Laser cutting tiny parts
« on: November 26, 2021, 01:29:40 PM »
The precision of my fiber laser cutter never ceases to amaze me. These tiny parts are cut from 0.5mm stainless steel. The small holes are 0.6mm diameter.

I have a new fiber laser at work sitting in the crate on the receiving dock, we will un-crate it next week and move it into the shop the following week. It is a process because our shop is in the basement, we will also be removing a couple of machines that we no longer use. I'm looking forward to learning how it run it, and see what it can do.

I bet that this is material dependant along with Laser Power and type ....
As Stainless is a poor heat conductor, I expect a lot thicker than for instance Aluminium or Copper that are really good heat conductors, and quickly disperse with the 'Cutting Power' ....

That said - I'm curious and impressed too  :cheers:

It's a 1kW machine so can cut 10mm mild steel and 5mm stainless steel.

Is it an engraver? Most cutters would be too big to go into a basement. Mine has a 2500x1300mm cutting area.

No it is a cutter, 50" X 52" work area. 1.5KW which should be fine for anything we need to do.
We have a large freight elevator with 16k lbs capacity. The 3 Haas VM2 machining centers in the shop that all came down the elevator, lots of other lathes mills etc. Most of the sheet metal enclosure had to be removed on the machining centers, we ordered them that way. The old NC punch we are removing will be fun, it weighs 8K lbs, good thing for riggers.:Lol:

This is our new machine.

Looking forward to it, the punch that it is replacing is a 30+ year old cantankerous beast.

Dave, congrats! Very nice machine. Different league from my Chinese import. Mine is 3 years old now and has a Raycus source. Never let me down so far.

I did some experiments to see how small I could go. These name tags are cut from 1mm stainless. That's a pin in the foreground.

That's pretty impressive, are you using compressed air for cutting? have you tried any other gases, N2, 02?

Those tags were cut with N2. Since then I have bought a large compressor and use air instead. For carbon steel above 3mm I use O2.
