Precision machining in Tijuana with tight tolerances

Critical parts where fit, concentricity and finish decide whether the assembly works or the line stops.

When the hundredth matters

Some parts simply have to fit. A bushing that presses too tight ruins a shaft; a cavity out of position scraps an entire lot. Precision machining is the work where the print carries geometric control, tolerances in the hundredth-of-a-millimeter range and a finish note that leaves no room for interpretation. That is where we split the process: rigid workholding, fresh tooling, controlled cutting and measurement between operations.

Reading GD&T for real

A print with geometric control is not machined like an old-school dimensioned drawing. We interpret datum frames, perpendicularity, flatness, true position and concentricity, and we set the operation order so every datum is respected from the first set-up and not lost when the part is flipped.

Control between operations

In precision work you do not measure at the end, you measure along the way. We verify critical dimensions between operations, compensate for tool wear and log the readings. If something drifts out of range it is caught on part two, not in a full box already delivered.

Finishes that are specified, not improvised

A surface finish is a functional requirement, not decoration. We tune feed, speed and tooling to reach the specified finish, and when the spec demands it we finish with grinding or polishing instead of forcing the cut.

FAQ

Frequently asked questions

What tolerance is realistic for my part?

It depends on material, size and geometry: a long aluminum plate moves more than a short stainless bushing. We review your print and tell you what we can hold repeatably before committing to a date.

Can you inspect an entire run at 100 %?

Yes, on critical characteristics. We state the impact on time and cost in the quote so you can choose between sampling and full inspection.
