Sheet Metal Punching Services on CNC Turret Presses

Dynamic Design & Manufacturing (DYCO) provides sheet metal punching services on CNC turret punch presses for both custom and standard shapes. CNC punching is a computer-controlled process that strikes holes, slots, and other geometric features into a sheet in seconds. Each job combines a punch, a die, the sheet, and a program that tells the press which tool to use and where to hit. For flat parts with many holes, our Amada and Trumpf turret presses are the most efficient way to produce them, and every punched blank can move straight into forming, hardware insertion, and welding as part of our precision sheet metal fabrication services.

CNC Punching vs. Stamping

CNC stamping is best suited for large volume production runs where 5,000 or more parts are made in one run. CNC punching is often utilized for smaller volume production runs where costs can be optimized for the lower runs. This process is the best way to punch parts without investing in high-priced unique tooling.

Because a turret press works from standard punch and die sets, most hole patterns and cutouts need no part-specific tooling. That keeps setup cost low for prototypes and short runs, and an engineering revision that moves a hole only requires a program change. Our Trumpf TruMatic 6000 pairs its punch head with a 3,200-watt CO2 laser, so contours that no standard tool can make are cut in the same setup.

Frequently Asked Questions

What is CNC punching? +

CNC punching is a computer-controlled process where a turret punch press strikes a sheet with a punch and die to create holes, slots and other shapes. A program tells the press which tool to use and where to place each hit, so complex hole patterns can be produced in seconds and repeated across every part in the run.

When is CNC punching more cost-effective than stamping? +

Stamping is best suited to large runs of roughly 5,000 parts or more, where the cost of a dedicated die is spread across high volume. CNC turret punching uses standard punch and die sets, so prototypes and short to mid-volume runs avoid the cost of custom tooling.

How thick can sheet metal be for CNC punching? +

Our Trumpf TruMatic 6000 punch and laser combination machine handles sheet up to .300" thick and up to 121" x 68". Practical thickness on each press depends on the material and the hole size, so send your print and our team will confirm the best machine for the part.

What tolerances can your CNC turret punch presses hold? +

Our Amada Merc 722 is rated for positioning and repeatability of plus or minus .001". The Trumpf TruMatic 6000 is rated for plus or minus .004" positioning accuracy with average repeatability of plus or minus .001". Final part tolerances also depend on material and downstream forming.

Can punched parts be formed, welded and assembled in house? +

Yes. Punched blanks move directly into press brake forming, metal rolling, hardware insertion, TIG, MIG and laser welding, and assembly in our Niwot, Colorado facility, so one supplier manages the part through every operation.

Is DYCO ITAR compliant? +

Yes. Dynamic Design & Manufacturing is ITAR compliant, and our manufacturing processes are AS9100D and ISO 9001:2015 certified, which supports punching work for defense and aerospace programs.
