A band saw is a saw with a prolonged sharp blade that consists of a continuous band of toothed metal stretched between two separate wheels to cut materials. The band saw is basically used in woodworking, lumbering, metalworking and several other materials used.
Most band saws possess two wheels going round the same plane where one of the wheels is powered, though some may have about three or four in order of distributing the load. The blade itself can also come with several or numerous different sizes and tooth pitches like in the case of teeth per inch or TPI, according to Sawinery. This enables the machine to work in different aspects and also has the capability to cut variety of materials such as woods, metal and plastic.
It should be noted that almost all band saws in the present world are powered by an electric motor. Line shaft versions were once famous in the market but presently they are now antiques.
TYPES OF BAND SAWS
We have different types of band saws that individuals currently use for different purposes. Precisely, we have about five types of band saws and they will be briefly explained and listed below as follows;
Most workshops in residential basements or garages contain small or sometimes, medium sized band saws that has the ability to cut woods, metal or plastic. In several cases, a general purpose blade is abandoned in place, though blades characterized for wood or metal can be turned out when volume of use warrants.
Most residential and commercial band saws exhibit a shape of vertical type mounted on a bench or a cabinet stand.
Saws specifically meant for cutting meat are usually made of stainless steel construction with simple to clean features. The blades either have a plain/ scalloped knife edges or a fine teeth with heated treated tips.
Timber mills make use of large band saws for ripping lumber, most at times they are preferred over circular saws for ripping because they can suit large diameter timber.
There are also small portable sawmills that consists of a shop size band saw placed on a protected table, which are called band saw mills.
Head saws are usually known to be large band saws that make the initial or opening cuts in a log. In general terms, they have between 2 to 3 (51 to 76 mm) tooth space on the cutting edge and silver teeth on the remote of it. Silver teeth are non cutting teeth created to eliminate silvers out of the way when the blade requires being back out of a cut.
A resaw is a large band saw enhanced for cutting timber along the grain in order of reducing huge sections into fewer sections or veneers. Resawing sections needs a wide blade that is between the range of 2 to3 in (51 to 76 mm) with a small kerf to reduce waste. Resaw blades are usually up to 1 in (25 mm) which may be fitted to a usable band saw.
