Re: Trumpf Trumatic L 2503 Floor plan & Foundation Instrctions

Your machine sounds close to one of the ones that we are running except for
the power. Knowing the turbine history is critical. They are really
expensive and time consuming to replace. We just had ours replaced by the
Trumpf techs. Minimum 3 days down time. They usually something else goes
which has become the weak link in the system. On the up side, when they do
work, they are workhorses.

As for the foundation, Trumph in Connecticut or Germany should be able to
provide you with the information that you require. If that fails, I might be
able to dig up what we did in my paperwork. Unfortunately, I won't be back
to work till in the new year. Post a message if you can't get information
and I'll see what I can do for you then.

HI Everyone . Greetings and best wishes for the Holiday Season.

We bought a Used CNC laser cutting machine make TRUMPF, TRUMATIC L
2503 LASERCUT, X/Y = 2540/1510 mm,with TLF 1200 turbo, capacity 1200
W, with BOSCH-control TRUMAGRAPH


well, first of all, check the number of hours on the turbine.

the most common reason for selling the TLF series is because the turbo is
out of hours. They are NOT cheap for a turbine rework either, USD 20K.
But, that is a LOT cheaper than the rework if the turbine fails ... before
you buy it get the turbine maintenance record and check it. phone the
company that did the rework (Usually Trumpf in Germany) and make sure the
hours are genuine. The 2503 is quite old now and there are a lot of them
about that have expired turbines ...

Second common reason for selling is twisted resonator. just dont go
there. Be sure to see the machine running and get a competent laser
service guy to burn a mode pattern from the laser. If you cant get a
decent mode, forget it. walk away. You can re-aling the cavities, but few
people outside trumpf have the skills. A cavity alignment and service is
about 30K

So, assuming you dont have either of those problems, then it might be
worth digging the foundation. Your installation guy should know the ideal
foundation anyway. You cannot just assemble these lasers and fire them up.
the alignment after moving them and isntallation normally takes a
trained guy with an assitant around a week. The fold mirrors never seem to
line up the same after a move. Don;t try and install it without someone
who has installed a TLF series before

The commisioning of these things is not easy, so, don't try and do it
yourself, the chances of you bringing a TLF series up from cold, with no
prior knowledge are not very high. You really need to use a Trumpf trained
guy in my opinion if you don't want expensive mistakes! Fast flow axial
lasers do not like being moved.
