Many machine shops set a minimum order quantity or a minimum dollar value, because setup and programming cost the same whether they make one part or one thousand. Wexmar has no minimum order quantity and quotes single pieces, prototypes, and production lots on the same basis.
Buyers ask about machine shop minimum order quantity because a shop that declines small lots wastes quoting time. This page explains why minimums exist, the forms they take, and how to keep small-quantity orders affordable.
Why machine shops set a minimum order quantity
Every machined part carries fixed costs before the first chip is cut: reviewing the drawing, writing the CNC program, pulling and setting tools, building or adjusting a fixture, and proving out the first piece. At a quantity of one, that fixed cost is the entire job. Shops set up for long production runs often protect machine time by requiring a minimum lot or dollar value, so that a short job does not interrupt a profitable one.
A shop with a mix of equipment and a job-shop schedule can usually absorb small orders more easily. Short runs can be placed on a machine between larger jobs, and a lathe with live tooling or a horizontal machining center with a pallet changer can switch between parts with less downtime.
Common forms of machining minimums
| Type of minimum | How it works | Typical effect on buyers |
|---|---|---|
| Piece minimum | Shop requires a set number of parts per order | You buy more parts than you need |
| Dollar minimum | Order must meet a minimum invoice value | Small orders are priced up to the floor |
| Lot or setup charge | A one-time fee is added per release | Visible cost that shrinks per part at higher quantity |
| Material minimum | Distributor sells bar or plate in set lengths | You pay for a full bar length or plate drop |
| Outside processor minimum | Platers and heat treaters charge a lot minimum | Finishing may cost more than machining on tiny lots |
Even a shop with no minimum order cannot remove the last two. Material and outside processing minimums come from suppliers. A good estimator will show them clearly so you can decide whether to adjust quantity.
Machine shop minimum order quantity at Wexmar
Wexmar has no minimum order. We accept one-off parts, prototype lots of a few pieces, and production releases in the thousands. Our equipment supports this range: ten CNC lathes with live tooling and Y-axis, six horizontal machining centers for 3- and 4-axis milling, and four Maier Swiss machines with bar feeders for small-diameter parts up to 32 mm. Second-shift capacity and lights-out Swiss running let us carry production work while fitting short runs into the schedule.
Because turning, horizontal milling, Swiss, and inspection sit on one floor, a small order does not need to travel between suppliers. That keeps handling and freight low on the jobs where those costs matter most.
How to keep small orders affordable
- Quote quantity breaks. Ask for 1, 5, and 25 pieces. The price per part often drops sharply after the first few.
- Order spares. If you expect to need the part again, one run of ten usually costs less than two runs of five.
- Loosen non-critical tolerances. General tolerances reduce setup care and inspection time.
- Combine finishes. Group parts that share an anodize or plating spec to share the processor lot charge.
- Keep the revision stable. A new revision may require a new program and a new first article.
When a minimum order makes sense for the buyer
Sometimes ordering above your immediate need is the better choice. If a part is stable, used regularly, and inexpensive to store, a larger lot lowers unit cost and removes a reorder cycle. Blanket orders with scheduled releases let you lock in a lot-size price while taking deliveries over time. Ask the shop whether it can hold finished stock or schedule releases against one purchase order. See typical part families on our parts page.
Checklist for low-quantity RFQs
- State the quantity you need now and the likely annual usage
- Request at least three quantity breaks
- Mark which tolerances are functional
- List finishing requirements so processor minimums are visible
- Ask for the one-time charges to be shown separately
