Bandsagen

Bandsagen, commonly known as the bandsaw in English, is a power saw that uses a long, continuous toothed blade stretched between two or more wheels. The blade travels in a loop and is guided by adjustable blade guides and a worktable or frame, allowing a stable, controlled cut. Most bandsaws are vertical, with the blade rising through the worktable to cut stock supported on the table, while horizontal bandsaws are used for metal cutting and larger stock.

The blade width, tooth pitch, and geometry determine cutting performance: narrow blades excel at tight curves and intricate shapes, while wider blades are better for straight cuts and resawing thick stock. Bandsaws can perform straight cuts, curves, and resawing, and many models include fences and adjustable guides to improve accuracy. The machine may be powered by electric motors with varying speeds, and blades are chosen to suit the material and task.

In woodworking, bandsaws enable pattern work, curve cutting, veneer production, and safe handling of irregular shapes. In metalworking, bandsaws are used to cut steel, aluminum, and other metals, often with coolant and higher feed rates on appropriate machines. The availability of vertical and horizontal configurations allows bandsaws to serve different production needs, from small shops to larger fabrication facilities.

History: The bandsaw was developed in the 19th century and gradually became a standard tool in both carpentry and metal fabrication, with continual improvements in blade guides, tensioning systems, and motor designs over time.

Safety and maintenance: Users should ensure blade guards and guides are properly set, keep fingers away from the moving blade, use clamps or push tools as needed, and regularly check blade tension, tracking, and alignment. Protective eyewear and hearing protection are recommended where appropriate.
