  • Plasma cutter

    Hi there.

    I am thinking about purchasing a plasma cutter for some aluminum parts that I currently get cut by water jet or laser.

    Does a plasma have as clean of an edge, if used properly with a jig, as water or laser?

    If it does it would enable me to save some money (never mind purchasing a new cool tool)

    The aluminum cut-outs that I require are 3/8" thick and 1/2" round. (like coins but quite a bit thicker). The second cutout is on 3/16" aluminum, weird shape, approx 2" x 5" rectangle.

    Is this something that a plasma can easliy do or is it best to continue on with the laser/water? A smooth finish is of utmost importance as sanding time is lost profit.

    Thanks for your input.

    On steel from what I've seen plasma will as smooth as well as the best properly adjusted o/a torch with a highly skilled hand. It leaves a slight grain barely visible if the machice is rated for a quality cut on that thickness. It's not as smooth as the water-cut pieces (don't know if the touched them up) I had but the water cut was never perfectly square either done by cnc water jet( always a couple or more degrees of tilt on the water cut pieces) PERSONAL EXPERIANCE hope it helps
