The cutting technology named by us after Contact Line (CL) is the usual procedure for all band saws. Here, there is a line-like contact between cutting band and sample. This simple method is sufficient for a number of applications. However, in conparision to the contact point (CP) method, this method generates more friction due to the larger contact area between the cutting band and the sample. Higher feed forces are required for the cutting process and this results in higher thermal and mechanical stress applied to the sample. A lower surface quality and even structural damages can be the result. Furthermore, the cutting band will wear more quickly, too.
In contrast, the cutting technology named by us after Contact Point (CP) only shows a point-like contact between cutting band and sample. This is achieved by a especially designed, servo driven clamping fixture which is oscillating the sample in a rotary movement. Osciallating speed as well as the swing can be adjusted. This technology guarantess higher cutting speed, a superior quality of the cutted surface and less wear of the cutting band.
