A friction saw blade is a type of saw blade designed for high-speed cutting that relies on heat generated by friction to soften the material being cut.
Unlike cold cutting saw blades that remove material with sharp teeth through direct shearing, friction saw blades generate intense heat by rotating at extremely high speeds. This heat softens the material, allowing the blade to "melt" or "burn" its way through. This process is also known as hot friction cutting.
Here's a breakdown of key characteristics:
- High Speed: Friction saw blades operate at much higher speeds than traditional saw blades.
- Heat Generation: The primary cutting mechanism is the heat produced by friction between the blade and the workpiece.
- Material Softening: The intense heat softens the material, enabling the blade to pass through it.
- Cutting Process: The cutting process is often described as "melting" or "burning" through the material.
- Application: Typically used for cutting ferrous metals like steel.
In summary, a friction saw blade uses rapid rotational speed to generate heat, softening the target material and allowing the blade to cut through it, distinguishing it from methods that rely solely on shearing.
