PLATE PROCESSING

PLATE BURNING

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.

DRILLING

Drilling is the process of forming holes in steel and other materials utilizing a drill bit.  The material/drill is cooled using through the tool coolant from a reservoir in the drilling machine.  This compressed air blows away the chips as they emerge from the hole ensuring a smooth finish. They're various types of holes that can be achieved with our drill.

 

Counterbore  – A counterbore is a flat bottomed hole that enlarges an existing hole.  It is typically used when a fastener is to be used on a workpiece, the head of which must be either flush with or below the surface of the workpiece.

Blind Hole - A blind hole is a hole that does not penetrate though the plate.  This is often used when the plate is sit next to another plate or structure.

 

Reaming – Reaming is a process that enlarges a pre-existing hole, usually drilled, utilizing a special reaming tool.  This ensures a closer tolerance hole than can be achieved by drilling alone.

 

Tapping – Tapping is a process that forms threads in a drilled or reamed hole, usually for screws or bolts.  The tool used for this process is called a tap.

BEVELING

Beveling provides a smooth surface for weld prep to join separate pieces of steel.  The bevel allows for proper weld and to prevent center-line cracking.  Types of bevels include VDS (descending bevel), VAS (ascending bevel), YDS and YAS (descending and ascending with a land), X and K
