The Mecal “SW 453 Reverse Garda” is a back stroke aluminum double mitre saw ideal for applications such as residential or commercial windows, storefronts, railings as well as industrial aluminum profile cutting. The saw can cut straight or mitre both on vinyl or aluminum extrusions.

The saw features a motorized right head positioning, while the left cutting unit is stationary. Blade feed direction is from back to forward. Cutting units tilt automatically at any angle between 22.5° and 135° by means of pneumatic cylinders even if the adjustment of the tilting angles must be done manually moving a mechanical reference stop .

Possibility to use both 450mm (17¾”) and 500mm (19.7″) saw blades.

Machine is 4m useful cutting length with double head simultaneously, nevertheless with a special function, it is possible to cut oversize lengths up to approximately twice the maximum cut length.

Machine interface features a Windows based Schneider Electric HMI MAGELIS 10” touch screen complete with an USB port and RJ45 Ethernet connection. 


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 blades retract in their housing. Hydro-pneumatic cylinders ensures the precise index of the blades.


The Mecal “SW 453 Reverse Garda” double mitre saw is provided with two lifting covers (one each cutting head) as part of the standard safety features to provide full protection to the operator.
