Computer Numerically Controlled (CNC) punching plays a significant role in sheet metal manufacturing, delivering high accuracy, speed and competitively priced manufactured metal components and parts.

Machines can punch many shapes, from simple circles or rectangles to overlapping geometrical 3D designs that can allow for increased flexibility in the fabrication of sheet metal components.

Our CNC controlled punch and laser combination machines are capable of even more complex geometry without the need for extra tool changes or increased set up costs.

CAD and RADAN software is network linked to the CNC cutting machines at KMF to assist with working out the most efficient layout and processing of sheet metal to fabricate the required components.

This ensures that 'nests' of parts are utilised to the highest levels of efficiency to minimise expensive material wastage and ensure fast cost-effective delivery times.

The sheet metal CNC punching department at KMF Precision Sheet Metal includes a very broad and impressive range of metal punching and laser cutting machines.

CNC punching equipment at KMF includes Trumpf TC sheet feeders, Trumpf TV Trulaser machines and tool sharpening facilities. A complete plant list can be viewed here.

Stopa storage towers are also used to feed our CNC punching machines. Each tower is capable of storing 90 tonnes of raw sheet metal, ready to be processed by the Flexible Manufacturing Cell system that gives us a 60% increase in efficiency over conventional sheet metal CNC punching machine systems.

CNC punching machines at KMF can handle an extremely broad range of metals, including CR4 (mild steel), zintec, galvanised steel, aluminium, stainless steel, copper, brass and pre-coated steel (Plastisol).
