Which Chinese Laser

[Warren Eames]

Warren,

I recently purchased a LG960 from WKLaser, i've only just unpacked it yesterday and seeing as i head back out to sea tomorrow for a couple of months, will not be able to let you know how its going but for what it's worth here is what i've found so far.

The equipment arrived in two crates, one large one for the engraver, one smaller for the chiller, both were well crated with the only damage being to the mains plug on the chiller which had a pin bent over as it hadnt been tucked inside but was dangling down by the unit.

The laser unit itself was very well packed the crate being approx 100mm bigger across all dimensions which was then filled with packing foam and the machine was wrapped with bubble wrap.
I was actually very surprised when i uncrated it as the build finish was excellent, all the various doors hinged well, main access door on gas struts was very light, one problem is when they mounted the perspex inspection ports, the pex is slightly warped so there is an air gap between the pex and the door which will require sealing.

The drive electronics is housed in a well built enclosure within the machine with cable trunking installed for all interconnections, cabling is well run with service loops.
there is an opening on the underneath for the Data cable which would have been better on the side.
The Igus chain is well routed and secured

The chinese do seem however to get to the Earth cable and just wonder why they have a spare yellow/green cable in their hand? the mains earth was just floating around in the back and i've read this on a few other forums as well.

Mechanically all that i've inspected so far is tight, all paths have been slightly oiled, belts are all correctly tensioned and X/Y axis smooth
a good thing that impressed me is that all holes seem to have been deburred after drilling, a thing that often gets missed some times.
the internals are spotless, no signs of the Tuna sandwich someone earlier posted (i was starving at the time and i would have found it)

I ordered two tubes, these came in seperate boxes, the red dot pointer is mounted on one of these, both tubes are well packed and physically sound, the fact i'll be away for a couple of months means i'll void any warranty i get on the tubes (3 months). so i all i could do was physically inspect them.
The boxes were mounted inside the unit and were well secured.

The Rotary unit, blower, compressor, water pump were all boxed inside underneath the table.

One thing that does bug me is the cooling water inlet/outled bulkhead fittings are mounted right above the power supply!! mind you some of our offshore equipment has A/C units mounted directly above 3.3KV 500KVA transformers so its not just our Chinese friends that do this.

anyway, i know you were probably after more operational experience and i'm sure a few others will chime in with time but so far i'm pleased with what i've recieved and look forward to "crankin it up" also the fact that my one is WKlaser and not one of the ones in your original list, check their website and see if it looks familiar as there is a lot of rebranding going on.

Lastly, James, the fact that these are called threads is fitting, they dont tend to go straight rather they weave their way along.

Cheers,
Buschy

Thanks Buschy. Hope you have a safe time at sea.

I believe, however, it is a stretch to say *...eliminate those issues altogether...*.

Roy,

That's a fair statement.

"Mitigate those issues" would be more accurate, which I think you'd agree is a fair statement.

We bought both of the lasers before I found the engraving forums. Without the help of an outstanding service group and willingness to help me work through any problems I would have not been up and running for quite some time. Please don't write off the information available from the manufacturer, these people will be over enthusiastic about their machines but they are also the most knowledgable people about them. You will also find that end uses are as biased as they come, some like one brand and hate another even though the next person posting may feel the complete opposite.

Sandra,
You mentioned you have two Lasers. Could you let me know what the brands are and what is your opinion of them?

Warren when i purchased my laser from china i had them include some 19mm acrylic awards. Before next weekend i will test cutting one for you.
My machine is an 80watt. And most chinese sites say capacity for cutting acrylic for 80watt is 20 mm.
But cutting 6mm can be very slow. So i hope you got patience.

Has any one bought a 100W Chinese Laser Cutter? I am looking at the following manufacturers: Jinan Senfeng Technology, XYZ Tech, Guangzhou Yinghe Equipment, Rabbit, Sunnylaser. What success have you had? How long does the Co2 tube last? What is the quality of the engraving and cutting? I would be cutting 20 Acrylic as the biggest cut job. I am not interested in comments from the manufacturers themselves just end users.

Pat I look forward to your results. I am thinking I may have to go to a 120w machine.

the perspex inspection ports, the pex is slightly warped so there is an air gap between the pex and the door which will require sealing.

