# CNC Compass

> CNC sourcing answers backed by supplier records. Describe a machined part and get a structured brief, the published CNC suppliers that fit it, and the evidence behind each match. Supplier records come from public company pages and marketplace listings; a record is marked Verified only after a person has reviewed it, and each fact keeps its source.

Only reviewed (Verified) supplier records are indexable and listed in the sitemap. Treat a supplier field as a claim from the cited source, not as a guarantee of capability.
