There are many ways to cut mild steel plate, some of which are suited for automation some are not. Some are suited for thinner plate, some for thicker. Some are fast, some are slow.
There are a lot of things that can cause problems with plasma torch consumable life, and troubleshooting a problem can be complicated and time consuming. So we’ve put together a list of common things that you can look for if you are having problems, or if you just want to make sure you are getting the most from your CNC plasma system.
This is a question often asked by fabricators and steel service centers looking into the purchase of a new machine: should they buy a plasma cutting machine or an oxy-fuel burning machine? Another question frequently posed: should I cut this part with oxy-fuel or with plasma? Of course, this debate is limited only to those who only work with mild steel, since oxy-fuel won’t cut stainless or aluminum plate.
Although oxy-fuel cutting is generally viewed as a simple process, most machine operators realize that making it perform properly is not as simple as it looks. Experienced operators can achieve cut quality that rivals a machined surface, and do it in a fraction of the time cost of hard tooling. But consistently getting that quality requires understanding the factors that affect quality, and how they interact with each other.
In the previous blog on Flame Cutting we discussed cutting nozzle bore designs and the requirements for various plate thicknesses. In this issue we will discuss the different nozzle designs required for the various fuel gases.
