Hi, I cut gold, silver and brass almost every day with my lasers, with a 30w I cut 1.4mm of gold, with the fastest 50w cut and I also cut aluminum from 1.5mm and steel up to 1.6mm. Some materials are difficult to cut, like silver, but they cut well with the right parameters
Hi Greto. I have 50W Fiber Laser, and i would like to ask you,what are the settings you use for silver cutting ? I mean speed power, and wobble. Thank you
I know this may be redundant but try the going the other way with speed.....faster and no wobble. With no wobble I will sometimes have to de focus about 1mm half way through the cut. I use a 50watt and this has worked well for me 1500-2000 at 80-85% power.
Massive respect to Benchworks for reaching out with the loan of gold sheets for testing.. That was extremely cool of them. Also thank you Alex for taking the time to do the work and share the results. Remarkable work you do and talent you have. I would be curious to know just how much gold was lost due to the cutting process.. Perhaps Benchworks could share the info after they remelt and weigh the gold and you could share the info on an upcoming episode.. Thanks again bro, extremely interesting video.
I am struggling with cutting .83 silver now ( 22 ga) using Corel I actually made a .2 mm thick line so that I could ablate a larger swath then a single line would offer. I will try the wobble feature on ezcad2 to see if that works better. As far as the heart piece you are working on you can ablate the oxidation just by doing a quick pass rectangle over the entire piece @ 40% power for a 50 watt laser
Thanks for the tips, we ended up doing something similar in the follow up video "Gold Cutting Secrets" so check that one out if you're still struggling with the silver because we do make a fair amount of progress in that episode.
@@LaserEverything From watching videos it appears that a 100 watt laser is much faster than a 50 watt laser. It would seem like the relation should be linear but in reality it seems like a 100 watt is 5 times faster. I might just get a new laser source
Thank you for giving it your best. I know that I would be very intimidated in attempting such a feat, not only because of the materials reflectance but the cost of the material.
The rubber jaws seem like they would be thermally insulating the gold as opposed to a big heavy block of machined aluminum like that Mactron one you show at the beginning. So maybe to counteract the warping put a big chunk of sacrificial aluminum behind it as a heatsink?
In lightburn with a 60W MOPA and a 110 lens my settings are: SPEED 60, MAX POWER 85, FREQ 37 Khz, Q PULSE 200, Num Passes, 75, Perferation mode on, 0.05 CUT, Skip 0.01, Wobble Mode on, 0.0330 STEP, 0.0300 SIZE, Kerf Offset 0.050 OUTWARD. This worked well on .5mm thick 18K Yellow
Thank you for sharing! We saw your other post as well. If you haven't would, be something cool to add to the Community Fiber Laser Settings Library we added to our website in the last few weeks. lasereverything.net/ It's at the top under Settings if you're up for posting it.
Do you have a logical analysis, based on it, that leaves no room for doubt? Regarding irrecoverable waste, as a result of burning and oxidation. Regarding gold dust that can be collected, we have the solutions for that.
Excellent video. I have already cut 1.25mm thick 18k gold with the machine I have. I wish you could make a video using rotary Mark. I would like to engrave vectors inside a ring but I don't understand how SplitMark 2 and rotarymark works. I only engrave text with rotarytextmark
@@MscassieClancy I have a Fiber Laser Dowin 50w. Activate wobble and set 0.1 diameter and 0.01 distance the parameters would be 300 speed, 90 power and 30 frequency. On my machine I only need about 20 passes to cut a heart like in the video. I recommend you to pay attention to the loss it generates when cutting, usually 0.3-0.4 grams. I'm going to try it with Alex's parameters to see if it generates less material waste
Copy that, I'll see if I can get on this in the near future. In our rotary setup video on the channel we cover the basics of RotaryMark so you may want to check that out in the meantime.
I cut my gold pieces with 30w without problems. I think your wobble diameter is way too small. I use 0.1mm and distance 0.05mm Power is 80% speed 25 and freq is 25. 0,7mm thick 14k yellow gold takes just 7 passes and you can pop it out without any tools. I am using fine sanding paper or emery sponge to clean it. I like the finish from sandpaper, but you can polish it without any problems :)
I’m a jeweller just bought this 70 watts raycus , to cut gold and silver names, and I don’t know if it will do the job . I have tried already on silver and brass, and I’m not satisfied . On gold I didn’t try it yet , I’m preparing some plates different thicknesses to test it . Let you know when I’m done .
@@desroseaux1 Je suis de l'allemagne et on a une bijouterie à Dusseldorf ou l'ont fait de la gravure et du découpage sur l'or et autre y compris plating sur le Silver
So im just learning how to engrave with a fiber laser but i believe you can do it with an automatic focus laser system the riser lowers half a mm or so as it cuts. Could this be your problem? Have you tried to do so many passes then lower the laser to focus to cut as deeper. So its the same depth taken away as the first loop of passes and repeat process until its through?
My suggestion is to mark it with laser and cut it with jewellers saw. The saw can follow the marked outline. The cut is fine. Even with a saw edges will have to be finished. One consideration is annealing the gold, makes it soft. It has to be forged to harden it back up. It has to be hard to wear well. Did you try annealing the gold to create excuses on the surface. That might cut down on reflection. Try marking after annealing. It will need to be pickled and polished anyway. I have not thought about the science behind how the laser affects the gold. I don't know how the vibration of the beam, changes the metalurgy. You certainty have given a hobby jeweler a lot to think about.
lol these are all great suggestions. Some of them are a bit over my head as I'm not a jeweler so I don't have a lot of the tools and techniques down that you do. Every single operation we perform at my shop is done entirely with laser but if I ever want to get into jewelry a little harder I will take these suggestions to heart because they definitely seem reasonable.
We address some of our shortcomings from this video, including wobble, with a follow up we did. Here's the link: ua-cam.com/video/FHOZWlvnu4w/v-deo.html
The laser you used is 30 watts , right? I will try with my 70 watts soon , on a gold plate 0.50 mm and 0.80 mm I’ll let you how it goes . If I don’t mistake your plate was thicker than 1 mm The finish you had on the heart , is not what I’m expecting to have with my 70 watts .
I think your speed and wobble settings are wayyyy off! Firstly speed - at slower speeds, you tend to get remelting of any crap formed from the cut, while running at higher speeds prevents this. If your spot size is say 0.04mm and you want 50% overlap at 37kHz, that's a speed of about 700mm/s. Second, wobble. As you cut through material, the edges will taper - this seems to be an inherent feature of the cutting process and doesn't depend on lens focal length. If your wobble isn't wide enough at the top of the material, the by the time it makes its way to the bottom surface, the two edges of the cut will have met in the middle and you won't make it through. Thicker material = wider wobble. Not sure how the settings would be for gold, but I cut a lot of silver, and for 1mm silver I use a 0.5x0.03 wobble. Again, don't space the wobbles too close or you'll remelt material. 0.03 spacing seems good for everything. So I'd try 500mm/s 90% 37kHz with that wobble and see how it goes!

Hello Viswas Soni! I have not mastered cutting gold yet but I am trying to do it better. One suggestion I have heard is to make the wobble much bigger. Try a diameter of .33 and a distance of .01 and see if that helps you! This is what I have heard to help.
