CNC oxy fuel cutting prices
Installed an oxyfuel torch on our 5 x 10 Dynatorch table about 5 years ago. The oxyfuel feature is easy to switch over from plasma, very user friendly, only taking a few minutes to switch back and forth. Even so it only gets occasional use in oxyfuel mode. The question I have is this, what is a fair way to price out cutting charges when using oxyfuel which with the price of gas nowadays is not cheap. What would be a fair price on one inch plate and up? I was cutting 1.25 plate tonight at 10 inches a minute, worked well. Thanks for your input!!!

Re: CNC oxy fuel cutting prices
We run oxy/acetylene on one of our CNC tables. We don't preform outside work however we did cost analysis last year.
On oxy/natural gas there was some cost savings on the fuel gas ,little longer preheat time, on thick plate we have to watch as natural can roll the edge of the kerf a little if parameters are off a little.
We primarily run Acetylene and as you know the cubic foot price of that has gone through the roof. We use liquid oxygen, save some dollars there.
We have used Mapp, Hydroflame and a few others over the years but always came back to Acetylene.
That said just handing full size heavy plate and getting squared up on the table takes twice as long as say 1/4 plate.
Lifting off the cut parts depending on there size can be an over head crane deal as well as lifting off the plate skeleton.
So for heavy plate cutting we never figured by the foot but by the hour. I know some will disagree and that's o.k, this system just worked good for us. You have to figure the steel, your machine, labor, gases, overhead and the bigger the company the more it costs, workmen's comp and all that stuff a one man shop can avoid.
Even if your not cutting full sheets don't sell your self short, at the end of the day its got to be profitable.
Figure ALL your costs and time used add a reasonable profit and divide by the inch of cut if that works for you
Hope this helps.
