Can They Consistently Hold Tight Tolerances at Production Volume?

Anyone can machine a perfect prototype. The real test is whether a supplier can maintain consistency across thousands — or hundreds of thousands — of parts without dimensional drift, cosmetic defects, or quality variation.

This is where many suppliers fall apart.

A capable Swiss machining partner should be able to demonstrate:

Process repeatability
Statistical process control (SPC)
In-process inspection procedures
First article inspection capabilities
Material traceability
Long-run consistency

Repeatability matters more than promises. A supplier that produces excellent sample parts but struggles at scale creates expensive downstream problems.

Waterbury Swiss Automatics stands out because we combine decades of Swiss machining expertise with a production-focused mindset. Our operation is built around precision manufacturing at scale — not just short-run prototyping.
