Let’s go back a bit. The last time band saw blade tech made a giant leap was in the mid-1960s with the introduction of bi-metal technology, it was soon after followed by the establishment of carbide-tipped blades.
It’s been almost 60 years since then, and no huge advancement has happened. Fortunately, we’re heading to a bright future.
Band sawing efficiency is known to be limited before the dawn of bi-metal blades. That type of blade was used to be made completely of high carbon steel since it was bendable enough to survive the stress that’s caused by its winding path around the saw machine’s drive wheels and into and out of the saw blade guides. The demand was the use of a softer, more pliable backing material.
Speaking of band saw, I’d like to give out a shout to these guys for offering state-of-the-art band saws on the market today.
The Future of Band Saw Blades
Good thing new developments have emerged. Now a band saw blade with a tooth design which supplies a larger tooth cross section is available. This kind of blade provides a stronger cutting surface, eliminates tooth strippage, decreases burring, prevents premature failure, creates low vibration, lessens noise, and takes out chips quicker for long life.
What will we expect in the future, though? One thing is for sure: manufacturers are attempting to make enhancements in tooth geometry for better cutting performance.
Just because the last advancement was in the mid-1960s doesn’t mean manufacturers of band saw blades are doing nothing. In fact, they’ve been making developments slowly and steadily for the past years. The progress was quickened in the 1990s, when design technologies like a 3D machining simulation software made a grand entrance. Because of this software, the ability to minimize the lengthy and costly field testing now became possible. With these new devices, innovations like variable tooth set/height forms were optimized, helping everyone get the most out of their band saw blade investments.
