With plasma cutting technique from our company, very good cutting results can be achieved. But how good are they really? The answer lies in the DIN EN ISO 9013*. Thanks to specified parameters, the quality of cut surfaces can be evaluated independent of the thermal cutting process used.
The quality of cut surfaces when using thermal cutting processes is determined by the
|
rectangularity or inclination tolerance and
|
|
|
the average surface roughness.
|
|
Additionally,
|
the groove lag,
|
|
|
the initial fusing of the upper edge and
|
|
|
possible dross or drop formation at the bottom cutting edge
|
|
of the work-piece can be considered.
According to the standards, the results are divided into different categories. The precision decreases from category 1 to category 5. The cutting quality with laser ranks between categories 2 and 4, whereas standard plasma cutting ranks in category 5. Thanks to the state-of-the-art HiFocus/PLUS technology, Kjellberg Finsterwalde's systems allow much preciser cutting and nearly vertical cut surfaces so that the results also rank betweeen categories 2 and 4. The usual deviations amount to approx. 2°. The precision of the plasma cuts is basically influenced by the interaction of the plasma cutting unit with the guiding system and the height control unit. The cutting speed, too, affects the inclination of the cut surfaces.
