CNC Turret Punching Service
CNC turret punching creates shapes in sheet material by successively punching a series of basic shapes such as circles and rectangles. The basic shapes are selected from a rotating turret under CNC control.
Whether you need a single part, batch of prototypes, or full production order, eMachineShop will turn your design into fully machined, end-use parts!

CNC Turret Punchingis a lightweight, non-magnetic, silver-colored metal that can be formed into almost any shape. It can be rolled into thick plates for armored tanks or thin foil for wrappers. It can also be drawn into wire and made into cans.
Pure aluminum is soft and has limited strength. Small amounts of elements such as copper, magnesium and/or zinc are added to increase strength.
- Cost-effective method for cutting sheet metal in moderate to long runs.
- Edges are usually very good due to the shearing action.
- Turret punching can produce almost any 2D shape including cutouts.
- Makes a wide variety of parts
- Faster per stroke than a heavier tool press
- Offers features such as louvers, offsets, countersinking, and embossed features
- Combines many tools into one
- Replace outside arcs such as rounded corners with chamfered corners
- Reduce the number of different hole sizes
- Use of hole sizes corresponding to stock tooling
- Request custom tooling for high volume runs
- Avoid thin fragile shapes
- Warping may occur if many holes are punched or much material is removed from the sheet
- Minimize use of very small holes
- Bottom side features may have a few thousandths of an inch more material than the top dimensioned side
- Some edges may show minor signs of the successive punching process, less so on the bottom side

Sheet Metal Enclosure
One of the most popular aluminum alloys used in sheet metal fabrication. It is readily bent, punched and sheared.
Known for its high corrosion resistance, especially in ocean water. Common applications include marine and aircraft equipment, fuel lines, street lights, household appliances, flooring panels, and railings.
Used in applications requiring high strength to weight ratio, and has good fatigue resistance. It is not weldable and has average machinability.
Corrosion resistance is poor. Widely used in aircraft structures, especially wing and fuselage structures under tension.
Has generally good mechanical properties, and is heat treatable. Highly weldable although strength near welds can be diminished by up to 30% if not subsequently heat treated.
Mostly used in extruded shapes for architecture, including window frames, door frames, roofs, piping, tubing and furniture.
Strong, with good fatigue strength and average machinability, but is not weldable and has limited resistance to corrosion.
Cost is relatively high compared to other Aluminum alloys. Often used in aircraft including wings and fuselages, rock climbing equipment and bicycle components.
