Materials Science N.W. Laboratory Spark Erosion Machine Mk4

Laboratory Spark Erosion Machine

The Laboratory Spark Erosion Machine performs sample cutting by means of electrical discharge machining (EDM), a non-traditional machining process that erodes the workpiece material using a series of discrete electrical discharges (sparks).

Detailed Description

As the workpiece and tool material are not in direct contact during EDM, the Laboratory Spark Erosion Machine can be used to prepare sub-mm size samples of materials that, as a result of their mechanical properties, prove difficult to machine using traditional methods.


The Laboratory Spark Erosion machine is particularly effective when used for the production of 3mm TEM disks using a tubular electrode and when used with a wire cutting stage to produce thin material samples devoid of the deformation characteristic of traditional machining processes. The setup is currently being implemented for hot-cell use.
