When your part requires absolute precision, Duval Precision Grinding delivers. With more than 75 years of expertise, our cylindrical grinding services — including Outside Diameter (OD) and Internal Diameter (ID) grinding — consistently achieve the tight tolerances, fine finishes, and repeatable accuracy demanded by aerospace, defense, and capital equipment for advanced manufacturing.
From prototypes to high-volume production, our grinding services provide the accuracy and finish quality your applications demand.
Precision = Performance
Cylindrical grinding ensures a precise fit and reliable performance, often serving as the final stage before a part is assembled and put into service. At Duval, our grinders and process engineers apply decades of expertise in a climate-controlled environment to ensure every detail meets your exact specifications:
- Tolerances: to ±0.0001 in
- Surface finish: as fine as 4 micro
- Geometry control: concentricity and cylindricity held within 0.0001 in
Backed by decades of hands-on experience and engineering expertise, these capabilities form the foundation of our reputation as a trusted name in precision grinding.
OD Grinding Services
