Small batch machined parts are produced in limited quantities, where setup assumptions and design revisions can have a larger effect on the quote than in a recurring production order. The buyer should make the current lot and any expected future work distinct.
Separate current and future quantities
State the quantity requested now and list any possible repeat quantities separately. Treat forecasts as planning information, not a firm order, unless a release schedule or agreement says otherwise.
Ask how the price is built
Request clarity on material, machining, outside processes, inspection, packaging and any one-time or lot-level charges included in the quote. This helps compare small lot pricing without assuming a setup or programming fee is included.
Keep design changes controlled
Identify the current drawing revision and whether the part is still under development. If future lots may use a revised design, ask how the supplier will quote the new revision and handle any remaining material or work in process.
Define quality review for the lot
State which features will be inspected and what records are needed. If a first-piece or sample approval is part of your process, define who reviews it and whether production waits for written approval.

Confirm before release
Check that quantity, revision, included operations, inspection, packaging and delivery assumptions are visible in the quote and purchase order. Keep repeat work tied to an approved revision and a new release.
