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.
Resaw blades used in a sawmill. A resaw is a large band saw 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 inches (52–78 mm) – with a small kerf to minimize waste. Resaw blades of up to 1 inch (26 mm) may be fitted to a ...
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
The ringsaw blade in comparison may be made rigid, thus stronger and less flexible under cutting loads, giving a more accurate cut. Some make a particular feature of the ring saw's ability to cut forwards, backwards and sideways. [3] As the bandsaw blade must be flexible enough to pass around the wheels, its blades are limited to cutting on the ...
The whole saw blade is made of High-Speed Steel (HSS). HSS saw blades are mainly used to cut steel, copper, aluminum and other metal materials. If high-strength steels (e.g., stainless steel) are to be cut, the blades made of cobalt HSS (e.g. M35, M42) should be used. Tungsten carbide
Saw blade "grabbing" occurs more frequently during ripping than cross-cutting (cuts made to wood or stone across its main grain or axis). It can occur with both hand saws and bandsaws but is more dangerous with a circular saw as areas of the circular blade close to the cutting area are moving in different directions. If a bandsaw grabs, the ...
