03 Nov ID/OD Grinding Services in Arizona
Hard chrome plating can restore a worn component, but getting that part back to print often requires grinding at more than one stage of the job. The condition of the incoming surface affects how much material needs to be removed, while the required chrome buildup has to leave enough stock for final grinding.
Our full-service facility in Phoenix allows us to handle ID/OD grinding work alongside our plating operations. For close-tolerance components, this is ideal. Having both processes under the same roof helps us maintain control over the final dimensions and surface finish at every stage.
ID/OD Grinding Capabilities for Close-Tolerance Work
Our manual ID and OD grinding equipment accommodates parts up to 8 inches in diameter and 18 inches long. Depending on the component and specification, we can hold tolerances as tight as ±.0001 inch and achieve surface finishes down to 8 µin.
Our grinding capabilities include:
- Steel and stainless steel
- Aluminum, brass, bronze, and copper
- Carbide
- Inconel and Hastelloy
We maintain grinding wheels for conventional and unusual materials as well. Manual grinding also gives our machinists direct control over stock removal when working within an existing diameter or a specific amount of plating buildup.
Why Grinding Matters in Metal Finishing
When plating is part of the process, grinding allowances affect more than the machining operation itself. Material removed before plating changes the amount of buildup required, while the deposited coating changes the dimensions available for finish grinding.
Those numbers need to work together. On restoration work, for example, an undersized or damaged diameter may need to be ground sufficiently to clean up the surface before hard chrome is applied. The plating deposit then has to provide enough material to restore the diameter and leave the required allowance for finish grinding.
Handling these operations in-house keeps the machining requirements tied to the plating specification and final print dimensions throughout the job.
Grinding Before Chrome Plating
Pre-plate grinding is used when the existing surface or dimensions are not suitable for plating in their current condition. Worn diameters, scoring, damaged surfaces, and previous coatings can all affect how much material needs to be removed before the part enters the plating process.
Grinding before chrome plating can address issues like:
- Worn or damaged working surfaces
- Diameters requiring correction
- Existing material or coatings that are too thick
- Stock conditions that interfere with the required chrome buildup
The objective is to remove enough material to establish the required surface without creating unnecessary plating buildup. That becomes especially important on dimensional restoration work, where the pre-plate diameter determines how much chrome must be deposited before final grinding.
Finish Grinding After Hard Chrome Plating
As long as the finished component requires subsequent grinding, hard chrome can be deposited over-size. The plated surface is then ground to the specified diameter.
Our machinists work according to the plating thickness available on the component rather than applying a fixed grinding approach to every part. For close-tolerance work, that control helps preserve the required chrome deposit while bringing the component within its final dimensional specifications.
Centerless and surface grinding are also available when the geometry or print requirements call for those processes instead of ID or OD grinding.

Pre-plate grinding establishes the dimensions available for chrome buildup, while post-plate grinding brings the deposited surface to its finished specification. Our Phoenix facility handles both operations along with standalone grinding, with capacity for parts up to 8 inches in diameter and 18 inches long, tolerances as tight as ±.0001 inch, and surface finishes down to 8 µin.
