I am after a bit of advise on whether to buy a cnc plasma or a flame profiler. I will be primarily cutting 10mm, 15mm and 20mm plate some hardox. Anyone own either cutting machines and could offer some advise? that would be great.

Thanks in advance

Plasma. More versatile than the gas. 100+ amps and you'll be good to go up to about 25mm mild steel.

Thanks for that do you know of any decent cnc tables? The cheapo ones on eBay look ok but not sure on accuracy for bolt holes etc.

Mines a SwiftCut. Tis about 7 years old now and not been a lot of bother really. A few niggly things to begin with which were sorted under warranty but it generally behaves itself as long as its maintained.

I have seen a few swiftcut for sale locally one has a 200amp plasma with it. Does hardox cut ok and not chewy? Bolt holes not to tapered?

I've never cut Hardox with mine so can't comment on that. I think the general rule with holes is that the diameter needs to be at least twice as big as the metal is thick to get something like a decent hole. I have been known to plasma the hole to get the position and then run a punch through it to true it up.
