New Energy Electric Drive | Precision Machining of End Cap Steel Bushing Holes—Ultimate Cost-Effectiveness
2025-12-05 14:54
Project Background
In the electric drive system of new energy vehicles, End cap steel sleeve hole It is a critical component that ensures the structural stability of the motor and the overall vehicle performance. The steel sleeve bore not only serves the functions of positioning, supporting, and providing reliable connections, but its geometric accuracy, bore wall quality, and machining consistency all directly affect the motor’s operational stability and service life.
The following are the difficulties in machining the steel bushing holes in the end caps:
-
The material is relatively hard and highly ductile (45). #Special Quenching and Tempering Process for Steel ) The cutting resistance is high, and the tool wears out quickly.
-
High precision level required, A two-hole design—using a fixture to clamp thin-walled parts can easily cause deformation, and high consistency is required. Precision grade IT6, roundness requirement 0.015; each part with two holes must simultaneously meet the CPK requirements.
-
High requirements for batch stability, Unstable tool life can lead to frequent tool changes, increased costs, and fluctuations in cycle time.
Considering the machining characteristics of steel sleeve holes, Ruiding selects... After the snow stops ® E320 Series Reamers This series of cutting tools has been upgraded and refined based on their original design, resulting in a unique geometric structure. With their exceptional chip-breaker geometry and blade-edge design, these tools are particularly well-suited for high-precision hole machining in steel parts. The single-hole pure cutting time is just 2 seconds, delivering outstanding value for money.
Application Cases
Ruiding Value
Ruiding will continue to provide high-performance cutting tools and professional process support, offering more efficient and reliable machining solutions for the new energy vehicle industry and helping customers achieve highly effective machining.
