Wire Erosion

Electrical discharge machining using the technique of wire erosion can deliver much greater accuracy than with conventional EDM techniques. Using wire erosion we can achieve accuracy between 0.004mm and 0.040mm not just faster, but more economically too. A combination of CNC control and highly sophisticated computer design technology enables complex work to be carried out and the requirements of our customers to be met, if not exceeded. At our facility in Sheffield we have seven wire erosion machines which are top-of-the-range. For further information on our machine capacities please visit our capacity website page. On our website you can also view examples of our EDM work located on our examples page.

Spark Erosion

With solid sink spark erosion we expect to be able to deliver accuracy in between 0.020mm and 0.050mm and to be able to do this faster and more economically than with the conventional machining techniques. We find that our spark erosion capabilities are often required when work pieces require rescuing i.e. when a drill, tap or another tool has broken but cannot be removed from the work piece. We can nearly always remove embedded stubs with our precision facilities; providing a much better alternative to ending the progress of your entire project.

Electrical Discharge Machining

Our specialism is in EDM or electrical discharge machining here at Erodatools Ltd and we have over 40 years of experience in the industry having served a wide variety of sectors including aerospace, nuclear energy suppliers, defence, marine, surgical, military, automotive, railways and oil/gas exploration. Any EDM work we carry out is of a consistently high standard due to being an ISO 9001 2008 accredited company. We have the capacity to be able to handle large and heavy work pieces up to a weight of 2.25 tonnes. For more information, please visit our website, or, give us a call and we’ll be happy to help.

Ultrasonic Test Reference Standard

A non-destructive process, ultrasonic testing is a technique that allows us to examine heavy duty materials for faults which are internal, without having to take them apart. How does it work? We use a technique which sends high frequency sound energy through the material and any faults or cracks are detected by irregularities shown up by the resulting sound wave. These techniques are also used in order to determine how those materials would react in certain circumstances. For more information on our ultrasonic test reference standards please visit our website or contact us directly and we’ll be more than happy to assist.
