What sizes do sanding belts come in?
Sanding belts are available in a variety of sizes from ¼” x 18” all the way up to 60” x 360” and beyond (popular sizes include 2 x 72, 2 x 42, 1 x 30, 2 x 48, 3 x 18, 4 x 36, and 4 x 24).
What is the most common belt size for a belt sander?
Hand Powered Belt Sander The most common sized belts used on Hand Sanders are 3” x 21”, 3” x 18” and 4” x 24″ sanding belts.
What are wide belt sanders used for?
The wide belt sander is used to machine stock flat and to specific thicknesses. It can be used with solid wood and composite boards such as plywood and MDF. A rubber conveyor carries your stock through the machine while a wide abrasive belt removes material from the top surface.
Do I need a wide belt sander?
The right one for you will depend on your application. If you need to even out a long wooden board, a planer will get the job done fast. On the other hand, if you want to strip away coatings, or make a surface smoother, a wide belt sander will be the better investment.
How much material can a wide belt sander remove?
With a three-head sander you can run a grit sequence of 100-150-180 and remove approximately 1/32 inch in one pass. To determine how many heads you require, you need to know how much stock you need to remove and what is your final grit finish.
How tight should a sanding belt be?
Most wood sanding applications require a belt tension near 40 psi. Because the goal is to keep the belt from slipping, users sometimes err on the side of using too much belt tension. Several problems can result from excessive belt tension.
Why does my belt sander keep breaking belts?
Too Much Pressure on the Belt Sander During Use If you run your belt sander with too much or too little tension pressure, you may experience tracking issues, belt folding, belt tearing, and joint failure. Your belt’s ideal tension pressure will depend on whether it has a paper, cloth, or polyester backing.
What are the best sanding belts for steel?
As high-performance belts, both zirconia and ceramic sanding belts will last longer and remove metal faster than aluminum oxide or silicon carbide sanding belts. Both belts have the ability to resharpen as they wear and both are primarily used on metal applications. In the end, both types of belts are excellent belts.
Is zirconium harder than aluminum oxide?
Zirconia grain has a high heat resistance and is substantially stronger than aluminum oxide abrasives, which makes it a good choice for high-pressure grinding and machining applications. Zirconia belts, which work best in the 24 to 120 grit range, are regularly used in steel fabrication shops.
How much wood can you sand off each pass through the wide belt sander?
As mentioned earlier, abrasive belts can only remove a certain amount of stock dependent on grit size. With a three-head sander you can run a grit sequence of 100-150-180 and remove approximately 1/32 inch in one pass.
Why do my sanding belts keep snapping?
If your belt popped, it might have been due to excessive loading of the material being sanded. Occasionally, particles caught in the machine or a wide variation in the thickness of the workpiece can cause too much pressure and snap the belt.
