Define the run before comparing suppliers
Small-batch custom CNC machining is best quoted from a defined part and quantity. Setup, material, finishing and inspection needs can affect the total scope, so a low unit price alone does not show whether two quotations are comparable.
For milling and turning options, see the CNC milling service and CNC turning service. Our low-volume production planning article covers preparation for a small run.
Make the first order repeatable
- Send the approved CAD model and drawing revision.
- State quantity, material grade, condition and finish.
- Mark dimensions that determine fit or function and identify datums.
- List inspection records or customer-specific documents that are required.
- Explain whether future batches may use another revision or quantity.
If a design detail can change, identify the allowed range and approval path. If it cannot change, mark it as an acceptance requirement. This reduces ambiguity when a repeat order is placed.
Request a complete small-batch quotation
Include the delivery destination and any secondary operations. If the project is still in prototype development, separate the prototype scope from the expected repeat build. Price, timing and process route are confirmed for the specific part and order; they are not assumed from the phrase âsmall batch.â
