Dear friends ,
I have recently boght a chinesse CO2 laser cutting and egraving machine at 150 watts power
reci tube . But I have some problems when cutting metals .
I mention that I m using Oxigen for helping the cut .
But in my opinion the focus lens that I use isn ;t the right one .
The focus lens that came with the machine is a Zn Se type with 20mm diameter and focal lengh of 64.5 mm
Surfing the youtube I found lots of guys who cut 1-2 mm metal wiht 150 watts co2 laser , but i saw that the nozzle is
around 5 mm from the top of the cutting sheet area and in my case has to be 21.5 mm .
Maybe you can provide me some informations regarding my problem .
Best wishes ,
Costin .
