OD Grinding Services
OD Grinding Services
Hale Performance Coatings provides precision outside diameter (OD) grinding services for round industrial components, including shafts and rolls up to 24 inches in diameter and 20 feet in length. Our outside diameter grinding capabilities help manufacturers achieve consistent surface finishes, restore critical dimensions and prepare coated components to meet application requirements.
With the addition of our newest OD grinder, Hale can accommodate large components and demanding production applications that require precise finishing. Whether OD grinding is part of an HVOF coating process or a standalone manufacturing requirement, our team can help determine the right approach for your components and production goals.
What Is OD Grinding?
OD grinding is a precision machining process used to grind the exterior surface of a round or cylindrical component. During the process, the workpiece rotates while a grinding wheel removes a controlled amount of material from its outside diameter.
OD grinding is commonly used when a component requires a precise diameter, smooth surface finish or close dimensional control. It can be performed on new production parts as well as components that have received a coating or other surface treatment.
Because the process is capable of producing consistent results across cylindrical surfaces, OD grinding is especially useful for shafts, rolls and other round components used in industrial manufacturing.
Hale Performance Coatings’ OD Grinding Capabilities
Hale’s newest OD grinding machine expands our ability to process large industrial components.
Our equipment can accommodate:
- Round parts up to 24 inches in diameter
- Components up to 20 feet in length
- Shafts
- Rolls
- Other cylindrical industrial components
- Components requiring post-coating dimensional finishing
These capabilities allow Hale Performance Coatings to support manufacturers working with large components that may exceed the capacity of smaller OD grinders.
Our team can evaluate component dimensions, coating requirements and finish specifications to determine whether our OD grinding capabilities are appropriate for your production application.
How OD Grinding Works
Outside diameter grinding uses a rotating abrasive grinding wheel to remove material from the exterior of a cylindrical workpiece. The component itself also rotates, allowing material to be removed evenly around its circumference.
The grinding process can be carefully controlled to achieve the required outside diameter and surface condition. Depending on the application, multiple grinding passes may be used to gradually bring the component to its final specification.
For coated components, OD grinding can also be used after the coating process to bring the finished surface back to the required dimensions and surface finish.
Benefits of OD Grinding
- Precise dimensional control: OD grinding allows material to be removed in a controlled manner so shafts, rolls and other round components can meet required dimensional specifications.
- Consistent surface finish: Grinding creates a uniform exterior surface that can support smooth operation and consistent component performance.
- Large-part capability: Hale’s OD grinder can accommodate components up to 24 inches in diameter and 20 feet long, supporting demanding industrial applications.
- Post-coating finishing: OD grinding can be used after HVOF thermal spray coating and other coating processes to finish a coated surface to the required dimensions.
- Production repeatability: A controlled grinding process helps manufacturers achieve consistent results across production components.
- Extended component performance: Proper surface finish and dimensional accuracy help components function as intended within demanding industrial systems.
OD Grinding and HVOF Coatings
OD grinding is an important finishing capability for many HVOF coating applications.
HVOF thermal spray adds a protective coating to a component to improve characteristics such as wear resistance, corrosion resistance and surface durability. Once the coating has been applied, the component may require grinding to achieve its specified final diameter, tolerance or surface finish.
This is particularly important with hard HVOF materials such as tungsten carbide, where specialized grinding may be necessary to finish the coated surface.
By combining coating and OD grinding capabilities, Hale Performance Coatings can help manufacturers manage multiple stages of the surface finishing process through one experienced industrial partner.
Common Applications for OD Grinding
OD grinding is well suited for round components where outside diameter, surface finish and consistent geometry are important.
Common applications include:
- Industrial shafts
- Large rolls
- Hydraulic components
- Pump shafts
- Manufacturing rolls
- Process equipment
- Machine components
- Coated cylindrical parts
- Wear-resistant surfaces
- Production equipment components
Hale’s large-component capacity makes OD grinding especially valuable for manufacturers working with long shafts and rolls used in continuous production environments.
Industries That Use OD Grinding
- Industrial Manufacturing: Shafts, rolls and cylindrical production components often require controlled diameters and consistent surface finishes.
- Steel Processing: Large rolls and related components used in material processing can require precision grinding to maintain operating performance.
- Paper and Converting: Long rolls used in continuous production equipment depend on consistent cylindrical surfaces.
- Printing and Packaging: Production rolls and rotating components require uniform finishes for reliable operation.
- Energy and Power Generation: Large shafts and rotating components may require precision surface finishing as part of manufacturing or coating programs.
- Heavy Equipment: Cylindrical components used in demanding industrial environments benefit from accurate dimensions and durable surface finishes.

OD Grinding Frequently Asked Questions
What is OD grinding?
OD grinding is a precision machining process that removes material from the outside diameter of a round or cylindrical component. It is used to achieve a specified diameter, surface finish or dimensional requirement.
What does OD stand for in grinding?
OD stands for “outside diameter.” OD grinding focuses on the exterior cylindrical surface of components such as shafts and rolls.
What is the difference between OD grinding and cylindrical grinding?
OD grinding is a type of cylindrical grinding specifically focused on the outside diameter of a round component. Cylindrical grinding can refer more broadly to grinding operations performed on cylindrical parts.
How large of a part can Hale Performance Coatings OD grind?
Hale Performance Coatings’ newest OD grinder can accommodate round components up to 24 inches in diameter and 20 feet in length.
What types of parts can be OD ground?
OD grinding is commonly used for shafts, rolls and other round industrial components that require precise outside dimensions or controlled surface finishes.
Can OD grinding be used after HVOF coating?
Yes. OD grinding can be used after an HVOF coating is applied to bring the coated component to its required final dimensions and surface finish.
Does Hale provide OD grinding for production applications?
Yes. Hale Performance Coatings works with manufacturers and OEMs requiring consistent, repeatable processing for industrial production applications.
