Spark Erosion

Spark erosion allows the machining of hardened conductive materials, to create intricate shapes and forms. A shaped electrode erodes material, creating a shape opposite to that of the electrode.

Our largest spark cutting dimension is 1200 x 650 x 500 mm and 5 tons in weight. Our machines give us the flexibility to use SYSTEM 3R and EROWA work holding systems.

We have the facility to tool change up to 15 stations, for multi-feature sparking in one operation. All our spark eroders offer the capability for multi-axis cutting in all three axes simultaneously for complex jobs.

All have on-board technology to use multiple electrodes materials e.g. copper, graphite and copper tungsten, allowing us to spark multiple work pieces in materials such as inconel or titanium.

 

All our spark eroders have C Axis capabilities, allowing us to spin the electrode and achieve greater tolerances and precision.

Bespoke Spark Eroding Solutions

Spark eroding is a specialist skill and A&M has specialist engineers with over 100 years collective experience, enabling us to provide bespoke spark erosion solutions to create large, long or irregular shapes.

Spark EDM allows work on very small pieces where the pressure of conventional cutting tools could damage the part and delivers a finish to the tightest tolerances.

Spark Eroded 3D Cylinder

We pride ourselves in finding commercial solutions to challenges. Much of our spark erosion work requires us to develop a bespoke engineering solutions. For example, on an aerospace engine component, we spark eroded 3D form to encircle a cylinder, something that had not been done before.

 

CAD Programming

We developed the CAD programming to generate the tool paths to machine the part successfully and cost effectively.
