Advantage to milling motors: No tools are required and cutting can be performed at higher speed. 

The Hi-Focus version shows a speed similar to laser (0.5 to 40 mm). However,  investment and production costs are much lower (ca. minus 30 %). Plasma can be recommended in particular for cutting hard metals and stainless steel.
Via plasma technology metals of 25 mm strength can be cutted. Elsign plasma machines can be combined in an intelligent way: High-performance milling motors do the engraving whereas plasma guns are cutting based on Hi-Focus-Technology.
