5 axis CNC Bridge Saw BK5
available with 4 or 5 axes
This machine is a fully interpolated 4- or 5-axis bridge saw with automatic tilting 0° to 90° (BK4 head tilts 0° to 45° manually).
The first “green” machine in the stone market, “green” standing for: Energy efficiency, Quality, Durability, Costs.
The BK machines do the same job and more of a traditional bridge saw with only 25% of the energy.
They are 30% the size of a traditional bridge saw, but keep or exceed the same working area;
The X axis of the BK machine is moved by two motors on a gantry that home independently, assuring a perfect square every time.
The hydraulic table tilts to 85 degrees allowing easy loading of the slabs to cut.
The user interface facilitates the interaction between the operator and the machine: it is easy to set up simple linear cuts and to cut any complex shape (rectangles, ovals, arcs, etc.) imported from DXF files.
The machine is equipped with a point laser to copy 2D templates and save them in DXF format.
This machine is out of production from September 2016. Please click here to see the new BK2020.
