Laser Tree 20w

[Percival Blanco]

Airassist helps in two ways, prevents scorch marks around your cuts (discoloration) and also pushing the fine dust out of the way so the full power of the laser makes it to your workpiece. When cutting, it makes a tremendous difference in the penetration you get and how clean of a cut you will get. For engraving with a lower power, it helps give you really crisp sharp lines. But on top of both of these things, just having air assist on slightly will keep positive air flow at the laser preventing build up on your lens (which is a typical way of causing laser failure).

LASER TREE 20W Optical Power Laser Module for Laser Engraver Cutter, 80W Laser Engraver Module with Air Assistance, High Accuracy Quad-Compression Spot Laser Head, Engraving 340+ Colors On Metal Steel

Precision Carving at its Finest: With state-of-the-art technology and an ultrafine laser spot size of 0.03*0.03mm, Longer Ruby can achieve intricate details down to the millimeter, crafting perfect engravings on metals, plastics, and beyond....

I had high hopes for the NEJE A40640 laser, but aside from rudimentary resting, never did much with it on the LR3, mostly due to never being satisfied with the air assist function, and by the time I got to more advanced testing, I had replaced it with the NEJE E40. Both are 10W optical output lasers, so basically twice what the Genmitsu could put out. I was pretty convinced that I really wanted/needed air assist for them, given the disappointing cutting performance of the Genmitsu.

LASER TREE K40 is a true 40W+ output laser engraving and cutting module designed for powerful cutting. It uses beam compression technology to combine 8*5.5W laser diodes into a single powerful laser beam with 40W+ laser power.

Its power can give you a completely different cutting experience. In order to improve the compatibility with different laser engraver machines, K40 provides a solution by an adapter board for electric compatibility and a sliding plate with multi holes for installation compatibility. Electric compatibility can be checked easily by 'power' and 'signal' LED indicators.

K30 laser module is compatible with TTL/PWM-controlled DIY machine, laser engraver cutter machine, CNC laser machine, and 3D printer machines. The adapter board is used for compatibility (suitable for Z*aitu,O*tur,Tw* Trees,S*ulpful9, Xt*ol, A*omstack and other models of DIY laser engraving machines). The sliding plate has multiple holes for installation compatibility.

For orders we will ship on the principle of proximity, products shipped from overseas warehouses will arrive faster (1-5 days).

If the item you ordered is temporarily out of stock in the overseas warehouse, we will arrange free expedited shipping. Delivery can be made in 5-8 days under normal customs clearance.

The LT-4LDS-V2 is a professional cutting module designed for long-term safe cutting and fine engraving processes. It is a blue laser head with an output of 20W optical power. Compared with V1, V2 has been greatly improved with a new housing design, easier to use air assist, longer focal length and more stable cutting output power. Cut 10mm of plywood at 3mm/sec at a time, easily creating the desired effect on the pattern. If you spend most of your work time cutting, then the LT-4LDS-V2 will be a good partner for you.

The new laser filter has a single-sided viewable window design. It not only prevents blue light from stinging your eyes, but also allows you and people around you to watch laser engraving without goggles in the reserved window.

To me, after watching some trees being taken down last year on our property, controlled felling. They brought in a mini-crane, strapped cables around a section of tree/limbs, sawed them off, directly loaded onto a trailer or into the chipper, on to the next section. No fear of damaging anything around. Still need men and heavy equipment so go for the controlled demo.

had some blighted oak trees removed a few year back. They could not get cranes or lift trucks in. They climbed, roped off sections of tree, and chainsawed them off while being strapped onto the tree. Very risky occupation, I only watched for about 15 minutes and my stomach was doing internal jumping jacks, lol. All went well, no property damage, no injuries. That is a young persons occupation, lol, but pretty lucrative. I did not begrudge a penny of what I paid them, they earned that money !

I talked to the owner of the company (he was running a crew), asked him about finding people to work, like just about everyone else, he could hire twice as many as he has but no one wants to do it. He had a 3 month waiting list for non-emergency services.

