What “tight tolerance” really costs

Aluminium is the most-machined metal in CNC for good reason — it cuts fast, finishes cleanly and covers a huge range of parts. But "how much will it cost?" rarely has a single answer. Price is driven by how the part is designed, how tight it's toleranced, how many you need, the alloy and the finish. Here's how each factor works, and the practical moves that bring cost down.

What determines aluminium CNC machining cost?

CNC machining is fundamentally about machine time — how long a part sits in the spindle, plus the setup, programming, material and finishing around it. Almost everything that affects price traces back to one of these:

• Machine time — the hours of cutting, the dominant cost on most parts.
• Setup & programming — fixed cost spread across the batch.
• Material — alloy, stock size and how much is cut away.
• Tolerance & inspection — tighter specs mean slower cuts and more checking.
• Finishing — anodising, blasting or plating add per-part cost.
