Q:. I recently bought a new belt sander and a supply of new belts. A:. Belt seams rarely fail, despite the friction and high-speed flexing that sanding belts endure. To rule out belt age as a possible problem, purchase what you expect to use within eight months to a year and store unused belts in a temperature-controlled place.
It can be incredibly frustrating when you pay good money for sanding belts then they break at some point of the process of using them. Paper belts are much more fragile than cloth backed belts and thus are prone to breakage. Going to a cloth backed sanding belt will prevent creases, tears and breakage in many situations.
07-09-2006, 9:37 PM #1 sanding belts breaking I think I might have set a record tonight……. 15 sanding belts snapped while in use, one after another. I remember reading somewhere that the adhesive used to join sanding belts will deteriorate after a period of time, and I suppose that is what happened here. After a few breaks with these, I figured that it was just going to keep happening, so I turned the speed to the lowest and kept on sanding, breaking belt, sanding, breaking belt etc.
Trying to diagnose and isolate the root causes for wide belt sander issues can be extremely difficult. In light of this difficulty, the abrasive technicians at Fintech Industrial Abrasives have compiled a list of the most common wide belt sander issues and their respective potential fixes. Constantly running workpieces through the sander in the same place on the belt can quickly wear out that portion of the belt and lead to loading and belt burning.
why do my belt sander belts keep breaking Related Question:
How much tension should a belt sander have?
Most wood sanding applications (such as mould sanding using narrow cloth belts) require a belt tension of approximately 40 psi. However, there are some special exceptions. For example, abrasive planing operations using coarse grits typically demand belt tension in the range of 70 to 90 psi.
How can I make my sanding belt last longer?
Another way to extend the life of your belts is to prevent clogging and loading in the first place. This can be done with an abrasive belt grease stick that goes on the belt before use. These sticks have a lightweight grease that spreads a thin layer of lubricant over the surface of your sanding material.
How do you adjust the tension on a belt sander?
If the belt is shifting toward the side of the sander that the knob is on, then loosen the knob by turning it about half a turn counterclockwise. If the belt is shifting away from the side of the sander that the knob is on, tighten the knob by turning it about half a turn clockwise.
Can sanding belts be repaired?
You can also mend or make abrasive belts by this DIY method: Obtain some bias binding tape from a fabric store, or you can make your own. Then use CA adhesive to bind the bias binding tape to the cleaned edges of the sanding belt you want to make or repair. I have done this many times, and it works fine.
How long does sandpaper on a belt sander last?
The sander’s rotating power can also impact how long the sandpaper will last. For example, using it on a 1095 blade can make your sandpaper last for over a month. Instead, if using it on an S110V, it can last only a few hours.
What type of glue is used to make sanding belts?
Lay one end of the belt, grit-side down, on the bench; then apply cyanoacrylate glue to the end of the belt. Lay half of the bias tape’s width on the glue, place waxed paper over the tape, and use a weight to press down on it for about 30 seconds, or until the glue sets.
What tape is used on sanding belts?
Apply the Scotch 8959 tape by using a small piece of swimming pool noodle or other firm foam/rubber like a squeegee pressing firmly and leaving overlap on both ends, make sure there are no air bubbles and the tape is perfectly flat covering both splice ends equally.
Can you cut sanding belts?
You can cut sanding strips from sanding rolls or sanding belts. Cutting from sanding rolls is the more ideal solution. The key is to trim the leading edge so that the angled edge matches the drum circumference.
