Machining deep, precision slots in ductile iron is one of our core capabilities — especially for critical hydraulic vane pump cores.
These pump cores start on the lathe. We turn the outer diameter and machine the central bore first. After turning, parts move to our 4th-axis CNC mill for slot work.
The internal slots guide pump vanes, so tolerances are non-negotiable. For this tough ductile iron application, we use a Walter Tools indexable slotting mill. Similar to a slitting saw, its carbide inserts resist abrasion from ductile iron while maintaining tight slot tolerances.
Our process uses rough hogging to remove bulk material, then a final finishing pass to clean up slot side walls. This two-step method delivers consistent surface finish and accurate dimensions for every vane slot.
We specialise in precision CNC machined ductile iron components for hydraulic and industrial applications. All parts are manufactured strictly to customer drawings.
