Leading UK concrete drilling and wire sawing engineering firm Holemasters has completed one of its more challenging wire sawing projects to date. The project being to dismantle a CFM56-3 jet engine on behalf of SWB Steel Services who specialise in disposal of complex metallic materials.
Because jet engines, by their very nature, have to withstand extreme heat they contain a variety of special alloys. These alloys effectively resist the very high operating temperatures and rotational speeds with an intrinsic need to be lightweight.
The specific challenge was to establish a single wire cutting method to deal with all these different materials.
In addition was the need to devise a cutting system which could be easily transported to where the jet engines were located. The system also had to cope with the irregular shape of the engine, and the components within the engine as they were released during the cutting process.
