Kennametal has developed a 3D printed stator bore tool specifically designed to meet growing customer demand for lighter weight tooling solutions used to machine components for hybrid and electric vehicles.
E-mobility components are typically machined on smaller, low horsepower CNC machining centers that require lighter weight tooling solutions. Kennametal’s 3D printed stator bore tool weighs half that of the conventionally manufactured version, while still meeting accuracy, roundness, and surface finish requirements for aluminum motor body boring.
“The main bore, that houses the stator of an electric motor measures approximately 250 mm in diameter (9.84″) and approximately 400 mm (15.74″) in length, with a smaller bearing bore at the bottom,” said Harald Bruetting, Manager, Program Engineering. “When manufactured using conventional means, a reamer for this type of application would weigh more than 25 kilograms […]
