How turret punching works

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.


Turret punching is a 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. Example applications include: Custom EnclosuresCustom Metal BracketsCustom Robot PartsCustom washersCustom wrenchesCustom Front PanelsCustom Sheet Metal BoxesCustom Motorcycle PartsCustom Auto PartsCustom Toy Parts, mechanisms and chassis.


Punching is commonly applied to: AluminumStainless SteelSteel, and Brass.

Cost optimization

  • Replacing outside arcs such as rounded corners with chamfered corners

  • Reducing the number of different hole sizes 

  • Minimizing use of complex curves

  • Use of hole sizes corresponding to stock tooling

  • Requesting custom tooling for high volume runs

Design Considerations

  • 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.
