Quality Assurance at HS CNC
Precision is in every detail. Our CNC machining quality control system ensures every CNC machined part meets your specifications, from raw material inspection to final delivery.
Our Quality Commitment
ISO Compliant System
We operate under ISO 9001-aligned quality management systems, ensuring consistent quality across all orders.
100% In-Process Inspection
Every part goes through multi-stage inspection during production to catch deviations early.
Material Traceability
Full traceability of all raw materials, with certificates provided for every batch.
Precision Metrology
Advanced inspection equipment ensures tight tolerances and dimensional accuracy down to ±0.001mm.
Our CNC Machining Quality Control Workflow
Our complete CNC machining quality control covers every production stage. We start with raw material verification to confirm material certificates and material traceability. After machining, our inspectors carry out dimensional checks with calipers, micrometers and CMM machines to verify tolerances.
Visual and geometric inspection is the final critical step. We use microscopes, magnifiers and concentricity gauges to check surface finish, micro burrs and GD&T geometric tolerances, especially for vacuum and semiconductor components. All inspection records are saved and inspection reports can be provided before shipment.
Our team strictly follows ISO 9001 requirements. Whether you need prototypes or batch production, our CNC machining quality control process guarantees consistent part quality and reduces defect rates.
We understand that precision CNC machined parts must perform reliably in demanding environments. Every component goes through documented inspection steps, and we provide first-article inspection reports (FAI) and dimensional inspection reports for batch orders. Our goal is to help customers reduce rework, avoid assembly issues and shorten their production cycle.
Whether you are sourcing stainless steel, oxygen-free copper, aluminum or engineering plastics, our quality inspection capabilities are designed to meet the strict requirements of semiconductor, aerospace, medical and automation industries.
1. Raw Material Receiving & Inspection
Verify material certificates, chemical composition, and physical properties.
2. First Article Inspection (FAI)
Full dimensional inspection of the first produced part to confirm design compliance.
3. In-Process Quality Checks
Regular dimensional checks during machining to maintain tolerances.
4. Final Inspection & Testing
Comprehensive inspection using CMM, micrometers, and optical comparators.
5. Cleaning & Finishing Verification
Confirm surface treatment, cleanliness, and cosmetic requirements.
6. Packaging & Shipment
Anti-corrosion packaging with full inspection reports included.
Inspection Equipment
Roughness Tester (Mitutoyo SJ-210)
Our portable Mitutoyo SJ-210 surface roughness tester provides fast, accurate measurements of surface finish (Ra, Rz, and more) on machined parts. It supports multi-angle measurement and is widely used for quality control of automotive components, molds, and precision mechanical parts.
Coordinate Measuring Machine (CMM) – SEREIN Croma Series
Our SEREIN Croma CMM (part of Hexagon Group) delivers high-precision 3D dimensional inspection for complex machined parts. Equipped with advanced sensor technology, it ensures full geometric accuracy verification for automotive, mold, and aerospace components.
Optical Comparator / Visual Inspection System (TASO 2.5D)
Our TASO 2.5D optical measuring system enables non-contact inspection of small and complex features, including dimensions, angles, and contours. It is ideal for high-volume quality checks of precision hardware, electronic components, and fine stamping parts.
Certifications & Standards
Certified to ISO 9001 standards, we implement a strict quality management system across all processes — from raw material receiving to final inspection and delivery.
