CNC punching has been the backbone of sheet metal fabrication for over 50 years, and Yorkshire Laser has been providing efficient, fast and flexible CNC punching services for more than half of that.
Although CNC laser cutting technology has gained inpopularity in recent years, CNC punching presses remain a valuable part of thesheet metal fabricator’s toolbox, unrivalled for their ability to removesecondary operations such as countersinks and threaded holes, as well as beingable to insert multiple forms like louvres and knock-outs.
It’s a reliable, cost-effective option for precisionfabrication and the expert team at Yorkshire Laser is here to make it work foryou.
CNC punching involves positioning the sheet metal under the punching ram on the CNC punch press, which then punches into the metal the desired hole or form, such as:
- Centre punches
- Countersinks
- Embosses
- Knockouts
- Hinge forming
- Louvres
Today, this process is programmed and controlled by computer-aided manufacturing (CAM)software, creating parts and components for use in numerous sectors and industries, including automotive, telecommunications and power generation.
CNC punching provides exceptional precision and consistent hole placement and patterns, helping to minimise human error and produce parts with tight tolerances.
CNC punching machines can achieve speeds of 1000 hits per minute, and as punching machines are non-thermal, there are no heat-affected zones (HAZ)that need revisiting.
Punching technology can produce both flat components and 3D forms in the parent sheet metal, such as CNC punched louvres, dimples, embossed logos and hooks. This form of fabricating sheet metal also allows for tapping and countersinking, which can be produced in situ, eliminating the need for ‘secondary options’.
We operate an EML-AJ combination laser and punch machine with an automatic punch and die changer. Capable of punching, forming, tapping and laser cutting, this machine speeds up production of those items that require different manufacturing techniques. Twinned with an automated picking facility, the EML-AJ provides micro joint-free processing.
With a full toolbox of sheet metal fabrication processes available to us, we can tailor our services to the requirements of each job, providing the most effective and efficient process each time you work with us.
This tailored service means you can be sure of the best and most cost-effective solutions to your sheet metal fabrication needs. Whether this is via a laser or punch process, we’ve got you covered.
Providing exceptional customer service is first and foremost at Yorkshire Laser, and our commitment to quality and reliability is backed up by our accreditation to quality and environmental standards ISO 9001and ISO 14001.
Based near Leeds in West Yorkshire, our skilled, experienced team are here to help you every step of the way, and we offer quick quoting and fast turnaround on orders without compromise on a high-end product.
What is CNC punching?
CNC (Computer Numerically Controlled) punching is a sheet metal manufacturing process that is carried out by CNC punching machines. A CNC punch press is programmed by a computer-aided manufacturing software to manoeuvre a sheet of metal in an X-and-Y direction. This placement accurately positions the sheet metal under the machine’s punching ram. When ready and in position, the punch presses will punch a hole or form into the material.
What materials can be used in CNC punching?
CNC punching can be carried out on a wide range of materials, including mild steel, galvanised steel, pre-coated steel, stainless steel, aluminium, brass and copper. Different sheet thicknesses and finishes can be processed to create precise components for many industries.
How does CNC punching create metal forms?
CNC punching plays a vital role in sheet metal manufacturing by using an electric ram to form shapes such as louvres, dimples, rectangles, knockouts and embossed features. This method enables both flat and 3D metal forms to be produced quickly and accurately. Press brake bending can also be used in combination with CNC punching to form more complex components.
What are the advantages of CNC punching for high-volume production runs?
For projects that involve high-volume production runs, CNC punching offers exceptional speed and productivity. With high-speed capabilities and automatic tool changes, it reduces downtime and delivers consistent results across stacked metal sheets, making it ideal for cost-effective component manufacturing journeys. Our advanced technology ensures consistency, reduces waste and improves efficiency across different project sizes.
Why is CNC punching still important in modern fabrication services?
Although laser cutting is increasingly popular, CNC punching remains essential in subcontract sheet metal fabrication and engineering. It enables threaded holes, countersinks and other features to be produced in situ, reducing secondary operations and supporting more efficient fabrication services. Combined with processes such as spot welding and assembly, CNC punching helps clients meet deadlines and bring reliable products to market.
What industries benefit from CNC punching capabilities?
CNC punching is used in component manufacturing journeys across sectors such as automotive, telecommunications and power generation in the UK. The ability to process different materials and shapes means CNC punching enables many services and applications, from prototypes to large-scale projects. With years of industry experience and strong capacity, Yorkshire Laser can discuss your needs and ensure your project is delivered with precision.
How has CNC punching technology evolved?
From the first CNC punching machines to today’s continually upgraded systems, technology has transformed productivity in sheet metal punching. Modern machines combine laser cutting and punching in one process, with automated tool changes and integrated threading that streamline fabrication from start to finish. Our investment in advanced technology helps improve quality, maintain consistency and save clients time and money.
Can CNC punching be combined with other fabrication processes?
Yes, CNC punching can be integrated with other processes such as press brake bending, inserting, stud welding, spot welding and final assembly. This approach enables a broad range of shapes and designs to be created, ensuring your project benefits from flexibility and efficiency at every stage of its manufacturing journey.
