CNC punching 

CNC punching for high speed and low cost 

At Dymond, we use our CNC punch press for high speed, low cost production of large quantities of metal work.

CNC stands for Computerised Numerical Control. Pre-programmed software and code controls the manufacturing process, that is, it controls the movement of production equipment.

We use the CNC punch press when your design requires multiple ‘cut-outs’ or holes in sheets of metal. This is because we understand that punching is a cost-effective way of achieving this.

Dymond uses a turret press to turn out multiple shapes at low cost and high speed with a great degree of accuracy and consistency. If you need large quantities of relatively simple items it’s a more competitive option than laser cutting.

The CNC punch press is based on the concept of a single station power press, but on a larger scale, our turret press has 16 tool stations.

Dymond generates a CNC program directly from your drawings. This controls the tool station and the movement of the metal sheet with great accuracy.

The punch press forces a hardened steel, or tungsten carbide punch, through the metal sheet into the corresponding die. We keep shearing to a minimum, as the die supports the sheet from below, therefore we achieve a clean-edged hole. As the sheet moves through a sequence of pre-programmed movements, shapes are cut out of the metal. These can vary from simple holes to complex curves according to the program. We can combine multiple dies can which produce more elaborate shapes.

Dymond, we aren’t punching above our weight!
