EDM Hole Drilling can be used to create cooling holes to produce a jet of cold air which enable aircraft blades to function above the material’s melting point.
A&M’s hole drilling delivers a fast production turnaround thanks to our 24-hour programming.
We can use electrodes from 0.3mm to 3mm in diameter and up to 350mm in Z height.
CNC operated option with capacity for pieces up to 300 x 200 x 300mm.
A manual Bridgeport miller enabling us to hold large workpieces. We use copper electrodes to fast hole drill multiple work piece in materials such as inconel or titanium.
EDM Drilling Frequently Asked Questions
EDM drilling stands for Electrical Discharge Machining drilling. This refers to a reductive machining method which creates holes in a workpiece through spark erosion. A spark is created between the rotating tube electrode (which acts as a drill), and the conductive workpiece to erode away localised areas of the workpiece, creating highly accurate, deep holes which often cannot be achieved with a traditional drill.
