ID/OD Grinding Services
Precision Cylindrical Grinding for Internal and External Diameters
At Nexus Manufacturing, we offer high-precision ID/OD Grinding Services for components that require exceptional accuracy, roundness, and surface finish.
Whether you’re dealing with hardened materials, tight tolerances, or complex geometries, our internal and external cylindrical grinding services are designed to meet your exact specifications.
We serve clients across aerospace, defence, medical, and precision tooling industries with grinding solutions that guarantee form, fit, and function—every time.
What Is ID/OD Grinding?
ID/OD grinding refers to the process of grinding the Internal Diameter (ID) and Outside Diameter (OD) of cylindrical parts. Using specialised cylindrical grinding machines, our expert team achieves:
- Ultra-tight diameter tolerances
- Superior roundness and straightness
- Mirror-like surface finishes
- Perfect alignment between internal and external diameters
This process is ideal for parts that require concentricity and precision across both bore and shaft dimensions.
Our ID/OD Grinding Capabilities
Nexus Manufacturing is equipped with precision cylindrical grinders that enable us to grind both internal and external diameters with micron-level tolerances. We can handle a wide variety of materials and part sizes, from small shafts to large sleeves and bushings.
Capabilities include:
- ID Grinding: Deep bores, blind holes, and stepped internal diameters
- OD Grinding: External cylindrical surfaces, tapered or straight
- Tolerances: Down to ±0.0001″
- Surface Finish: Ra as low as 4 μin
- Concentricity: Maintained between ID and OD features
- Part Size Range: From less than 0.25″ to over 12″ diameter
- Materials: Tool steel, stainless, Inconel, hardened alloys, ceramics
We also offer multi-step ID/OD grinding, where components require precision grinding on multiple features in a single setup—improving both accuracy and efficiency.
Common Applications
We perform ID/OD grinding for a variety of critical components used in:
- Aerospace and turbine assemblies
- Hydraulic systems and actuators
- Bearings, bushings, and sleeves
- Punches and dies
- Shafts, spindles, and rollers
- Medical implants and tooling
- High-performance gears and housings
If your parts require perfect roundness, tight fits, or high-speed rotational integrity, ID/OD grinding is the ideal process.
