What are the hidden costs of choosing the cheapest CNC supplier for Optical lens barrel & mount?

The sticker price is not the cost

For Optical lens barrel & mount, the lowest quote often hides the real bill. As a startup / crowdfunded, you pay for scrap, rework loops, delayed launches, freight between split shops and a damaged reputation long after the PO closes. LusterControl prices transparently: material plus machine time plus finishing plus inspection plus packaging, so you can trade off tolerance, finish and volume instead of guessing.

Where the hidden cost hides

• No first-article data: incoming inspection becomes trial and error.
• Split sourcing: handoffs, freight and finger-pointing on failures.
• No traceability: a field failure becomes a manhunt, not a fix.
• Under-bought process: the part cannot hold up in the field.
