MECAL SW 451 back-cut mitre saw

The Mecal “SW 451” is a back cut saw to cut  straight and miter PVC and aluminum profiles. The blade is activated by means of an hydro-pneumatic cylinder. The operator holds the two push buttons until the cut is completed. As soon as one or both buttons are released, the blade retract in its own housing.

GENERAL

The Mecal “SW 451” is a back-cut aluminum mitre saw ideal for applications such as residential and commercial windows, railings as well as industrial aluminum profile cutting requiring mitre cutting. The saw can cut straight or mitre both on vinyl or aluminum extrusions.

An hydro-pneumatic cylinder ensures the precise and uniform feed speed of the blade. Two pneumatic horizontal cylinders hold the extrusion firm in place for the maximum precision of the cut. The “SW 451” features a tilting head capable to cut mitre angles ± 45° both right and left. Intermediate angles are also possible by adjusting intermediate mechanical stops.

OPERATION

To perform the cut, the operator must hold simultaneously two pushbuttons with both hands. As soon as the cut is performed and one button is released, the blade retract in its own housing.
