Metal sanding belts are produced using ceramic, zirconia, aluminum oxide, and silicon carbide abrasives grains. It is stated that ceramic and zirconia abrasives grains work best for sanding metals. Durability-wise, they both outperform silicon carbide and aluminum oxide. This article covers all aspects of ceramic belts and their applications.
Ceramic alumina grains or sanding belts have the highest cut rate and the longest life of abrasive grains. They represent a revolution in the machining industry. You can cut ceramic abrasive grains steadily and forcefully. With moderate to high-pressure, Ceramic is orange or red. Used mostly in metalworking-related applications. Grits ranging from 24 to 120 are commonly used in ceramic abrasives. Although possessing a finer micro-crystalline structure than aluminum oxide or zirconia abrasive grains, ceramic abrasive grains are far more sensitive to heat and temperature.
Ceramic abrasive grains are used to make a wide variety of abrasive devices. Tools with ceramic grain coatings are employed for grinding, deburring, sanding, removing heavy stock, and treating metal surfaces. Titanium alloys, mild steel mill scales, stainless steel finishing, aluminum castings, and ceramic abrasives are all used in the aerospace industry.
Ceramic sander belts significantly improve metal grinding applications. They are widely used to finish high-carbon steel in the knife business. Compared to other abrasive grain types, ceramic abrasives offer the longest lifespan and fastest cutting speed. Its micro-crystalline habit and more homogeneous structure than zirconia allow them to degrade more rapidly and be employed in a wider range of applications, such as:
Because they separate into smaller pieces during grinding, ceramic sanding belts have a longer performance life than other abrasive grains. In contrast to zirconia, ceramics are very sensitive to heat and pressure; hence, you must properly develop their use in such applications.
