Compound Curves In Sheet Metal

It s the very of what we do and we do it very well.

Compound curves in sheet metal.

The curved pieces would be a 6 radius 90 degrees by 2 to 4 ft long. A foot operated control allows speed and power of strokes to be varied. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. Do you have a project which requires compound curves variable radius bends interfering parts or which has other complication.

Metals have an elastic limit that needs to be exceeded in order to get the plastic flow to occur to effect this thickness change. Sheet metal is metal formed by an industrial process into thin flat pieces. Works sheet metal into compound curves rapidly but not as smoothly as does the english wheel. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

The wheel pants often installed on volume produced light planes are made by fastening together right and left halves made of aluminum formed to shape by matching dies installed in a type of machine called a drop press. The corners would be the same radius 90 in 2 directions. Common sense says that the graceful compound curves to be seen in them could hardly have been achieved by a sheet metal shop doing heating and ventilating ductwork. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

With thirty six years in the that s going to be tricky to make business we ve learned a few things we. Thicknesses can vary significantly. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Creating compound curves in sheet metal is about changing the thickness of the metal.
