Wire Erosion – Impeller Splining
Project Name: Wire Erosion – Impeller Splining
Industry Sector: Mining, Dredging etc (Slurry Collection)
Type of Work: Wire Erosion
Our clients required large quantities of impellers. An impeller is a rotor that is part of a centrifugal pump. It is used to increase the pressure and flow of a fluid. It accelerates the fluid outwards from the centre of rotation.
Each impeller can have an impeller spline. Inside the impeller where the drive shaft fits into, there are gear like teeth which are called splines. At Cheshire Wire Erosion our task on this project was to create the impellers with the splines, this involved impeller splining. Our clients required a critical
Work Carried Out:
We used two of our “wire” machines in order to complete the task. This included the AG 600L and the AG 600LH. Because this EDM range of machines features rigid linear motors this maximises cutting ensuring accuracy and precision engineering so we can meet your requirements to your exact specifications.
With this project, to ensure we achieved the critical surface finish, 3 cuts were required. The first cut removed the waste piece as can be seen in one of the photographs. The secondary and tertiary cuts improved the accuracy of the cut and surface finish, due to the required fit between the male and female parts.
With wire erosion this same process can be repeated many times so an impeller can be created as many times as is needed so there is very good repeatability in size etc. Our clients were really pleased with the results and if an impeller was needed again this process can be replicated easily and efficiently.
