Bandsaws are used for woodworking, metalworking, or for cutting a variety of other materials. They were originally designed for cutting irregular or curved shapes, though they certainly can make straight cuts. It took some time, however, for the technology to catch up to the vision. And the “hard part” has always been the blades.
The idea of the bandsaw dates back to at least 1809, when William Newberry received the first known British patent for the idea. But actual bandsaws remained impractical because of the blades. Constant flexing of the bandsaw blade over the bandsaw wheels caused the material or the welded joint of the blade to quickly fail, keeping the idea theoretical for decades.
Nearly 40 years passed before a French woman, Anne Paulin Crepin, devised a technique for welding a bandsaw blade so that it could withstand the rigors of sawing and bending around bandsaw wheels. She applied for a patent in 1846, and soon afterward the manufacturer A. Perin & Company of Paris, France purchased the rights to her innovation. Combining Crepin’s welding method with new steel alloys and advanced tempering techniques, Perin created the first modern bandsaw blade.
Power hacksaws (with reciprocating blades) were once common in the metalworking industries, but bandsaws and cold saws have mostly displaced them.
Choosing the right bandsaw blade depends on many factors; including type of bandsaw, condition of bandsaw, what material is to be cut, and how the material will be cut. It is impossible for one blade to work well for every purpose. Some applications need special blades for best results, and L.A Grinding Company has a state of the art welding center capable of making custom welded-to-length bandsaw blades for most applications. Bandsaws can be custom ordered and made while you wait (between the hours of 8 AM – 3PM).
