Pricing for CNC cutting (like laser or milling-based) in our custom machining services is fully customized based on your unique needs – no fixed rates, just transparent breakdowns! Key stages influencing cost include:
Material & Thickness: Base cost varies by material type (e.g., aluminum vs. titanium) and thickness.
Complexity & Size: Simple 2D profiles charge less than intricate designs with tight tolerances (±0.005mm); larger worktables (up to 1500x3000mm) add setup time on V6 mills (800x500mm range).
Volume & Batch Size: Prototypes (1-10 pcs) have higher per-unit rates due to setup; scaling to 100+ pcs reduces costs by 40% through our 40+ CNC mills’ efficiency – no MOQ required.
Surface Finishes & Add-Ons: Basic delivery is standard; extras like anodizing or grinding (Ra 0.4μm) add 10-15% for enhanced durability, integrated post-machining.
