Wire EDM Machining of Internal Splines

The electrical discharge machining services we offer at Enterprise can be used to produce precision single piece or low volume components for a variety of applications. The project highlighted here consisted of the machining of an internal spline that was used in an overhead crane by a customer in the new equipment industry. The spline is constructed of R4140-HT chrome-moly steel with an outer diameter of 11.811”, an inner diameter of 10.770”, and a length of 13.625”.

This customer is local who called on us to perform their post manufacturing machining work. EDM processes are ideal for many post-manufacturing applications because they provide the ability to perform precision machining on hardened metals. For this project, dimensional tolerances as tight as ±0.0005” was held at critical locations. This was a rush order for a single piece that was completed in two days. As a result of our responsiveness and quality of work on this project, the customer has contacted us regarding several additional machining projects.
