Utilising the design information supplied from the tooling model, impression forms are rough machined. High speed Ethernet connections communicate gouge free, accurate toolpaths produced by industry leading software to the vertical machining centres.
All impression forms are finish machined after heat treatment to ensure their accuracy leaving spark erosion for the deeper finer detailed area's.
We use Haimer and WTE 'Shrink Fit' technology for spindle tooling.
5 Axis machining.
CNC and manual spark erosion machines utilising CNC orbital heads give an improved surface finish while the System 3R Macro pallet system ensures fast and accurate transfer of electrodes between milling and erosion machines.
Inspection of impressions and spark erosion electrodes are undertaken using Autodesk Powerinspect 'on machine verification' software using a Renishaw OMP60 probe. The probe and software are used to compare the machined 3D surface back to the CAD model and report on any deviation. If the impression or electrode requires additional machining this can then be recut on the machine and checked again for accuracy.
