CNC Punching

CNC Punching

At 3SI, our precision CNC punching services, with high-speed and heavy-tonnage capabilities, produce parts of exceptional quality with close-tolerance requirements.

Computer numerically controlled (CNC) punching is a plate or sheet metal fabrication process performed by a CNC punch press with hard tooling. 

The CNC punch press moves the material to the correct position below the punching ram. A variety of punching tools allow us to punch the desired shape according to drawing requirements. Our precision CNC punching services, with heavy tonnage and high-speed capabilities, produce parts of exceptional quality with close-tolerance requirements.

Through the use of our advanced 33-Ton CNC punching equipment , 3SI can process carbon steel, stainless steel, and aluminum, in sheet and plate forms, up to 60 inches wide and ¼’ inch thick.

Like all services performed at 3SI, our CNC punching services include strict adherence to our ISO 9001:2015 quality program. We perform first article, in-process and final assessments, and also conduct dimensional testing with calibrated measuring equipment. Our inspection and testing procedures ensure we are

CNC Punching Services

At 3SI, business has allowed us to provide precision CNC punching services to a vast range of industries, including:

  • Agricultural
  • Mining
  • Aerospace
  • Military
  • Construction
  • Contract manufacturing
  • High-quality components
  • Energy-Oil and Gas

While laser cutting is commonly used in today’s manufacturing processes, there are applications where this technology is either inefficient or impractical. In these applications, precision CNC punching is used as an alternative fabrication method. Our CNC punching capabilities allow us to efficiently complete fabrication for small to medium-sized runs of sheet metal components.

CNC punching capabilities are used to form sheet metal components for a variety of industries, including:

  • Agriculture
  • Construction
  • Mining
  • Contract Manufacturing
  • Aerospace
  • Military & Defense
  • Electrical Equipment & Electronics
  • Commercial Display
  • Oil & Gas
  • Transportation
  • Heating & Cooling
  • Packaging
  • Engineering

Components manufactured through CNC punching are used for a broad range of applications. For example, CNC punch-fabricated components are often used in the material handling industry, where they are found in lifting equipment, truck cranes, boom components, and frame rails. Wear parts for the mining and manufacturing industries are also created through CNC punching services. Enclosure cabinets used to protect heating and cooling equipment, electrical equipment, and electronic components are all fabricated using CNC punching.

CNC punching is a vital manufacturing process for fabricating sheet metal components quickly and efficiently. This flexible machinery is capable of producing flat and three-dimensional metal forms used in a variety of applications for numerous critical industries.
