grinding of hard metals, alloy steel, stainless steel, carbon steel and other materials.

High Hardness
The Mohs hardness of white fused alumina grinding wheel can reach more than 9, and it has strong cutting ability. When processing high-hardness materials such as alloy steel, stainless steel or high-carbon steel, the metal removal rate per unit time can reach 20~35 cm³/min.

Good Self-sharpening
White corundum has a brittle crystal structure and is easy to break naturally during the grinding process to form a new sharp cutting edge. It can remain sharp in the continuous grinding state without frequent trimming, and the replacement cycle is as high as 20~30 hours or more.

No Metal Impurities
White corundum is made of industrial alumina by high-temperature electric melting. The purity of the raw material is as high as 99%. No metal impurities such as iron and sulfur are introduced during the production process, which can avoid chemical reactions such as oxidation, corrosion or surface discoloration caused by metal impurities and workpieces during the grinding process.

Stainless Steel Grinding
White corundum grinding wheels are often used in the external cylindrical grinding and surface grinding of stainless steel parts. They can effectively remove the surface oxide layer and improve the finish of the workpiece.

Tool Grinding
White corundum grinding wheels are suitable for fine grinding and grinding of high-speed steel tools, milling cutters, drill bits, etc., which can maintain sharp edges and improve tool life and cutting performance.

Carbide Surface Finishing
White fused alumina grinding wheels can be used for surface finishing of carbide parts to help remove tiny burrs and dimensional deviations, ensure assembly accuracy and safety of use.

Glass And Ceramic Processing
White fused alumina grinding wheels are suitable for edge finishing and surface polishing of brittle and hard materials such as optical glass lenses and ceramic insulators to ensure the appearance integrity and assembly accuracy of the finished product.

Finishing Of Mold Parts
White corundum grinding wheels are widely used for dimensional trimming of mold parts such as stamping molds and injection molds to improve mold matching accuracy and extend the mold life cycle.

When choosing a suitable White Fused Alumina Grinding Wheel, several factors should be considered.

First, determine the material to be ground. Different materials require different grit sizes and hardness levels of the grinding wheel. For softer materials, a finer grit and softer wheel may be appropriate, while harder materials may need a coarser grit and harder wheel.

Second, consider the grinding operation. If you need a smooth finish, a finer grit wheel is better. For heavy-duty grinding, a coarser grit and stronger wheel is needed.

Third, check the speed rating of the wheel. Make sure it is compatible with the speed of your grinding machine to ensure safety.

Finally, look for a reputable supplier and quality product to ensure durability and performance.
