I just bought a commercial Plasma table cutter in need of a new control. its an old Cybermation unit http://www.cimtec-inc.com/cfc7000.htm Its called an HVAC table only for sheet metal. I'd like to upgrade to cut 1/2" steel and AL sheets
The torch head clamps to a shoe with roller balls a couple inches away in all directions. The whole shoe is on a slide with an air cyclinder to retract. When running, you just drop the shoe on to the work and turn on the torch. height of the torch can be adjusted by unclamping and sliding, only when the torch is off.
In reading other threads I see Z axis ball screw and other devices for raise/lower of torch. What advantages to this over the simple setup I have? In other words do I need to upgrade here?
