ID & OD Grinding
Precision cylindrical grinding for true bores, round shafts, and flawless fits.
Legacy Welding & Fabrication provides internal (ID) and external (OD) grinding for accurate diameters, superior surface finish, and controlled geometry. From hardened shafts and bushings to precision sleeves and bearing fits, our process delivers tight tolerances and repeatable results that assemble smoothly and run true in the field.
Process Highlights
- ID and OD cylindrical grinding—plunge and traverse
- Shoulders, steps, reliefs, tapers, and face cleanup
- Pre-grind and finish-grind workflows for heat-treated parts
- In-process gauging for stable, repeatable dimensions
Quality You Can Trust
We set up on centers and precision fixtures, balance wheels, and verify thermal stability for every run. Critical features are checked at setup, monitored in-process, and confirmed at final inspection. Expect true bores, consistent diameters, clean surface finishes, and dependable fits that press, slide, or run on bearings exactly as designed.Materials & Capabilities
We grind a wide range of materials—from carbon and alloy steels to hardened tool steel and stainless—maintaining roundness and size control on both small bores and long shafts.- Materials: Carbon & Alloy Steels, Stainless (300/400), Tool Steel, Nitrided/Carburized steels, Cast Iron, Bronze
- Geometry: Roundness, concentricity, taper, and straightness control
- Tolerances: Typical ±0.0002" on diameter; tighter by request with documented inspection
- Finish: Surface finishes to 16 µin Ra or better depending on material
- Post-process: Light polish/lap; coordination of plating/passivation as needed
