Band Cutting Machine
Band saws are common in most woodworking shops. A band with cutting teeth that operates in a big circle used for cutting almost any shape. They are ideal tools for cutting irregular shapes, with the curved cuts made by the tool determined by the width of the band blade used during its operation.
Band saws are fixed power tools and don’t come handheld, though miniature varieties exist. They successfully operate utilizing a band fitted with toothed metal blades, which ride on two wheels on a vertical plane. The wheels are powered by a motor, which facilitates the revolving of the bands. The wheels are adjustable in most band saws, and the space made between the wheels often helps in dictating the cut types the band saw would make.
Most timber mills prefer using band saws over circular saws since wastage isn’t an issue with band saws. As band saws leave behind a smaller kerf, which in the realm of woodworking means a saw’s cut size, lesser waste comes from using it.
Band Saw Blade
The band saw’s blades in timber mills are often stretched very tight, considering the large chunks of wood they are given to cut up. With blade sizes ranging from 4” wide x 19’ long x 22 GA thickness to 16” wide x 62’ long x 11 GA thickness, large band saws fit the bill for timber yards’ needs when it comes to cutting.
There are different types of large band saws, the most common of which are Head Saws, Double Cut Saws, Resaws.
Large bandsaws that make the first cuts in a log are called a head saw. They have a 2-3 inch tooth space on the cutting edge and teeth on the back are silver. The silver teeth are designed to wipe out slivers when the blade needs to be backed out and are noncutting.
Double Cut Saws
As the name implies the band saw blade has cutting teeth on both sides of the blade. They are similar in size to a head saw and are geared to work the same only they have the ability to cut backward.
A resaw is a large bandsaw optimized for cutting timber along the grain to reduce larger sections into smaller sections or veneers. Resawing veneers requires a wide blade—commonly 2 to 3 in (51 to 76 mm)—with a small kerf to minimize waste. Resaw blades of up to 1 in (25 mm) may be fitted to a standard bandsaw.
Bottom line, band saws are generally useful for overall cutting work, and not for detail cutting. They are pretty much the initial phase tools for a woodworking excursion, giving woodworkers wood pieces on which, they could do more detailed work on.
