Selecting a sanding belt for your metal finishing application can be difficult given the sheer amount of choice available. With so many grit sizes, abrasive types, and backing materials on the belts, which one delivers the most reliable performance when working with metals?
Although most abrasives can be used for applications involving metal (it’s highly advised that open coat aluminum oxide not be used for metal finishing), ceramic belts are widely recognized for their superior performance and results. As a result, they have an equally premium price, which is why we are often asked if ceramic belts are really the best abrasive for metal finishing.
The answer is yes, and in this blog, we’ll explain why ceramic belts are worth the cost and how they can save you money.
Ceramic is a high-performance grain. It has a closed-coat composition, with the grain being applied evenly without any voids in the surface to ensure a consistent finish. It also has an aggressive cutting ability, and microcrystalline structure that creates sharp new cutting edges with each use, resulting in a longer working life compared to most other abrasives. The ability to maintain a fast and durable cutting action makes it an ideal abrasive for preparing metal surfaces and stock removal, as well as restoring and finishing workpieces.
Ceramic abrasives require considerable pressure and speed to fracture the grain and reveal fresh cutting surfaces. Without enough pressure, a ceramic belt can become “glazed” and will stop cutting even though there is grit left. This issue is easily fixed by finding a scrap piece of steel and applying hard pressure to the belt at a high speed. Don’t worry, the stearate topcoat helps to mitigate heat build up.
For years, ceramic belts have been used to apply a smooth finish in the applications like the following:
At Red Label Abrasives, we manufacture and sell resin-bonded ceramic sanding belts that outlast other abrasives while providing a faster and cooler finishing job. EdgeCore ceramic, our newest sanding technology, evenly micro-fractures during use and maintains cool grinding temperatures, even during high-speed grinding.
Ceramic is generally sold in 24 through 120 grit with an X-weight backing, but Red Label Abrasives also makes it available in 180, 240, 320, and 400 grit with a J-weight backing, so that you have the fine grits needed to deliver a superior finish on your metal products.
