CNC punching

Prototypes to full sheet metal work are made easy with Constant’s CNC punching machine


CNC Punching

Our CAD Design Engineers onsite will use their years of experience to determine the best punch press option for your project and costs.

Using the Trumpf TruPunch 3000, suitable for small batch runs and large scale production runs, our typical punching jobs can be as simple as a square, or complex profiles with forms. Classic examples of job runs include ventilation products, brackets for gaming machines and components used on earth moving machines.

The Trumpf punch machine benefits from low cost tool set ups and cost effective running costs. Twinned with automation to load and unload both raw material and waste material our services can really benefit bottom line part costs, especially considering our ability to run unmanned production, “lights out”.

Range of operations including: piercing, nibbling, embossing, extruding, slotting and recessing, louvering, coining, countersinks, forming tabs, creating ribs and creating hinges.

  • Specialised tooling can be purchased if needed
  • With our STOPA we can store and automate upto 70 tonnes of sheet metal
  • Unmanned production ability for overnight production
  • Material thickness from 0.5mm up to 8mm
  • Punching accuracy of 0.02mm
