What Accuracy Can CNC Machining Generally Achieve?

As a leading CNC Machining service provider, EMAR Technology specializes in delivering precision-engineered components. One of the most critical questions our clients – including procurement managers, engineers, and business owners – frequently ask is about the standard accuracy levels achievable through CNC processes.

Standard CNC Machining Tolerances

Typical CNC machining accuracy ranges between ±.005" to ±.0005" (±.127mm to ±.0127mm), depending on multiple factors:

• Material properties (metals vs. plastics)
• Machine tool rigidity and calibration
• Tooling quality and wear compensation
• Environmental temperature control

High-Precision CNC Capabilities

For specialized applications, our CNC precision machining services can achieve micron-level tolerances (±.0002" or 5μm) using:

• 5-axis simultaneous machining centers
• Advanced metrology equipment
• Temperature-controlled workshops
• Compensated tool path programming

Factors Affecting Machining Accuracy

At EMAR Technology, we optimize every variable to ensure consistent precision:

• Machine maintenance: Regular ball screw and guideway calibration
• Tool management: Automated tool wear monitoring systems
• Process validation: First-article inspection protocols
• Operator expertise: ASME-certified machinists
