CNC punch machine (NC turret punch) is used for cutting purpose as well with tools, it is developed for high flexibility and efficient processing of metal stampings.
Those machines are typically equipped with a linear die carrier (tool carrier) and quick change tools,the main areas of application are for small and medium runs.
Today the method is used where the application of lasers are inefficient or technically impractical. CNC is the abbreviation of Computer Numerically Controlled.
CNC punch is normally used as the cutting operation for a sheet metal part when the sheet metal parts is made from thin material normally lower than 3mm THK (11GA).
CNC punch machine is working with tooling which is able to trim or form different features as per the design.
CNC punching is normally used when the quantity is large to save manufacturing cost.
Compared with laser cutting machine, it has below advantages:
-More cost saving, as only electricity needed.
-In some cases, it is more efficient than laser cutting. Like when the sheet metal requires many holes, slots etc.
-It is able make some features that can not be made by laser cutting like knockouts, bridges, louvers, ribs, extruded holes etc.
