Tension, in the context of band saw blades or other cutting tools, refers to the force applied to the blade to maintain its proper shape and alignment during cutting operations. Proper blade tension is crucial for ensuring accurate, consistent cutting performance, minimizing blade deflection, and reducing the risk of blade breakage or premature wear. Tension can be adjusted using a tensioning mechanism, such as a spring-loaded knob or lever, and should be set according to the blade manufacturer’s recommendations.
