Hello all, I work for a small 10 man fabrication shop and do all of the cutting on our plasma table but am having trouble with bolt holes. Particularly in thicker plate. I know taper is common with the plasma process but I am trying to see if there are any tricks that I am missing. We have a torchmate 4800 with the Flexcut 80. I am not super well versed with the different options on the market but I am sure there are some better and worse. We cut a lot of 1/2" plate which is where the taper problem is most apparent. I ran a test with .500 holes with brand new consumables and got two holes that would fit a 1/2 bolt before developing a the taper that prevents the bolt to fit. I am running the feed rate about 60 percent of that of the outside line and using an over burn of .100-.250. I also adjusted kerf settings to match those seen in a line speed test. Any recommendations would be greatly appreciated.
