Precision CNC Milling Services for Metal Parts

一、CNC Milling Dimensions Range and Tolerance Accuracy Dimensions Range Coverage CNC milling can process parts ranging from micro-sized to large components. Small parts can handle micro-holes as small as 0.5mm and narrow slots as narrow as 1mm (e.g., electronic sensor pin slots). Medium-sized parts cover conventional structural components ranging from 100-500mm (e.g., automotive gear housings). Large parts can process frame components up to 2000mm in length and weighing over 500kg (e.g., industrial racks), with 5-Axis CNC Milling ensuring overall precision for large complex parts. Tolerance Grading Three tiers based on requirements. Basic tolerance ±0.05mm (e.g., equipment housing connectors); Precision grade achieves ±0.01mm via High Precision CNC Milling (e.g., positioning holes in medical surgical instruments); Ultra-Precision grade for aerospace applications maintains ±0.003mm tolerance (e.g., satellite reflector assemblies), with every batch undergoing full inspection via coordin…
