What is CNC Punching?
CNC punching is a sheet metal punching process. It uses a CNC punch press to create holes and shapes in metal sheets. It’s used for manufacturing metal parts that need high precision and repeatability. For example, such as perforated sheets or punched parts. By using CNC punching machines, we make sure that every part is crafted with exact tolerances. That makes it great for industries requiring consistent metal products.
The punching service is cardinal for industries like automotive and aerospace, where complex designs and high-volume production are required. With CNC punching capabilities, we offer services that bring down material waste while keeping fantastic speed and accuracy.
What Materials Can Be Used in CNC Punching?
We provide custom metal punching services for a broad range of materials, ensuring we can meet your metal punching requirements. Our CNC punching machines can handle different thicknesses and types of metal sheets, including:
| Material | Applications | Thickness |
|---|---|---|
| Mild Steel | Structural parts, chassis, automotive | Up to 1/4″ |
| Stainless Steel | Medical devices, food processing | Up to 1/4″ |
| Aluminum | Aerospace, automotive, electronics | Up to 1/4″ |
| Brass | Electrical connectors, musical parts | Up to 1/8″ |
| Copper | Heat sinks, electrical applications | Up to 1/8″ |
| Precoated Materials | Architectural facades, signage | Up to 1/4″ |
Our machines accommodate metal sheets of various materials, ensuring flexibility and precision for any project. Whether you need carbon steel, stainless steel, or aluminum, our punching equipment is equipped to handle all your needs.
What Features Can Be Created with CNC Punching?
Our CNC punching services enable the creation of complex features in sheet metal that would otherwise require multiple manufacturing steps. These include:
- Louvres: Features that allow for airflow, commonly used in ventilation systems and electronics enclosures.
- Embossing & Dimples: Ideal for metal fabrication projects that require branding or structural reinforcement.
- Countersinks: Creating recessed areas in punched holes to fit fasteners or screws.
- Tapping: Allowing for threaded holes to accept fasteners or bolts.
- Cluster Tool Punching: A method for punching multiple shaped holes at once, significantly reducing production time.
These punching capabilities ensure that we can create complex shapes and parts to meet your specific needs, while also providing high precision in every punch.
What is the CNC Punching Process?
CNC punching involves several precise steps to create the desired metal parts. Here’s an overview of how the punching process works:
- Material Preparation: The metal sheet is loaded into the machine, secured with clamps to ensure it stays in position.
- Tool Selection: A punch tool and die are selected based on the material type and the required hole size.
- CNC Programming: The CNC punch press is programmed to move the punch and die into position, where they meet to shear the material.
- Punching: The punch descends, shearing the material to create a hole or cutout.
- Post-Processing: After the holes are punched, the punched parts may undergo deburring or other finishing processes to remove sharp edges.
This method of metal punching ensures that parts are produced quickly and efficiently, with minimal waste and high repeatability.

What Our Clients Say
CNC Punching FAQs
Punching in fitting refers to creating holes in sheet metal parts to allow for fasteners or other components to fit together, commonly used in the automotive and electronics industries.
A CNC turret punch is a machine tool that uses a rotating turret to hold multiple punch tools, allowing for fast and flexible tool changes during production, increasing efficiency.
The punching process involves using a punch and die to create holes or shapes in sheet metal. The punch is pressed into the metal, shearing the material and leaving behind the desired cutout or hole.
