A taxing process at the finish line
For a high-mix US metal-products manufacturer operating three shifts, manual sanding had become an operational choke point. Multiple operators worked with dual-action sanders and grinders, absorbing repetitive motion, vibration, and airborne particulate exposure throughout a physically punishing assignment.
Finish quality also depended too heavily on individual technique. Parts could be over-sanded or under-sanded, producing cosmetic variation and consuming more abrasive media than necessary. Recruiting and retaining people for the work added another constraint as demand grew.
- Reduce dependence on manual sanding across three shifts
- Relieve repetitive motion and operator fatigue
- Create more consistent surface finishes
- Accommodate varied work orders without sacrificing efficiency
A cell designed around mix and motion
The project team evaluated automation against three practical needs: lower physical strain, steadier finish quality, and better process efficiency across a varied product mix. The resulting robotic sanding cell used two stations, allowing the robot to sand at one station while an operator unloaded and reloaded the other.
Each work order carried a barcode linked to its sanding program. Scanning it prompted the cell to adjust the sanding path, while a human-machine interface let operators refine process parameters. The published record does not specify rollout phasing, operator training, or the service arrangement, so those elements cannot be attributed to this deployment.
- Evaluate the manual process, finish requirements, and sources of fatigue
- Use alternating stations to keep sanding and part handling moving
- Connect work-order barcodes to the correct sanding paths
- Retain operator control for parameter adjustments and loading
Lower cost without flattening the product mix
Sanding time fell by up to 50%, and production costs tied to sanding declined by approximately 55%. Abrasive media use dropped 50% as the programmed process reduced the variability associated with manual over-sanding and under-sanding.
Capacity increased by approximately 33%, while throughput ran up to twice as fast as manual sanding. The cell required one operator per shift, which allowed other employees to move to different work in the facility. The source also reports more consistent, repeatable finishes, better job satisfaction, and reduced turnover.
The integration lesson behind the numbers
This documented example was not deployed by Service Robot Co. and is presented as an independent analysis. Its value lies in the operating pattern: a difficult finishing task became more predictable because cell layout, work-order logic, tooling, and operator interaction were treated as a connected production system.
Service Robot Co. brings that systems view to US businesses as a full-service, OEM-neutral commercial robot integrator. We select equipment across manufacturers, arrange robot financing or robot leasing for business, perform robot deployment and integration, train the operating team, and provide service through a nationwide US engineer network. A single vendor carries the lifecycle from assessment through go-live support and an ongoing robot maintenance service plan.
