How Much Does CNC Machining Cost? (2026 Guide)

The Cost Model

• 1. Machine time: Ontario CNC milling runs $85–$120/hr, turning $85–$115/hr, mill-turn $95–$130/hr — exact rate confirmed on your quote. Every feature you add adds minutes.
• 2. Material: Weight × rate/lb × markup. Aluminum starts around $2.50/lb, mild steel $0.95/lb, 304 stainless $2.15/lb.
• 3. Setup: $30 flat — programming and fixturing. Same for one part or a thousand.
• 4. Tolerances & finish: Tighter than ±0.002" or finer than 32 Ra costs extra because it costs machine time.

Example Estimates (2026)

Part	Material	Typical Price
Simple aluminum bracket	6061, 3-axis	$60–150 each
Steel shaft with threads	12L14, turned	$40–150 each
Complex mill-turn part	One setup, multi-feature	$150–400 each
Production run, 100 pcs	Amortized setup	30–50% less per piece
Tight-tolerance die insert	Hardened, EDM + grind	$300–800 each

Design for a Cheaper Quote

• Fewer setups: Parts that machine complete in one setup beat parts that need two
• Standard stock sizes: Bar diameters and plate thicknesses you can buy off the shelf
• Generous tolerances: Only tighten what actually fits — every 0.001" of unnecessary tolerance is paid for
• Draft and radii: Avoid sharp internal corners that need special tooling
• Let the machine quote it: Our AI estimates time from your actual geometry, so you see the cost of every feature

Prototypes vs. Production

A one-off costs more per piece because setup is spread over one part. At 50–100 pieces, per-piece cost drops 30–50%. If you're prototyping, ask about our prototype-to-production path — same CAD, same shop, no re-quoting drama.
