About DGF Engineering
Precision machining, end to end.
From a single prototype to ongoing production supply, DGF combines CNC and manual machining with practical engineering support.
CNC Milling
3 and 4-axis CNC milling for complex prismatic components, housings, brackets and plates — held to tight tolerances across a wide range of materials.
View CNC Milling details
CNC Turning
CNC turning of bushes, shafts, pins and fittings, with driven tooling for cross holes and flats. High repeatability from prototype through to production.
View CNC Turning details
Manual Machining
Skilled manual milling and turning for one-offs, modifications, jigs and rapid turnaround jobs where a CNC programme would slow things down.

Prototyping
Proof-of-concept and prototype components with practical input from experienced engineers to refine your design before tooling up for production.
