In precision machining, tolerance defines how close a manufactured part is to its intended design. For industries like aerospace, medical, and electronics, even the smallest deviation can cause failures. That’s why Swiss CNC machining is trusted to achieve tolerances as tight as ±0.005 mm—a level of precision that separates reliable parts from risky ones.
What Does ±0.005 mm Mean?
A tolerance of ±0.005 mm means that the actual part dimension can only vary by five microns (about 1/10 the thickness of a human hair). At this scale, every detail matters.
Why Tight Tolerances Are Critical
-
Aerospace – ensures components fit and function under extreme stress and vibration.
-
Medical Devices – guarantees reliability in surgical instruments and diagnostic tools.
-
Telecommunications – maintains signal integrity in high-frequency connectors.
-
Automotive – ensures safety and consistency in sensors and control systems.
Without this precision, performance, safety, and reliability are at risk.
How Swiss CNC Achieves It
Swiss CNC lathes excel in micro-precision because of:
-
Guide Bushing Stability – supports slender parts during turning.
-
Multi-Axis Control – allows complex geometries in a single setup.
-
High-Resolution Tooling – ensures repeatability across millions of cycles.
-
Burr-Free Finishes – essential for electrical and mechanical reliability.
VF Decolletage Precision Standards
At VF Decolletage, we operate Star, Tsugami, and Cincom Swiss CNC machines capable of achieving ±0.005 mm tolerances. Backed by ISO 9001:2015 certification and advanced inspection tools like Keyence vision systems and Mitutoyo gauges, we ensure that every connector pin, test probe, and screw machine part meets the strictest requirements.
Conclusion
±0.005 mm tolerances may sound small, but they are critical for industries where failure is not an option. By combining Swiss CNC technology with rigorous quality control, VF Decolletage delivers parts that set the standard for precision and reliability.
