I'm working with a chinese laser cutting machine for 2 years.(JQ-1621 150W RECI glass tube, working size is 1600x2100mm) The only material we cut so far is acrylic (plexiglass). The material thickness varies from 2 to 20mm, although the thickest material I could cut at acceptable quality was 10mm. I want to buy a more powerful and maybe larger machine. US and European made machines are out of question due to their ridiculously high prices. US/European laser tubes are more expensive than whole chinese laser machines. I read the comments in this forum and people gave quite positive feedback about G.Weike. So that's one of my options. What other chinese laser manufacturers do you recommend? Please share your experiences here. (I'm gonna make the Import by myself -again- which should spare me a lot of money.)
