Small-Batch CNC Machining

The awkward middle, handled

Twenty-five parts is an awkward number in this industry: too many to pay one-off pricing without wincing, too few for suppliers whose business model starts at a thousand. The usual result is a reluctant quote with padding in it, or a “minimum order charge applies” line that makes the decision for you.

Here, small batches aren’t a favor — they’re the normal shape of the work. Runs of 1 to 100 get quoted promptly, priced honestly, and treated like the real orders they are.

How small-batch pricing actually works

The economics are worth understanding because they work in your favor: programming and setup are fixed costs. Piece one carries all of it; piece twenty-five carries a twenty-fifth. That’s why the per-piece price falls fast over the first few quantity breaks — it’s amortization, not a discount trick.

The practical move: ask for two or three quantities on the same quote — 10, 25, 50 — and look at the curve before you decide. The quote shows the math plainly; there’s nothing clever hiding in it.

Reorders that match the first batch

A small batch is often the first of several. The print is the contract: reorder against the same revision and the parts are made and inspected against the same dimensions as last time. Put the revision letter on your PO and batch two matches batch one — and if you’ve revised the print in between, say so and the quote tracks the new rev.

A whole assembly in one order

Mixed orders are welcome: a ZIP with eight different parts quotes as one job and ships together, or in stages if your build schedule wants it that way. For machine builders putting together a full equipment build, that’s usually the saner way to buy than eight separate purchase orders.
