CNC stands for computer numerical control. CNC punching is a computer programmed and controlled method of creating a hole, aperture or ‘cut’. By forcing a punch tool through the chosen material into a mating ‘die’ a hole or cut is formed. The slug or scrap is forced through, leaving the aperture in the material. Depending on the complexity of the requirements, a CNC punching machine can typically deliver around 350 punches per minute.
CNC punching offers several advantages over other profiling methods:
Speed: With up to 350 ‘hits’ per minute, punching is a high-speed, efficient and cost-effective method of manufacturing components.
Flexibility: As well as producing flat components, 3D forms can be produced in the material such as louvres, dimples, embossed logos and hooks making CNC punches versatile.
Efficiency and cost-effectiveness: Many punches can perform tapping and countersinking in situ, eliminating the need for secondary operations. They often have an internal quality detector to identify deficiencies and stop punching, reducing waste material.
Non-thermal: Punching is a non-thermal process, so it does not produce any Heat Affected Zone (HAZ) in the material, unlike other manufacturing methods.
At Unifabs, our machines are capable of punching a range of metals including: Mild Steel, Stainless Steel, Aluminium, Pre-Galv, Zintec, Copper. Contact us to discuss your CNC punching requirements.
