A large manufacturing shop recently purchased a high speed band saw to cut aluminum. It was equipped with a mechanical rotating brush system to clean the blade as it ran, but this was unable to keep up with the volume of coolant-soaked chips that were produced at higher speeds. They had two options:
*Run the saw at a slower speed (and actually, their production schedule would not allow this, so technically there was only one option…)
*Come up with a reliable method of cleaning the saw blade (this is where EXAIR comes in.)
The Maintenance Supervisor was familiar with the capabilities of the Super Air Knife from past career experience, so he got two Model 110003 3″ Aluminum Super Air Knives installed:
This has made a “night-and-day” difference for this sawing operation:
*In the first week they had the saw, they went through four saw blades…when the teeth get clogged with chips, they don’t cut right; they get hot; and they fail.
*The inability of the brush system to remove the chips caused them to accumulate in the belt pulley housings…operators were spending 2-3 hours A DAY just to shut down the saw and clean them out.
*The excess of chips also caused the blade’s guide bearings to fail, which caused almost a day’s worth of down time to replace.
*The Maintenance Supervisor was called to the saw repeatedly during the work day to address these, and many other minor, malfunctions due to the inability to remove the chips.
This saw is now operating at the capacity they intended when they purchased it. All for about $400, and that includes the door hinge they used to install it and allow for precise positioning (how cool is that?)
