We provide comprehensive OEM machining services for hollow shafts and rod bars, partnering with equipment manufacturers, automotive Tier suppliers, hydraulic system builders, and industrial machinery OEMs worldwide. Our service model is built around true engineering collaboration—from early-stage design for manufacturability (DFM) review through prototype validation to full-scale production.
Unlike standard material suppliers, we specialize in value-added precision machining of hollow cylindrical components. We transform raw tubes, hollow bars, or solid blanks into finished shafts and rods with precision bores, tight-tolerance OD profiles, keyways, cross-holes, and surface treatments ready for direct assembly into your equipment.

Core Machining Processes
Deep-Hole Drilling: Gundrilling and BTA drilling for long, straight internal bores with excellent surface finish and minimal deviation.
CNC Turning & Boring: Multi-axis CNC lathes with live tooling for simultaneous OD turning, ID boring, grooving, and threading.
Internal Honing: Precision honing to achieve exact bore size, improved cylindricity, and mirror surface finishes for hydraulic and pneumatic applications.
CNC Milling: Keyways, flats, cross-holes, radial ports, and mounting interfaces machined in a single setup.
Centerless & Cylindrical Grinding: Tight OD tolerance control and surface finish refinement for bearing journals and seal surfaces.
Induction Hardening & Surface Treatment: Localized surface hardening, nitriding, chrome plating, and ceramic coating to extend wear life.
Materials We Machine
We machine hollow shafts and rods from a wide range of ferrous and non-ferrous materials sourced to your specification:
