CNC Machining Prices — How Quotes Are Built (2026)

The first machined part quote is always a shock: '$180 for this little bracket?' Here's what's inside that number — and why part #10 costs $35.

Quick answer: CNC price per part = cycle time × shop rate + setup ÷ batch + stock + tooling. US rates: 3-axis $40–75/h, lathe $50–90, 5-axis $90–150. A 22-minute part with 90-min setup at $60/h, $8 stock: $33/part at 50 pieces — $102 at 1. Setup is the whole story of small-batch pricing.

Shop rates (US, 2026)

  • 3-axis milling: $40–75/hour
  • CNC turning: $50–90/hour
  • 5-axis and swiss: $90–150/hour
  • Rates bundle the machine, operator, coolant, inspection and overhead — quotes show hours, not the rate.

Setup — the small-batch tax

Fixturing, tool selection, program proofing and first-article inspection run 1–3 hours before part #1. At $60/hour that's $60–180 spread across the batch: $1.80/part at 100, $18/part at 10, the whole quote at 1. This is why 10 identical parts cost barely more than 1 — and why designers who batch their hardware orders save 3–5× per part.

Stock — the second surprise

  • Bar and plate run $2–10/lb by alloy: 6061 aluminum $3–5, 303 stainless $4–6, titanium multiples.
  • Shops price the closest stock size, not the finished weight — remnant pricing is higher per pound.
  • Machining away 70% of a billet is paying to make chips; design near stock sizes when volume matters.

Reading a quote line by line

A good quote shows: setup hours, cycle hours, material, finish (anodize ~$50–150 lot charge, plating similar), and quantity breaks. Push back with math, not vibes: 'can we run this at 50 pieces to amortize setup?' is a question every shop respects — 'can you do better on price?' without a lever is not.

Frequently Asked Questions

How much does CNC machining cost?
Per hour: $40–150 by machine class (US 2026). Per part: $10–100 covers most simple brackets and housings at modest batches; prototypes with setup absorbed run $150–500+. Material-heavy or 5-axis work climbs from there.
Why do machinists charge so much for one part?
Setup is the product at quantity 1: the same programming, fixturing and proving regardless of parts. Batch 10 and the per-part setup drops 90%. One-part pricing isn't greed — it's arithmetic the customer can verify.
How can I reduce my CNC costs?
Batch parts, design to stock sizes, loosen tolerances to ±0.005" where possible, avoid deep pockets and thin walls, and let the shop pick the finish. Each move attacks a specific line of the quote.
Should I get quotes from multiple shops?
Yes — 3 quotes is the standard. Spread of 2× on identical RFQs is normal (different machines, backlogs, overhead). The cheapest quote with no line items is a gamble; the mid quote with setup/cycle/material shown is information.
When does injection molding beat CNC?
The classic break-even: when unit volume × (CNC cost − molding cost) > mold cost. At $33 CNC vs $0.28 molded, a $15k mold breaks even around 500 pieces. The molding calculator runs both sides of that comparison.
