Hi everyone, To pierce stainless steel from 8 mm upwards, I use the M103 A3 function (with pre-hole of 1 or 1.5 mm in diameter).
The machine performs a first piercing phase using line 103 (power 3000, hz 100, duty 25, oxygen assistance gas and 6mm nozzle height). in the second phase he performs...

hi, i know that fiber lasers have protective covers for the lens, unlike our co2, but since you have found contamination (splatter or dot) of the protection on the outside (if inside it was very serious), there are various causes that I can hypothesize since the only thing you said is that you...
hi, i try to help you even if we have an old amada beta3 co2. that material I cut with a 7.5 "lens, oxygen as cutting and piercing gas. the nozzle height during or piercing must be greater than 1.5mm (i use at about 3.5- 4.5mm) gas pressure not very high between 0.6 and 1 bar. You must be sure...
hi, but amada lc 3015 what? 4kw? on an old beta III 3kw i use :
7.5" lens
1.4 double nozzle
gas oxigen
speed 1450 mm/min
pwr 3kw
hz 1500-to 1700
duty 75
pres 0.05mpa (0.5bar)
time gas 0.7

focus +2/+3
we dont cut a lot of this thickness but in six year i never touch this parameter...
no no the material is 10mm, that is due to the fact that we have the sheet metal warehouse and the various pallets have different heights of the gratings (fakir beds), this is because we have to reduce the contamination of the stainless steel from the splashes of molten material coming from the...
in my machine settings, the focal zero of the 7.5 "lens (" focal [mm] "in the cutting conditions) is the number 8.1mm.
with this phrase -in my machine settings ...- I mean, that in another screen (which I have not posted the photo now) there are the basic settings / parameters of the 2 lenses.
E1 very small holes
E2 for hole < 10mm of diameter
E4 > 10mm diameter
E6 outside cut
E10 marking
i use pirc. condition 101
my zero focal position (minimun diameter of laser beam on the surface of a thin sheet) for both lens is approximately 12.5 of the B axis.
in my machine settings, the focal...
hi, what are your cut parameter? i cut with an old amada 3kw beta3 10mm with oxigen.
speed ( slow but safe speed) 1200mm/min
power= 3kw
frq=1500hz
duty=68
pres=0.6 bar
nozzle gap 1.5 mm
focal point 2 to 4 mm above the surface (now i dont remenber)
i use the 1.4 double nozzle
lens 7.5"

we have an amada 3kw c02.I use to make dark markings (oxygen).
speed (7000-5000 mm / min)
power 1000w;
hz = 1000-1300
duty = 18 with 1000hz and 23 with 1300,
low pressure 1.0-1.5bar oxygen.
nozzle height between 1.5 and 2.4mm.
with this configuration the writing remains visible even after a...
Thanks for the reply. I'm pretty sure that the focal length is moving in the right way (the machine works well). I want to clarify, these are the first tests that I carry out by cutting steel with air. however I will try the focal again to be sure. I still try to play with the focal length but...
I try also 6 and 8 but i cant remove the burr.
The pics and the parametri are of the 6mm

this is 2mm mild steel( but i had the same result with the 1.5mm), i try to cut with air at 5bar with 2mm nozzle but i cant remove the burr. i tried to go up and down with the focal but nothing happened.
i try speed from 3500 to 5800 and duty from 60 to 100 . Can anyone help me?
what kind of laser does it have? does the machinery work well before? "follow start height" what value does it have? and the "z retract"?
usually, you can move the b axis without activating m100 (Opens the mechanical shutter and enables laser operations).
M104 (Cancels M103 mode, turns laser...
1=double nozzle (1 or 1.2 , 1.5 mm diameter for low pressure oxigen and 3 or 4 mm for high nitrogen cut)
2=nozzle for oxigen ( from 1 to 1.25)
3=conic (diameter from 1 to 4mm) i use 2mm diam. from 0.8 to 3mm SS(stainless steel) but in your case if the thickness of the material exceeds 3mm, try...
TMlaser Before starting to test, make sure that the setup of the machine is ok. lens in good condition, good seals (of the lens and the head), no deformed nozzle, and centered as it should be. this to avoid not getting lost on the way to cut well. yes, with the 7.5 lens you can cut everything...
hi, we have an amada beta III, it is not a runner but it does its job.
we often work with "architects" (people who should go to harvest the grain) and almost always give us horrible drawings to cut.
check in the drawing there are drawing are double lines, micro arcs or lines (once we found an...
thank you very much. hmmm. very interesting ... it looks the same as cutting with nitrogen but with less pressure and with the focal length at +1 (in the clean cut I am at about -1).moreover, for sheets under 4mm I use a nozzle gap between 0.4 and 0.5 to be sure to eliminate the risk of contact...
