How do you maintain tight tolerances when a“simple” parts contains a complex holes?

What looks simple is often where tolerance control becomes most critical.
At this level, it's no longer about individual features—it's about the overall geometric consistency of the part.

For this type of component, we focus on:
Datum-based setup to keep all features aligned to a stable reference
Controlled machining stages (rough → finish) to manage stress and deformation
Single-setup finishing for key hole patterns to reduce positional variation
Custom fixturing to ensure stability and repeatability
In multi-hole parts, issues rarely come from one feature—they come from small deviations accumulating across the process.

You're not just machining holes—you're controlling a tolerance chain that defines final assembly accuracy.
