🔧 CNC Machining Standards & Quality Control

Let me tell you, quality control in CNC machining is NO JOKE! These factories follow strict standards to ensure
every part is perfect. Here’s what you need to know:

Tolerance Standards

  • ISO 2768 – General tolerances for linear and angular dimensions
  • IT Grades (IT01 to IT18) – Precision levels from ultra-fine to coarse
  • ASME Y14.5 – Geometric Dimensioning and Tolerancing (GD&T)
  • GB/T 34880.2-2025 – 5-axis machining center accuracy standards

Precision Levels

  • Ultra-precision: ±0.005mm (0.0002 inches)
  • High precision: ±0.01mm (0.0004 inches)
  • Standard precision: ±0.02mm (0.0008 inches)
  • Coarse precision: ±0.05mm (0.002 inches)

Surface Finish

  • Ra 0.1μm – Mirror finish for critical surfaces
  • Ra 0.4μm – Fine finish for mating surfaces
  • Ra 1.6μm – Standard finish for most applications
  • Ra 6.3μm – Rough finish for non-critical surfaces

🤔 How to Choose the Right CNC Factory for You

Choosing a CNC factory can be tricky, but don’t worry – I’ve got your back! Here’s what you need to look for:
