I have had my homemade CNC Plasma up and running now for well over a year, and it has really earned its keep
Yesterday I got a job to cut a fireplace Plate out for someone.
It consisted of a 800mm x 250mm plate with 3 rectangle cutouts, and 3 round holes.
The material was 1.5mm Galvanised steel sheet supplied by the customer.
I was a little worried beforehand about how the plasma would cut the material, But it cut it absolutely superb!
There are absolutely no dross or even a burr and it looked like it had been cut on a Laser!
When I cut mild steel normally, it cuts OK but there is sometimes (usually) an easily removed dross that I have to remove.
Why did the Galvanised material cut so nicely?
I would love to get it to cut normal mild steel as nicely, I am really puzzled......
