A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking , metalworking , and lumbering , but may cut a variety of materials.
An image of a Morrill design saw set is found at the introduction of the article. The plunger (also, pin) pushes against the saw tooth when the handles are squeezed together. The other face of the saw tooth rests against an anvil and the whole saw blade is held at the desired angle to the anvil by a stop or rest.
The saw blade's teeth are tipped (via welding) with small pieces of sharp tungsten carbide block. This type of blade is also called TCT (Tungsten Carbide-Tipped) saw blade. Carbide-tipped saw blades are widely used to cut wood, plywood, laminated board, plastic, glass, aluminum and some other metals. Solid-carbide saw blades
Horizontal band knife blades are wider usually 30–60 mm (1.2–2.4 in) wide for foam converting is popular, for leather goods 40–50 mm (1.6–2.0 in) wide blade is popular, 85–110 mm (3.3–4.3 in) width is popular for the tannery splitting band knife. There are other widths depending on the machine manufacturer.
All sawmills use ripsaws of various types including the circular saw and band saw. Historically sawmills used one or more reciprocating saws more specifically known as an "up-and-down" or "upright saw" which are of two basic types, the frame saw or a muley (mulay) saw [2] which is similar to the hand powered pit saw. Some sawmills also use ...
They are suited to sharpening saw blades and dressing tool edges, especially where a finer, sharper edge or smoother surface finish is desired. The Chainsaw file is one example, used primarily for sharpening chainsaws. These appear to have a round cross-section, but are actually shaped to fit snugly against the cutting edge of a chainsaw's teeth.
Hacksaw blades are normally quite brittle, so care needs to be taken to prevent brittle fracture of the blade. Early blades were of carbon steel, now termed 'low alloy' blades, and were relatively soft and flexible. They avoided breakage, but also wore out rapidly. Except where cost is a particular concern, this type is now obsolete.
Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools).They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).
