What is CNC punching?

Date: 05/11/2019

SHEET metal fabrication is increasingly reliant on Computer Numerically Controlled (CNC) laser cutting.  Here at Yorkshire Laser we use it extensively for its versatility, accuracy, speed and cost efficiencies.

What is CNC punching?

CNC (Computer Numerically Controlled) punching is a sheet metal manufacturing process that is carried out by CNC punch presses.

A CNC punching machine is programmed to manoeuvre a sheet of metal in an X-and-Y direction. This placement accurately positions the sheet under the machine’s punching ram.

When ready and in position, the punch ram will punch a hole or form into the material.

At the same time CNC punching allows us high tension with very little distortion compared to its CNC laser cutting equivalent.

It means that we can create shapes and holes including:
• Louvres
• Centre punches
• Countersinks
• Embosses
• Knockouts
• Hinge forming

This is important to our customers who need very specific sizes of shapes in enclosures that protect high value products such as oil lines or telecommunications networks against adverse climates.

What are the benefits?

Yorkshire Laser operate an Amada Vipros 368 King. This is a 30 ton, 58 station hydraulic machine that comes complete with a 1500mm deep throat, programmable ram and a fully brushed table.

This enables us to process sheets up to 1500mm wide.  With an incredibly high hit rate, perforated parts like grills can be made much cheaper and with much less distortion than would occur with the laser treatment.

Another bonus is the ability to tap formed holes directly on the machine, whilst the programmable ram allows us to form shapes in material with amazing accuracy and consistency.

The ability to offer various methods allows us to provide a more personal and tailored service for our customers’ complete satisfaction.

As a traditional fabricator delivering high quality products to some of the most vulnerable, high value industries in the world including offshore, gas, telecommunications, power generation and medical we’ve embraced laser cutting but not at the cost of every alternative including CNC punching.
