Complex parts, faster turnaround, verified results.

For a repeat aerospace project, Duval’s team re-engineered OD grinding for steel stepped shafts across three part numbers using custom fixturing and a consolidated setup to complete four OD operations and four precision chamfers per piece.

The outcome: shorter lead times, lower per-unit cost, and consistent concentricity and surface finish to spec.

See how the process came together:

Two vendors tried and couldn’t keep finish or concentricity after heat treat. Duval succeeded.

For a rugged aluminum sensor housing used on environmental monitoring drones, our team engineered a custom ID/OD grinding process, stabilizing thin-wall geometry, holding ±.0003″ on the ID and .0005″ concentricity to the OD, and validating every lot with full inspection data and a Certificate of Conformance.