NOTE: An unlucky reflection could lead to instant blindness if the laser is open to air at any point...particularly if it's around the bit you're looking through. Please bear that in mind when you're doing the sealing.

[pat Lanigan]

Hi warren, i today cut 20mm through. I cut 5mm square in 72 seconds.!! As you know i have a 80 watt chinese laser. The cut piece is not straight. I will post you pic. There is a bow in the cut out length. Maybe more power is the answer.

[Warren Eames]

Pat at that rate the largest piece I would be cutting out would take about 1.5hrs it is 600mm long.
Has anyone else cut 20mm Acrylic with more than 80w power? If so could you please give me some time frame for a cut such as Pat has done?
I would like to get the right power on my first buy.

I am interested to purchase chinese laser

i would like to hear your opinion about this company

http://www.perfectlaser.net/

and their laser model :PEDK-7040

Thanks

[Dan Hintz]

Mladen,

That one is no different than any of the other Chinese lasers... they all steal from each other and use one of 2-3 different packages (all equally quirky).

[James Jaragosky]

Dan, what you call stealing they call sharing. All their high tech business is government subsidized so in essence all their business is interconnected. They take an” all of us against them” business approach, where we are all about the individual.

As far as their product quality is concerned, I can find more posts on this site of people asking for help with their American assembled machines than Chinese machines.
As someone who has owned and operated both the low end and higher end Chinese machines I speak from experience when I say that they can get the job done, And at 1/5 the cost of an American assembled machine I’ll put up with a little quirky

To answer the last posters question I have no experience with that company. I suggest you continue to do your research. Try not to take everything you hear bad about Chinese machines as fact. Most people commenting on the Chinese machines have never owned one let alone even seen one in person.
There is a lot of quality difference between the Chinese lower end machines and their industrial models.
In my opinion, the biggest problem with the Chinese machines is the software.
Good luck and best regards
Jim J.

thank you James for your opinion.

I work on ULS machine but I am intrested in chines laser
I have opportunity to see chinese laser on the work and they are very good in cuting and engraving on the wood but i did not see how they work with details engraving on the plastic and rubber.

I think between two company one is

and second company is

http://www.perfectlaser.net/

Your English is well enough for me to understand you. no apology is nessary.

You can get a rf laser tube in a rabbit laser as well.

I cut acrylic with mine without any problems. I have not tried rubber as of yet.
Your USL machine is a excellent machine. the Chinese machines are not as well refined as the American machines. However the chinese machines do very well for many people.

I can find more posts on this site of people asking for help with their American assembled machines than Chinese machines.

That's probably a lot more to do with volume of machine owners rather than quality of machine. You'd also find that 95% of those problems are solved the very next day. A point you don't see posted about the Chinese machines at all.

The point I was really trying to make is that many people bash Chinese machines without having any firsthand experience as an owner or an operator. They simple spread opinions that reinforce their view on something they have no firsthand experience with.
Also the put downs of the Chinese machines have no relevance to the posters question.

Like when a pc owner asks for help with a issue affecting his laser, and the first post is from a Mac user telling him” I don’t have that problem you should have bought a Mac”. This type of thing helps no one. It only servers to help the person doing the put down reinforce how well he feels about his equipment.

Are the American machines better built & supported? absolutely!
But that was not the question.

I just got a new 60-watt Chinese machine and I am quite happy with it. I had an issue with a bad flow sensor that was easily bypassed. I have been happily using the machine for over a week now without any mechanical problems. The software is new to me and I hate it. This will change, as I get better at using it.

For many people putting out 10 to 20 thousand dollars for an American machine is not a viable option.
If I had a business that depended on a functioning laser, I would either get a American machine or two Chinese machines. Two Chinese machines would be cheaper.

I have seen people who posted on the creek told not to bash a certain brand or company because it is not right, but is it ok to bash a whole series of products from a whole country made by many different manufactures?

I say, if you have firsthand experience with a product then speak up and let us know good or bad. If all you have is secondhand conjecture and opinion with no experience with that product then you should at least state that in your post so we can know from where you are basing your opinion.
Best Regards
