Computer Numerically Controlled (CNC) punching is a metal stamping method that uses dedicated computer software to punch press metals. The punch presses use special rams to indent forms or create holes in sheet metal using computer-aided technology to position the ram.

The CNC punching process is the best alternative to metal stamping or laser cutting for accuracy, efficiency, and cost-effectiveness. It is also versatile and can apply punch patterns to vast materials, including steel, brass, aluminum, and more. At US Metal Crafters, we provide a range of metal stamping capabilities, including CNC punching. We can handle orders for clients in a wide range of industries.

The CNC Punching Method

At US Metal Crafters, our CNC punching process involves converting 2D and 3D CAD/CAM files into computerized instructions. These instructions control the movement of appropriate tooling and press flat sheets of metal based on customer specifications.

CNC punch presses can create holes in a wide range of materials and in various shapes to produce custom designs. Common materials used for CNC punching include stainless steel, aluminum, galvanized steel, and more. CNC punching can also accommodate complex designs, with capabilities such as developing threads, folding tabs, and producing sheared edges. 

When is CNC Punching Preferred?

There are many instances when manufacturers may prefer CNC punching over alternative stamping options. These instances include:

  • When specific shapes on small parts and components are needed. CNC punching is capable of producing complex and specific shapes on smaller components. Other metal stamping processes are more suited for stamping an entire piece.
  • When producing prototypes. CNC punching is an ideal method for producing prototypes. If your application requires mass production, alternative metal stamping methods may be a better option.
  • When cost is a factor. The CNC punching process can reduce delivery times and costs, making it more affordable than other options.

Advantages of CNC Punching

CNC punching offers many benefits over alternative stamping methods. These include:

Cost-Effectiveness

CNC punching is cost-effective for both small and large production batches. It’s cost-effective because of its quick configuration, large tooling capacity, and high-speed processing. CNC punching also keeps waste at a minimum, preventing the discarding of raw materials. This saves you money.

Efficiency

CNC punching machines are fast and accurate. The machine stops punching as soon as it detects any defect to prevent further waste.

Increased Productivity

With CNC punching, there is no need to design something every time you need it. Once you choose and create a design, you don’t need to create it all over again. CNC punching removes technical and intensive manual processes, increasing productivity.
