Tolerances
Tolerance-sensitive machining starts with the print, the datum strategy, and a realistic process plan built around the features that truly matter.
Overview
Tolerance requirements affect more than the final measurement step. They shape machine choice, setup sequence, workholding strategy, tooling, inspection effort, and how risk is managed during the run.
Matrix reviews tolerance-sensitive parts in the context of the drawing, quantity, material, and feature relationships rather than treating every tight number as a standalone issue.

Questions buyers ask
Do tighter tolerances affect quoting?+
Yes. Tighter tolerances can change setup strategy, inspection effort, risk, and production time, which can all affect pricing and schedule.
Should all dimensions be held the same way?+
Not necessarily. The most effective process plans distinguish between general dimensions and features that truly control fit or function.
What helps a tolerance-sensitive RFQ most?+
A clear print, defined datums, quantity, material, and notes that identify the dimensions or relationships that matter most in service.
Clarify the quality expectations before the quote gets locked in
If your job includes documentation, traceability, or feature-priority requirements, add them to the RFQ up front so the process plan and quote reflect the real scope.
