Amada used to have a handout in PDF called the "Cutting Know-How" which included pictures of Steel, Stainless and Aluminum Cut which was pretty good info. I would contact the Applications Department and see if you can get a copy of it.
As far as not having the nozzles, I would take a 1.4 Eco...
The mode will make a world of difference when cutting steel with oxygen, as well as a constant flow of oxygen. Based on the information you provided, you're cutting 1/4 and 3/8 just fine. In my experience cutting with this machine 1/2 was tricky at times but was mainly material related.
To...
This one never made it to the States or anywhere else for that matter for the same reason, spares. I would put a call into Amada Japan.
Sorry I can't be of help on this one.
I would certainly spend the money for an ECO Head since this is mostly used for what you described, high speed piercing on thick plate up to 0.5" (12.5 mm). The WACS Head is nice to have small features on thick plate (0.5" to 1.0") like a 0.375" hole in 0.75". It is a bit cumbersome to use...
This machine should be able to cut 6 mm Stainless NO PROBLEM. Where are you putting your focus point in relation to the material? What is your gas pressure, feedrate, power? What lens are you using? What is the condition of the lens? Have you checked for stress fracture on the lens itself? Are...
I think you may want to play with your modulation which at 30% may be OK but I would certainly play with your laser basic power. I agree with Henry Rollins as well in double-checking your braking and acceleration factors and to also call the apps. department at Bystronic.
Adekker,
Here is what I would use for Pulse Cutting this hole:
Power: 1800
Freq: 10
Pulse Width: 25000
Gas Pressure: 0.8 bar
Feedrate: 150 mm
You may be able to cut this hole using CW but you more than likely have to play with the power and feedrate and maybe modulation.
Hope this helps.
I agree with maayhemm's recommendations with the only variable being the focus point in relation to the material. In thick aluminum cutting (specially anything thicker than 0.25") you want to have a shallow focus point in order to not only cut but pierce easier as well. The dross on the...
Pierce Nozzle Gap seems fine, just curious to find out what material thickness are you cutting that you need a nozzle gap of 0.012". I've only seen this on thick stainless (0.187" to 0.75").
If you are cutting gauge material (22 GA to 10 GA or 0.030" to 0.135") I would use a nozzle gap of...
Nozzles usually wear out faster when cutting with Nitrogen at high pressure due to the fact that they sit closer to the material surface. That being said, what is your pierce nozzle height for piercing/cutting?
As far as build up, is the Stainless you're processing PVC Coated (Plastic Vinyl...
MikeMech,
The issue is with the table is weight, the inertia factor can cause damage to the ballscrews. Yes, you should be able to cut up to 3/4", the Fanuc resonator loves thick plate. Heck, you can cut 1/2" HRS with 1500 Watts. This machine has been around since the early 90's and was...
I think both manufacturers make a very good product and both have advantages and disadvantages as well.
The Amada has Fanuc Control, Drives and Resonator which is RF Excited with more power than the Mazak's Panasonic DC Excited which would require a bit more maintenance in the long run and...
I haven't cut Titanium on a Trumpf Laser but I have on Mazaks (1000/1500 Watts), Amadas (2000-4000 Watts), and Bystronic (4400 Watts) as thin as 0.020 to 0.500". You will need 100% Argon on the thicker stuff, you can cut the thinner with Nitrogen but there will be too much oxidation from it...
Just like krugtech and laserninja told you, babysit the machine and don't walk away from cutting. Laserninja is right about using oxygen for cutting copper even if it's thin. I have cut up to 0.125" with oxygen on a 4.0 Kw Amada Gemini. Hairy at one point but I did it.
How bad is copper...
By the way, which machine do you have? Are the lenses you are using plano/convex? meniscus?
Are the lenses you talk about 5" FL or 7.5"? If you are using 5.0" FL on thin material, are you going shutterless or pierce on the fly? What are you cutting that is causing a lot of spatter on the...
II-VI is the Cadillac of the Industry as far as optics and they suppy almost all the OEMs (Amada, Trumpf, Bysronic, etc).
You mentioned on your post that you checked the lens for stress. Did you check this with a couple of polarizing lenses? Can you also define the lens getting dirty?
I...
I was able to find some info from my old files. Hopefully this will help.http://files.engineering.com/getfile.aspx?folder=278a6845-edb1-4f35-8498-b1cd4d520a66&file=Lens_Savers.pdf
My sugestion would be to spray some sort of welding anti-spatter agent on them before you start cutting. The problem is that titanium sparks cool so quickly and adhere to other metals.
This may sound kind of ackward but long ago when I worked at the jobshop level we used to coat the back of...
Why don't you make a program that pre-burns the lead-in only? The bubble effect only happens during the piercing process and not during the cutting
To add to what Laserninja said, if you are using high tack PVC (AKA laser-film) you don't have to use this pierce macro at all.
