Wire Erosion

Wire erosion guidelines

Six large Hitachi Q range wire eroders give us a wedm potential of over 1000 hours per week cutting time. This means that nearly everything is wire eroded where possible, enabling exact duplication of parts in the event of tool damage. Our most recent addition is a Hitachi 8Q, possibly the largest machine in the UK. Cutting envelope is 1000 x 800 x 500 coupled with an AC generator, and 45kg despooler, means that large parts can be cut continuously for days on end. Four machines are capable of 1000 x 600 x 500 in a normal setup, and the 6th machine has an AC generator and a smaller bed, for multi pass cutting.

We also have a remote table setup which enables us to carry up to 2 tonnes. This means we can do straight line cuts up to 3m in certain cases, and gives us the facility to split up large rings as used in the turbine industry.

With the support of a fully operational tool room, we can construct our own jigs and fixtures, and modify machine parts to overcome almost any problem.
