Are Ceramic Sanding Belts Better?
Abrasives have a big impact on the performance and efficiency of metal grinding applications. The best abrasives are designed to make the job easier and faster, while also producing quality results that last for longer periods of time.
There are a lot of different abrasive materials out there, but the most important ones to know about are aluminum oxide, silicon carbide, and zirconia. Each has its own unique advantages and drawbacks, and a little research can help you choose the right one for your needs.
How To Pick An Abrasive
Abrasives come in a variety of grit sizes and are available in bi-directional or closed-coated abrasive belts. The choice of abrasive type and grit size is key to finding the right abrasive for your job, as they determine how fast you can cut and how long you can work before the abrasive breaks down.
How to Select the Best Sanding Belt For Your Application
There are many factors to consider when choosing a sanding belt, including the grit size you want, your budget, and the material that will be used. Taking these factors into account will ensure that you get the most out of your abrasive and your sanding machine.
Grit Sizes for Knife Making
There is no one size that will suit all knife makers, so you’ll need to find the grit size that works for your particular application. For example, if you’re a professional knife maker, you may choose to use fine grits (P180 – P800) to hone and sharpen the blade, or ultra-fine grits (P1000 – P5000) to create a sleek, smooth finish at the end of the process.
How to Choose a Sanding Belt Backing
If you plan on sanding hard surfaces, choose an abrasive that can withstand high temperatures and pressure. For example, aluminum oxide is a great option for sanding hard wood or steel because it can take high levels of heat and pressure while also offering excellent sanding results.
Likewise, zirconia is an excellent choice for metal applications due to its ability to resist high temperatures and pressure while providing exceptional sanding results. This makes it the ideal abrasive for knife-making kits, steel fabrication shops, and other industrial and commercial uses.
The abrasive you choose should also be compatible with your sanding machine and your project’s requirements, so be sure to check the abrasive’s manufacturer’s recommendations. For instance, if you’re using an aluminum oxide sanding belt in a wide-belt sander, you should look for a belt with a closed-coat abrasive coating to reduce the risk of overheating and damage to your machine.
Alternatively, if you’re working on soft or wood surfaces, an abrasive with a closed-coat coating is a good choice because it won’t clog your machine or create an uneven surface. For harder, non-ferrous materials like aluminum, stainless steel, or titanium alloys, you’ll need a more aggressive abrasive that can handle high pressure and heat while sanding. For these types of projects, you’ll need to invest in a more premium abrasive, such as ceramic or zirconia.
