Spark Eroding


The process of spark erosion enables us to machine hardened or difficult to machine conductive materials to create shapes and forms that couldn’t be achieved with conventional CNC/Manual milling or turning

We have specialised in spark erosion since we started back in 1992 and have 5 full function CNC machines all with C axis and annually calibrated to Nadcap standard, our largest can take components  x y z   1000x700x400mm with a tank size 1200x800x400mm .

We have a very advanced Mitsubishi machine that has a special generator that enables us to spark erode Carbide

All work is carried out under AS9100 Rev D quality system ensuring peace of mind regarding traceability, quality and delivery.
