Manual grinding is flexible but unstable
Operators can handle many shapes manually, but quality depends on skill and fatigue. For repeated parts, this creates variation and hidden rework.
Automatic sanding improves repeatability
A feed-through sanding machine controls abrasive contact and speed more consistently. This is useful for factories processing similar parts every day.
When to invest
If manual grinding becomes a production bottleneck or customer complaints are caused by inconsistent edges, automatic sanding should be evaluated.
