Infra-Metal’s plate burning capabilities offer two different varieties each with its own set of advantages to the customer.

CNC Hi-Def Plasma Cutting

A process used to cut steel and aluminum to a desired shape utilizing a plasma torch.  This process uses an electrical arc that is formed through an inert gas or compressed air turning that gas to plasma.  The plasma heats the metal to its melting point and blows it away.  The plasma burning machine utilizes its’ CNC capabilities to cut the desired shape.  The CNC controlled machine is driven by a program that is prepared on site from a customer supplied drawing from either .dxf or .dwg files, or from a hard copy blueprint.

The Hi-Def Plasma cutter uses a tighter nozzle than standard plasma cutting to concentrate the plasma arc, resulting in a higher tolerance finished product that requires little or no edge grinding.  Two plasma torches, one of which is a bevel torch, and 2 oxy-fuel torches, and a drill head are mounted on the machine.

Other operations performed on this machine are scribing items such as part numbers, centerlines, bend lines and center marks, to name a few.

Specifications:

Oxy Fuel

  • Burn up to 6” thick with 8 torches.
  • Can accommodate plates up to 10′ X 73′

Plasma

  • Cut plate up to 3″ in thickness
  • Can accommodate plates up to 17’ x 65’
  • Beveling up to 45 degrees and 2” thick.  Bevel types are A, V, Y, X and K and can be cut on complex profiles, both outside and inside contours.
  • Drilling hole sizes range from 1/8” to 2-1/2” diameter.  The machine has a 12 station  tool changer and can drill up to 4” deep.
  • Other operations that can be performed are tapping, countersinking and counterboring.
  • ProNest nesting software and AutoCAD

Oxy Fuel Plate Burning

Utilizing oxygen and propylene this process can burn through plate several inches thick.  Driven by CNC (Computer Numerical Control) part programs it can produce shapes made to specific dimensions.  Oxy-fuel is usually used to cut thicker material.  Hi-def plasma gives a tighter  tolerance and smoother cut and oxy-fuel burned material usually needs edge grinding as a secondary operation to finish the processing.
