Freewheel saw i.e. mechanical fret saw, for sectioning e.g. metal, during creation of models in carpenter's metal workshop, has saw blades movable in all directions, where electromotor is utilized to obtain specific drive power in saw

摘要

The saw has saw blades (2.2) movable in all directions, where the saw is swivelable or rotatable around 360 degrees. An electromotor of country-specific variation is utilized to obtain specific drive power in the saw. A tool clamp-saw blade clamping apparatus is supported in a sliding manner and guided in a swivelable or rotatable manner around 360 degrees. A mold shaft (2.4) i.e. multi-edge shaft, is anchored between a lower axial bearing unit (2.8) and an upper traction rope (1.2) i.e. steel rope. A fan device removes material particles from a workpiece.
