bandsaw

A bandsaw is a power saw that uses a long, continuous loop of toothed steel blade stretched between wheels to cut material. The blade runs around two or more wheels in a single plane, typically with a table or supporting surface for the workpiece. Bandsaws are valued for their ability to make curved cuts as well as straight cuts, and for resawing thick stock into thinner slabs.

There are several common configurations. Horizontal bandsaws are typically used in metalworking for producing straight cuts on large or thick stock, with the work fed into a stationary blade. Vertical bandsaws place the blade in a vertical plane and are widely used in woodworking and smaller metalwork; the table can tilt to accommodate bevel cuts and complex shapes. Portable bandsaws offer mobility for field or shop use. Some machines combine features to handle both metal and wood with adjustable tension, blade guides, and variable speeds.

Key components include the drive wheel, an idler wheel, the blade, a blade tensioning and tracking system, upper and lower blade guides, and a worktable. In metalworking models, a feed mechanism and cutting fluid may be provided. The operator selects a blade width, adjusts tension and tracking, positions fences or guides, and feeds the work at a controlled rate to produce the desired cut.

Uses and advantages: bandsaws are used in woodworking for curves, veneers, and resawing, and in metalworking for straight or shaped cuts in stock and for intricate patterns. Safety practices include using blade guards, securing work, keeping fingers away from the blade, and turning off and unplugging the machine when changing blades. Regular maintenance focuses on blade sharpness, tension, tracking, and cleaning.
