A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.
A band saw for work pieces (1) made of stone and other materials, comprising a workpiece table (2) to which at least one workpiece (1) can be fixed, and a tool support for a continuous saw blade (3), the workpiece (1) and the saw blade (3) being supported for translational motions and tilting motions about an axis perpendicular to a cutting plane relative to one another, said motions being coordinated such that a crooked cut is made at a blade contact area in the workpiece as the workpiece is being cut, the crooked cut results in the blade contact area of the saw blade being less than a thickness of the material being engaged by the blade and defines a non-linear cutting path through the thickness of the material, with geometric parameters of the cutting path at the blade contact area being continuously variable.
