CNC Turret Punching

Thu, 10 Jul 2008

CNC Turret Punching creates various forms in a sheet material by successively punching a series of basic shapes. Parts made include brackets, enclosures, front panels, assorted mechanisms and so on. CNC Turret Punching generally requires only software tooling. Customers can reduce costs slightly by minimizing the number of different hole sizes and avoiding shapes that cannot easily be made using circles and rectangles such as outside arcs, thin slots, inside angles under 90 deg and arc-to-line inside angles under 180 degrees. A laser cut part may be lower in cost when the design has splines or many convex or complex arcs.

CNC Turret punching creates sheared edges that may have slight rounding on the top side and a slight burr on the bottom side. The bottom side of a CNC turret punch part tends to have less evidence of the nibbling process than the topside. For best appearance in production runs clients can request custom punches to the shape of the cutouts - especially for rectangular and oblong slots.

CNC Turret Punching machines are traditionally programmed using a set of commands known as G-codes. G-codes represent specific CNC functions in alpha-numeric format.

Turret punching is just one of the many machines available to users of eMachineShop. This includes free 3D CAD software, online learning tutorial videos, and the ability to click and order custom designed machine parts online without going through the many steps of dealing with a conventional machine shop.
