S.P.F. (single point forming) is a process where sheet material is incrementally dented into a desired three dimensional shape, usually by a round-tipped tool. This is the CNC equivalent to hammer formed metal.
A CNC Tube Bender is a computer controlled machine that can create a series of complex curved bends in pipe material. This tool is capable of bending pipe in a variety of radii and directions.
A CNC Roller is a computer controlled machine that can create specific curved bends in sheet and stock material. It is comprised of 3-4 rollers. Rollers can be repositions. The diameter and position of the rollers determine the smallest radii possible in the bend.
A CNC Punch Press is a computer controlled machine that uses pre-formed dies to punch specific shapes out of sheet material (usually sheet metal). These machines can generate single cuts or cuts organized in a designer determined pattern.
