This part illustrates well the quality after laser cutting. When cutting 15mm thick steel with 5kW Trumpf Trulaser machine the surface is ready for enduse.
The cutting speed is 1500mm / 6 min. Before surface treatment an oxidfilm removal is recommended, the result can be seen on the photo and the film.
One of the part is before, the other one is after the removal. For mechanical engineering and structure construction this is a perfect quality!
