Alternative Precision Machining Processes: Wire Cut EDM Machining
A simple manufacturing process in principle, wire cut edm machining is incredibly useful for a number of machining situations which might otherwise pose a conundrum. The machining of brittle & hard-to-machine materials, hardened metals and alloys, thin walled components requiring a last operation of machining and small internal holes and apertures are all easily handled by wire cut EDM machining.
Wire EDM – in terms of an electrical discharge’s erosive properties, was first discovered in 1770 by Joseph Priestly, an English physicist. It wasn’t until 1943 that two Russian scientists developed this erosive effect into something much more useful for the machining of Tungsten – a notoriously difficult to machine material. This machine was known as an R C type machine (resistor/capacitor). During the same period a team from the USA were developing a similar machine to extract broken taps and drills from aluminium cylinder blocks and castings. These early machines were basic and of course, unreliable.
During the 1960’s and 70s, EDM – both in terms of spark erosion and wire cut EDM machining, received a spurt of development towards the first CNC programmable EDM machines. Reliability improved and during this time, Di-Spark – operating as a tool making company, made investments into this new and innovative technology – something we’ve been doing ever since.
In 2016 Di-Spark Ltd operate as a sub-contract precision machining company, operating our around-the-clock facility over 40,000 square feet, housing machining cells specialising in 5 axis machining, CNC mill-turn, large & heavy machining, spark EDM and wire cut EDM machining cells.
Our wire cut EDM machining cell sports the latest EDM innovations, features such as CNC control, advanced power features for clean-cut machining and excellent surface finish.
