Quality Assurance for Consistent, Reliable CNC Parts
Quality assurance is not just about inspection. It is about controlling variation before it affects your parts.
At 6 CNC, we apply a structured quality assurance process across every stage of production. This helps you avoid rework, reduce delays, and ensure that parts perform as expected.
- surface finish capability: up to Ra 1.66.
- First article inspection
- CMM measurement for complex geometries
Inspection Equipment and Measurement Capability
We use precision inspection equipment to verify critical dimensions and ensure accuracy.
Our inspection capability includes:
- CMM measurement for complex geometries
- Dimensional inspection for critical features
- Surface roughness measurement
6 CNC tolerance capability: up to ±0.002 mm
These tools allow us to verify both simple and complex features with consistency.
In-Process Quality Control
Quality is monitored during machining, not only after production.
We perform inspections at key stages, including:
- First article inspection
- In-process checks
- Final inspection
This approach allows us to detect deviations early and correct them before they affect the entire batch.
Why Choose 6CNC?
At 6 CNC, we apply quality assurance processes throughout the entire manufacturing workflow to reduce risk and deliver reliable results.
Surface Finish and Functional Verification
Surface quality directly affects part performance. We verify surface finish and critical functional features to ensure: Proper sealing performance Smooth contact surfaces Reduced wear and friction 6 CNC surface finish capability: up to Ra 1.6
Material Control and Traceability
Material consistency is critical for part performance. We verify incoming materials and maintain traceability throughout production. This ensures that each part is produced using the correct material and meets your specifications.
Consistency Across Production Batches
Repeatability is essential for production machining. We maintain consistent machining parameters, tooling setups, and inspection standards across all orders. This ensures that repeat production matches your original specifications.
Design Review and Risk Prevention
Many quality issues start at the design stage. We review your design before production to identify risks such as: Tight tolerances Complex geometries Difficult-to-machine features Addressing these issues early helps reduce cost and avoid delays.
Certified Quality Management System
We operate under internationally recognized quality and environmental standards to ensure consistent and reliable manufacturing.
Our certifications include:
- ISO 9001 – Quality management system for consistent production and process control
- ISO 13485 – Quality requirements for medical device manufacturing
- ISO 14001 – Environmental management and responsible production practices
These certifications confirm that our processes are controlled, documented, and continuously improved.
For you, this means lower risk, better traceability, and more reliable part performance.

FAQ About Medical Precision Machining
How do you ensure CNC machining quality?
We ensure quality through process control, in-process inspection, and final verification.
This reduces variation and ensures consistent results.
What inspection methods do you use?
We use Zeiss CMM inspection and dimensional measurement to verify critical features and tolerances.
Can you guarantee tight tolerances?
6 CNC machining capability: tolerance up to ±0.002 mm.
Actual tolerance depends on material and part design.
How do you maintain consistency across batches?
We use standardized machining setups, tooling strategies, and inspection processes.
This ensures repeatability across all production runs.
What’s the difference between general CNC machining and high precision medical machining?
High precision medical machining usually requires tighter process control, more inspection discipline, clearer documentation, and better consistency across batches. The quality expectation is higher because the parts often support safety-critical or performance-sensitive applications.
Do you provide material verification?
Yes. We verify material specifications and maintain traceability throughout production.
