The 4 × 3 × 1 inch PEEK block in this example costs $586.38 for one, $127.41 each at 10, and $93.12 each at 100 pieces. High-value stock, heat control, workholding and slow careful passes matter alongside the setup and inspection that every quantity carries. Protect the polymer from heat and clamp marks during the run.

The PEEK example part
The part is a 4 × 3 × 1 inch block with a pocket, six holes and a general ±0.005 inch tolerance. PEEK is chosen for chemical and temperature performance in applications such as seals, insulators and wear guides; the example part does not claim a particular grade, filler or certification.
How the quantity break works
The catalog gives PEEK a $60-per-pound small-lot price and a machinability factor below aluminum. Material cost is therefore visible even on a prototype, while heat buildup, chip evacuation and clamping can add real shop time that this simple example part does not infer.
What the material or process changes
A one-piece request pays for CAM, workholding and inspection. Larger quantities spread setup, but the raw polymer and process discipline still keep the unit price above common acetal or aluminum examples. If a buyer changes to glass-filled PEEK, rerun the material and tooling assumptions.
How to turn this into a firm quote
State resin grade, filler, anneal, cleanliness, tolerance and any certificate. A good quote explains why the PEEK line is high and which assumptions the buyer can change; QuotedPart can rerun the same geometry at your rates.
Questions to settle before release
Confirm PEEK grade, filler, anneal, moisture control, cleanliness and certificate language before ordering stock. Ask whether the customer accepts tool marks and what bore stability is required at temperature. Plan chip evacuation and workholding before promising the cycle shown here. High material cost makes scrap painful, so include a first-piece inspection and a clear rework decision in the routing.
For this cost to machine peek estimate, for a firm release, have the programmer and machinist read the assumptions together. They can spot an inaccessible feature, an extra load, a tool change or an inspection step before the number reaches the buyer. Treat the computed table as a shared starting point: the shop’s measured method and the customer’s print decide which edits belong in the final route.
For PEEK, protect the blank and the first-piece inspection because scrap consumes an expensive polymer. The final release should preserve the drawing revision, stock source and inspection decision with the computed table.
Pricing engine output for the stated PEEK CNC milling example part
- • Material: PEEK; the US catalog stores its small-lot price and machinability factor.
