No batch runs until the customer signs the CMM report or sends a written waiver. Night shift does not override that rule without a quality engineer on the floor.
About the shop
A family plant that still answers the phone when a dimension slips.
Northfield Precision Works is still owned by the Northfield family, but the floor runs like a contract manufacturer: documented setups, shift handovers and buyers who can reach a manufacturing engineer without a ticket queue.
Rules the floor lives by
Fixtures stay with the job
Custom fixtures are labelled with the part number and stored on racks photographed in the traveler, so a repeat order does not start from scratch six months later.
Honest capacity
If a date is tight we say so in the quote and offer partial shipments instead of missing a promise quietly. Buyers plan around truth more easily than around optimism.
Milestones buyers notice
These are the changes customers felt in lead time, paperwork or audit readiness — not vanity awards.
