Manufacturing capability
Precision Machining
Precision machining produces components with tightly controlled dimensions, geometric tolerances, and surface characteristics using advanced machining and inspection methods. It is widely used for aerospace, medical technology, instrumentation, automation, and industrial equipment requiring accurate mechanical interfaces.

Manufacturing overview
Precision machining encompasses manufacturing operations designed to achieve demanding dimensional and geometric requirements.
Processes may include CNC milling, turning, grinding, boring, EDM, and specialized finishing techniques.
Typical applications include precision shafts, instrument components, valve parts, tooling inserts, mechanical interfaces, and complex engineered assemblies.
Suitable materials include stainless steel, aluminum, titanium, tool steel, nickel alloys, and engineering plastics.
Critical specifications may include dimensional tolerance, position, flatness, concentricity, surface roughness, and controlled fit.
Achievable accuracy depends on component geometry, material stability, machining process, workholding, thermal conditions, and measurement capability.
For selected applications, micrometer-level tolerances may be possible, but they must be validated against actual manufacturing and inspection capability.
Buyers should provide complete technical drawings, CAD models, material grades, GD&T requirements, quantities, and inspection documentation expectations.
Quality control may include CMM inspection, first article inspection, calibrated measurement, process monitoring, and material traceability.
Metraxio supports precision machining RFQs for critical components requiring documented dimensional conformity.
Materials
A technical reference for buyers. It is not a statement that every facility offers every material.
Precision machining is applied to stainless steel, aluminum, titanium, tool steel, alloy steel and engineering plastics. The material changes both the cutting strategy and the inspection method. Name the grade. A precision callout on one feature does not mean the whole part is held to that tolerance.
Design considerations
On Metraxio, precision machining is a capability under CNC machining, not a promise of a particular machine. What matters is the drawing: which features are tight, the datum scheme, geometric controls, surface roughness and how those features will be measured. Grinding, boring or a CMM report may be part of the same project. Leave general surfaces at a commercial tolerance when that is acceptable.
What to include in the manufacturing project
Send the drawing with tolerances identified, a STEP file, the material grade, the quantity and the inspection you expect, such as a first-article report or a CMM report on named features. If a certification or a material certificate is required, say so. The project can then be assessed against facility data rather than against an undefined word like “precision”.
Buyer questions
What does precision mean here?
It means the part has features that need controlled machining and inspection. The numbers live on your drawing. Metraxio does not treat one tolerance band as the definition of precision for every material.
Is precision machining a different factory from CNC milling?
Often it is the same family of equipment, plus process control and measurement. Milling, turning, grinding and boring can all sit inside one precision requirement. List the operations the part needs.
Should every dimension be tight?
No. Tightening non-functional dimensions raises cost and can make a part unmatchable. Mark the functional fits and leave the rest to a general tolerance.
Does a public precision page mean someone can hit my tolerance?
It means you can submit the requirement. Whether a facility can hold the tolerance is assessed for that requirement, and sourcing may be needed when the current profiles do not show a fit.
