I'm not sold on the Ensis personally. The feed rates are too slow compared to the FLCAJ (which is what we have). If you're buying a fiber laser to cut thicker with oxygen then you're looking at the wrong kind of machine. Just my 2 cents.

We landed a huge aluminum job in our shop, the first real aluminum production we're going to run. This led to our discussion on how to prevent a thermite reaction when switching back to our typical HR P&O runners. The obvious answer is to clean the scrap trays and empty the dust collector. What...

Yes, we roll the carts over to the dumpster and shovel it out. The trays under the conveyor don't fill up as fast. Usually we pull them out partially and combine them into one tray and wheel it over the dumpster.

They should be on rollers. We just shovel them into a hopper.

Dust collector? We dump the bucket into a garbage bag and throw it away.

Not sure if it's an option as this point for you but we built a mezzanine above our laser and put all of the components on top.

You can hand load the machine.

I'm running an Amada 4kw Fiber laser. Duty is just the percentage of the power call out. Good luck.

Are you talking about etching? I typically etch using shop air as the assist gas. 500w, 350 inches per minute and about 20-25% duty. Works like a charm. You can use O2 if you don't have good dry air.

Networking is the best option for the laser. You can download all the programs right to the controller from your programming station. Bulk tank oxygen and nitrogen is the same. I've never gotten a Beam Overlap alarm on any of the newer Amada's I've ran since 2007.

4000W 250 IPM 1.5 bar N2 -0.02 Focus Edge quality is less of a concern than the burr.

I'm running a 4kw fiber laser and we just got an order for 11 ga aluminum. Our customer is making tanks and these parts are all exposed. Our initial test run of the material left dross that the owner wasn't happy with. Can anybody help me with some tricks for cutting a burr free aluminum? Thanks.

I'd probably turn the trace back on. Otherwise a clean housing, a centered beam and a proper Z-height should do the trick.

The Gen II Fiber laser engine from JDSU that Amada uses has 2 Fiber Laser Modules and a Combiner Module. This unit was what was in the crate. It requires a sterile environment to work on. Thus is why Amada issued the new unit. They are going to send the OG unit back to JDSU for testing. Here a...

Amada sent a new motor over on Friday. The plan is to replace the OG one. This is their Gen II fiber laser. Only a handful in the field and the first one to fail. Duane Lepianka is set to do the replacement tomorrow. There are only 1,500 beam on hours. I'll pick his brain tomorrow and see what I...
