How To Achieve A Perfect Cut Condition On Carbon Steel, Stainless Steel, and Aluminum | Fiber Laser

[@meade916]

one thing I found to be a factor was when metal is thin and has even the slightest warp to it (or if you have damaged slats), the air pressure from the nozzle causes it to shake and shimmy up and down. I know the nozzle knows where the metal is but when the material is literally flapping like some of the sheets in this video did, it can affect the cut quality. I get around this by adding weight in strategic areas to keep the metal stiffer. Scrap steel or some of those little 1.5lb round weight-set weights work good.

Just what I was looking for. Great stuff!

Excellent video, thanks Dave!

[@willytrouble88]

Laguna Dave rocks! He knows his stuff. Great video!

[@darrelllejeune840]

I run a fiber laser table and could really use the parameters and piercing settings for .250 carbon steel.

[@sweetness8744]

Dave Thanks your videos are very informative, being very new to laser cutting it a great help the way you approach the outcome of the cut, make adjustments, thanks i be watching.

[@roadiesgarage3816]

I operate a 20kw laser, coming from a 4kw machine and the problems we all face still exist. But the extra power as long as everything else is on point, beam center is not as important as long as tolerance is not nats butt. Even when beam center is off it just blows through the nozzle and keeps on keeping on. Not cool but it is what is.

[@Пауль-п7х]

Thanks, great video. It's sad that my boss doesn't give me time to play with the settings like that. We got BM109 and BM111 with portals 1500x3000 mm.

[@jacobzimmerman1852]

Is this the 1.5 or 3kw machine?

Hi Laguna how are you and m from India but currently m doing job in Kuwait as a laser cutting operator and I want to come in USA so if you have any opportunity for me so please reply me

[@thiaggoacl]

Hi @Laguna Tools first of all congratulations for the video, excellent learning material. I would like to know what configuration on the panel is used for cutting .375 carbon steel?

[@LagunaTools]

Hi Thiago! Glad you're enjoying it. Oxygen and double nozzle are used to cut .375 carbon steel.

[@teddysponsler6220]

I want to learn more, because im looking to go into business myself and this would help. Question, why haven't they hooked this up to an robotics ?????

Ever have the cut head run into a chunk of top dross and drag the plate around?

[@meade916]

the machine will stop itself before it would do that.

[@abhitrivedi6861]

Sir why we use double nozzle in oxygen cutting,, please explain briefly

[@LagunaTools]

Almost all manufacturing standards recommend using a double nozzle while cutting with oxygen because it is an accelerant, and it is using a fraction of the assist gas when cutting.

[@deividerik7435]

With 3psi, contamination does not build up on the protective lens??

[@abhitrivedi6861]

How much kw of your laser, tell me reason why my all lenses of machine damaged,, what are the reason,,, I do cutting with sircompressor

[@LagunaTools]

Most likely this has to do with your air compressor. You blew up your optics because your air compressor is not clean dry air. It is of the upmost importance that your assist gas is as pure as it can be.

[@roadiesgarage3816]

The biggest complaints i recieved from customers was why can't I just install and go. Dosent matter the machine. Remember if your paying less for a machine there is going to be more know how necessary on your end.

[@gonf3273]

What is the best material to use for the spikes for CNC bed ...i have tried Steal, Brass etc. ,the tip gets damaged(because of laser) and causes unevenness in the cutting for high precision work. Any suggestion?? (PS. I use 2000W laser to cut Plywood, Acrylic etc.)

[@LagunaTools]

The Fiber laser has an optical sensing head that wouldn't matter the difference in the height of the laser slats. These lasers will not cut Acrylic, Wood etc. So the CO2 laser in question would either need a height sensor or replaced slats as needed.

My Laser Nozzel hit something, But I have no errors after reset, How Can i check the cutting head for damage ?

[@LagunaTools]

Hey there. If everything appears to look good and no alarms have gone off, try doing a beam alignment. You can follow this video here: kzbin.info/www/bejne/jaCcqoiXeN2NnpY

[@nickthedane1]

@@LagunaTools okay Thank you

[@abhitrivedi6861]

What's reason behind laser power source failure,, common reason

[@LagunaTools]

Usually there is not a power failure on the Fiber Laser. CO2 is a culmination of using maximum power and or maximum capacity of the wattage for a long period of time along with the negligence of proper maintenance and alignment of optics.

Hey Jeremy, the SmartShop® Laser | CBX has a laser power starting at 1KW and goes up to 3KW.

Piercing Suck.. The way you do for piercing will damage the protective lens so fast. however the cut look good.

[@roadiesgarage3816]

Service guy speaking. The big ugly truth is you can't control your material input conditions into the laser especially if non us. Foreign metals vary wildly in quality and personality during mfg processes.

[@bonifacemwaura6993]

Good cuts. But the piercings for me are not Good.

[@LagunaTools]

Hey Boniface, This video shows both correct and incorrect forms of piercing to educate how to adjust specs to reach an optimal pierce. Dave verbally covers that on some cuts that aren't up to standard. Thanks!

[@zacsdiyguns]

Customer service is not good

[@johnhutchinson605]

It's funny watching the pierce parameters on this video. The lead in is way too slow. If the settings are set correctly you should not be getting those massive globs of molten metal on top. Those globs will cause the laser head to lift up when the ohmic sensor dedects them and will have a huge imact on cut quality at the lead in or lead out. For 3/16" the lead in should be around 1 second tops.

[@LagunaTools]

Hey John, Sorry for the confusion. Throughout the video Dave is giving both good and bad examples of cuts. He advises adjusting your specs when cuts aren't clean, most of the time being your gas pressure. At 4:43 he shows a metal piece that wasn't cut correctly and recommended adjustment, this is one of the passes where some metal globs were created but were addressed. You are correct though! The cut condition is only going to be as good as the piercing, and it's important the operator knows how to adjust it when needed.

[@johnhutchinson605]

@@LagunaTools I was speaking more about the actual pierce section around 3:36. This pierce timing and power is clearly well off. You can tell because the head begins to descend to the material before it's made a full pierce hence why at 3:33 you will see what appears to be a volcano of sparks flying up. This is a result of not making a full pierce, and then pausing which pre heats the metal and then it begins doing its slow descent and lead in and starts shooting slag everywhere. It is an issue because that can cause backsplash relatively prematurely which will contaminate your secondary lens and require replacing... Fortunately they are relatively cheap $5 or so a piece, but it's avoidable. This issue that I was talking about initially becomes very apparent at around 4:07 where the ohmic sensor causes the head to start bouncing up and down.

[@johnhutchinson605]

Also, stating that striations are 100% attributed to gas pressure is kind of misleading. Striations like this are a function of primarily too little power or too fast of a travel rate. The gas pressure is important yes but it's really only there to help heat up the cutting point and assist in sublimating the material. Too much will cause the backside to fuse back on it self and cause dross yes but running the settings under powered or having the travel speed too fast would be a bigger contributing factor (hence why the striations appear angled like the bottom of the cut path cant keep up with the leading side or top of the cut path). Also... it's not recommended to cut hotrolled steel with the Raycus laser source... IPG maybe but cutting a lot of hot roll with a Raycus head is not recommended by the manufacturers of these machines. Not sure if he talked about it but almost more important than any of this when setting up the paramaters is to ensure you pick the right nozzle. For1/4" you want to use around a 1.2" or 1.5" nozzle.
