Laser welder Which one?


#1

Hi everyone! I my boss is finally convince that a laser welder will
be very beneficial to our shop. He is going to get one. But he wants
to know who to go with. We have just started researching, I am
starting here to hear any of your experiences with a particular
product good and/or bad. I am partial to Rofin, the german company
that pioneered the technology.

So what say ye?

Thanks
David

One of my neighbors in the Mart just did another laser welding job
for me, and I am posting a general recommendation for the Orchid
gang, since I am pleased with his work.

I’ve got, at home, an older Siro (like the B&D), and at work, a
Baasel lasertech, which is now Rofin. Between these two, the Baasel
is perhaps the better machine, at least in terms of sophistication of
the control systems. But I can’t speak about newer Siro/B&D models,
which I’m sure they have by now.

However, I recently also had the chance to work with CPP’s latest
model, and I gotta tell you, they did that machine RIGHT.
Beautifully made, with exceptionally easy access to all componants
for service, and a very well laid out operator interface. If I
were, without worrying about budget (which is why I bought a used,
five year old Siro) buying a new machine, I think the CPP would get
my nod. In addition, being made in the U.S. means that parts and
service are a good deal cheaper than if you have to import the parts
from Germany. Note too, that the engineers who designed the CPP
units were originally from Baasel lasertech… You’re still getting
german engineering, just a newer version, from guys who’ve moved to
this side of the ocean.

One other unit perhaps worth looking at is the line sold by Gold
Machinery. It’s italian, and from what I can see, offers a number of
interesting features. One, for example, is that the laser beam is
delivered to the glovebox by a fiber optic cable, as is used for the
surgical ones. This means that with their most recent model, the
glovebox can be a seperate, small, benchtop unit, while the power
supply and guts of the machine are out of sight and out of the way
under the workbench. And, they use a central fiber in the fiber
optic cable to take light from a visible red HE/NE laser to project a
red dot on the aiming point of the laser, instead of the eyepiece
crosshairs in the microscope. This may offer some advantages in some
situations, since sometimes, working in recesses, or complex shapes,
the work area can be somewhat shadowed, which can make the exact
aiming point of the crosshairs a little harder to see, while a
bright illuminated aiming dot would show up easily. I don’t know the
relative quality between these machines and others, but the guys at
Gold Machinery can certainly give you an idea.

Hi there, I do have a CPP LaserStar from Crafford LaserStar
Technologies, and I am very very happy with it. The company is
extremely competent, with a super costumer service. These guys make
their own machines, they know what they are talking about. Not just a
salesmen that sells you something and lets you sit with it! Take a
look at: http://www.crafford.com They are great. Klaus, A Jour Jewelry

Dear David, Please do not go in for a Laser Star 7000 Series
Workstation with EVS III Flat Screen System. We have had problems
right fm the start with the machine. Initially the Controller Card
had to be replaced and then the we had problems with the Flat Screen.
We were the first in India to buy the Flat Screen Workstation, we
bought it in the Basel show. However, we are not satisfied with the
product as we have not been able to use it consistently since May
2002.

In fact, we will now be changing fm this so called new technology
and will be downgrading to the older Binocular Microscope System.
Even for the conversion within the warranty period, Crafford is
charging us $2000. We certainly hope and pray that we will then be a
satisfied customer and recommend it to all of you at Orchid.

My suggestion is that do not go in for a Flat Screen Workstation.

Hope this helps you in deciding what not to buy!

Dilip Sheth.
