Illustration of Friction sawing

The process

The workpiece is clamped and processed by a blade which is usually provided with non-cutting teeth. The friction between the blade and workpiece allows the material to be heated, softened, allowing the blade to remove and cut material.

Advantages and disadvantages
In comparison with alternative methods
Very hard materials can be cut, very thin materials can be cut, thin materials that can damage the saw teeth can easily be cut
Extended service life of saw blades with the opportunity to work with dull blades
Uneven degrees
Possibility of hardening around cuts
Requires a lot of experience