There was a story on the local news in Portland this winter after the ice storm. A 150 ft tall Douglas fir tree that was leaning towards a home needed to be removed. A Private Equity-funded tree service told the homeowners it would cost $30,000 if they could do it with a large crane or $100,000 if they needed to bring in a helicopter.

Yes. How is this not a weapon? If it can cut through wood it can certainly slice through flesh even more easily. Powering it with a generator has to be easier than carrying a truckload of shells up to an artillery position. And if you can aim it with such precision that surely you can cut through telecommunication lines and other parts of infrastructure so as to dislocate and confuse the enemy.

It's not antiquated until somebody comes up with a better

method, and actually puts it to use (goes way beyond the

"idea" stage).As James pointed out, this would be a fire hazard.Markp.s. I used to work for a laser company and the sales people

had some great stories. One day they got a call from a rancher

in Australia, who had a problem with wild dingoes jumping over

his fence and getting to his livestock. He wondered if a laser

could be set up to decapitate the dingoes when they would

jump the fence -- but of course, NOT harm people, or anything

else. The "Dingo Decapitater" became a running joke among us.

The applications that used to come in our front door always seemed

to top the previous ones. We did a whole lot of medical stent cutting,

balloons for stent inflation, etc. One of the worst one's that I had to

do the R+D on was seperating the vein from the artery of human

umbilical cords. They brought us bottles of human umbilical cords,

and we'd thread glass rods into them to straighten them out, then

try running them under the excimer's in different configurations to

see which left the least amount of charring, etc. Def. one of the

grossest things I've done, stunk like heck, and the things were like

giant gooey spaghettii noodles. I think at least every single guy in

that shop had to run and heave at least once, if not from handling

them, but from the smell. But that process is worth a small fortune

to be able to "recycle" the artery for heart surgery, I think they get

about $500 USD an inch for the artery's.. And we did do "retrievals"

of used stents offsite at two of our clients who had their own morgues

and autopsy suites. Yeeech..Doug (gotta go gag..)

I think this laser tree surgeon idea fits what we used to refer to as the

"James Bond Syndrome" from Goldfinger. After that film, everyone thought a

laser had an infinite depth of field and could cut through metal like a hot

knife through butter. In the real world, lasers require a lens to focus the

power to achieve the power density necessary to even scorch a tree; to cut a

limb 10-20 feet away is quite impossible. It seems amazing that people do

not understand even the basic laws of physics, optics, etc. - Russ

Can't say I'd know where to look, but I did hear about something along that

line. Also, I believe that the lumber industry in B.C. Canada got into

something like that at one time. They also had, or may have some type

of laser/lightning re-direction system. A lot of this was supposed to have

come from a mysterious "Dr. Nam", a Korean researcher who developed

some very high power, but incredibly simple Co2 amplifiers back in the

mid-80's when I first lived here. He was supposed to have built six osc's

each one capable of generating 10Kw and this was supposedly done in

a wharehouse in Vancouver. Back then, and possibly now, the Vancouver

stock exhange had the reputation of being the exchange of the mob and

other various tax fraud schemers, etc. And they had this R+D tax credit

scheme going here that suddenly found lawyers becoming "scientists"

overnight in order to take their chunk of tax credits and turn them into

cash. The one gotcha is that they had to find willing "dupes" that would

actually do a little r+d to make it look legit, and this Dr. Nam was one

of the more famous ones. When that project went bust, I heard that the

laser amps were busted up and given away to various CDN research

co's, govt. agencies, etc. There was supposed to be one used to try

and do the lightening attraction/guided path type stuff. Another was

supposed to have been put on an ice breaker to be used for trying to

bust up ice up in the poles, and then one went onto a flatbed rail

car to be used to weld rail tracks..

But this is all urban legend as far as I know, I'd like to hear

from anyone that knows about any of this stuff, or the "Dr. Nam"..Doug
