CNC Parts with No Minimum Order

Why some suppliers set a minimum

The economics behind a minimum start with setup. Wikipedia’s article on design for manufacturability says the cost of CNC machining is driven by time, including the set-up of the machine, NC programming and fixturing, and that the number of parts plays a critical role in amortizing that set-up and programming time into the cost of each part (source 1). No villainy involved: it’s economics.

Small work is the normal work here, so quantity one doesn’t need an exception. It just needs a quote. This page is about the ordering policy; the single part itself, the replacement, the test-rig piece, the one that will never be reordered, has its own page at one-off CNC machining.

Why one part costs more per piece

Straight talk: a quantity of one carries its entire setup, so the per-piece price is higher than the same part at twenty-five, because the same set-up and programming time is spread over fewer parts (source 1). The quote shows that plainly instead of hiding it in a “minimum charge.” CNC machining cost explains what sets the number.

Two practical tips. Ask for more than one quantity, such as 1, 25 and 100, and the quote shows each. And if the part might recur, keep the revision letter handy. Reorders at the same revision: send the last quote or PO number and it’s requoted.

What “no minimum” means in practice

No minimum quantity: one piece is an order. No minimum-charge line on the quote, and no separate setup fee: programming and setup are inside the price of the part. And no different process for small work: a person reads the print, the free design review that comes with every quote flags the expensive callouts, and every part is inspected against your print before it ships, whether the quantity is one or a hundred.

The large instant-quote platforms publish that they take a single piece too: Xometry’s FAQ lists one-offs among the work it handles (source 3), and Protolabs’ FAQ names quantities as low as one part for CNC machining (source 2). If you have been told a part is "too small to bother with," it is not too small here.

Who actually orders one part

The maintenance manager with a down machine and an obsolete part. The engineer who needs one prototype to answer one question. The builder who needs a single fixture plate. The person hunting one non-standard fastener that isn’t a stock size. And the weekend project that just needs one good billet part. All normal orders, all quoted the same way.

One now, more later

Ordering one part doesn’t commit you to more. When one becomes twenty, quantity pricing is a quote request away. A single test order is, frankly, the sensible way to try a new supplier.
