Spark Erosion

A solid electrode typically manufactured from either copper or graphite is used Spark Erode a desired shape in the work piece.
All the electrodes other than diameter tubing and tapping electrodes are manufactured by Twin Brook Engineering.

Our Capacity;

Maximum work piece height 450 mm (fully submerged)
We use both Graphite & Copper electrodes.
4 axis machining including a rotating ‘C’ axis to achieve a specified size to within 0.005 mm
We can spark erode threads.
Utilising the ability to machine in every direction it is possible to produce the most complex and intricate shapes in small cavities.
Surface finish of 0.4 Ra can be achieved.
