• the sawing cable is not guided accurately and thus no accurate cut can be performed. Since the sawing wire is also guided around sharp edges in the inlet region in the workpiece or in the exit region of the workpiece, it is subject to increased wear, especially at the gate of the workpiece. In this case, there is an increased risk of injury due to cable breakage, in which a relatively long section of the sawing cable - in particular from the exit area of the

• Wire saw increases the reliability in several ways. Since the sawing wire is guided to the workpiece and works on rope pressure - and is no longer guided by a hole around sharp edges on train - the risk is significantly lower that the sawing wire breaks. Even if the sawing wire were to break, a pronounced "whiplash effect" would not occur, as described above, since due to the guiding device only one could strike down significantly shorter section of the saw, which is why the safety zone to be observed around the wire saw is considerably smaller.
