500W IPG fiber laser cutting of 4mm SS with oxygen

500W IPG fiber laser cutting of 4mm SS with oxygen

500W IPG fiber laser cutting of 4mm SS with oxygen

(OP)

Hi..

I am new user of 500W IPG fiber laser, I am facing problem of lots of dross at bottom side while cutting 4mm SS304 with oxygen.

I am using pre-set cutting data but its not helping much.. using speed 1m/min, power 500watt, freq. 20,000Hz, using 5" lens, 2mm nozzle and gas pressure 4bar. During cutting...melted parts stick to bottom surface and its very hard to remove it. when I asked to machine supplier they said that SS cutting with oxygen has this default characteristic!

Some of our competitor having similar power laser machine and they are having clean cut! its really disappointing to loose business because of bad cutting quality.

If existing user can help me out?? welcome for your comments!!
