What is CNC Machining?

CNC Machining is like a robot sculptor. You give it a digital design — it cuts, drills, and shapes metal or plastic into real parts. Fast. Precise. No mistakes

Vietnam’s CNC Machining History
Vietnam’s CNC industry began scaling around 2005-2010, first serving Japanese and Korean giants like Honda, Yamaha, Canon, Samsung, LG

Today, most CNC factories in Vietnam have 8–15 years’ experience, founded by engineers trained in foreign-owned companies

Why Vietnam?
Top-performing CNC factories in Vietnam expect 30–70% annual growth in revenue.

1. Low Labor Cost
• Avg. CNC operator salary: $350–450/month
• 50% lower than China, up to 90% lower than USA/EU
2. Low Electricity Cost: Vietnam: $0.08–0.09/kWh vs China: $0.12–0.14/kWh
3. Engineering Talents
• 40,000+ engineering graduates/year (mechanical, electrical)
• Many factory owners trained at Honda, LG, Yamaha, Canon with 10-20 years of experience
4. Strategic Location
• Trade agreements: CPTPP, RCEP, EVFTA → Reduced or 0% duty to key markets
• Major ports: Hai Phong, Da Nang, Cat Lai (handling 4.9M+ TEUs/year)
• Sea freight lead time: 22-35 days to U.S and 25–40 days to Northern Europe

Incoming Quality Control and Supplier Audits in Manufacturing

Supplier Audits
Supplier audits are formal assessments of a supplier’s quality management system, processes, and capabilities to ensure they meet the buyer’s expectations and standards.
Assess Supplier Capability: Audits verify a supplier’s ability to consistently produce high-quality materials.
Identify Potential Risks: Audits uncover potential risks and areas for improvement in the supplier’s processes.
Improve Supplier Performance: Audits provide feedback and guidance to suppliers, encouraging continuous improvement in their quality systems
Types of Supplier Audits:
First-Party Audit: Conducted by the supplier itself to assess its own compliance with its quality management system.
Second-Party Audit: Conducted by the buyer (manufacturer) to evaluate the supplier’s capabilities and compliance with the buyer’s requirements.
Third-Party Audit: Conducted by an independent certification body to assess the supplier’s compliance with industry standards or regulations.
Key Areas of Focus:
QMS: Documentation, policies, procedures, and implementation
Production Processes: Manufacturing methods, process controls, and equipment calibration.
Quality Records: Inspection data, non-conformance reports, corrective actions, and supplier performance metrics.

Incoming-Quality-Control IQC is a systematic process of inspecting and verifying incoming materials against pre-defined specifications and quality standards. It acts as a first line of defense against defects and non-conformities.
IQC help to
Prevent Defective Products: Catches potential issues early, preventing the use of substandard materials in production, thus avoiding costly rework or scrap.
Maintain Quality Consistency: Ensures that incoming materials meet the required standards, contributing to consistent product quality.
Supplier Performance Monitoring: Data provides valuable insights into supplier performance, helping identify potential problems and improve supplier relationships.
Key Activities:
Inspection: Visual inspection, dimensional measurement, material testing (chemical composition, physical properties), etc.
Documentation: Recording inspection results, deviations, and corrective actions taken.
Acceptance & Rejection: Deciding whether the material meets the acceptance criteria and authorizing its release to production or rejecting it.
