CNC milling guide

This page presents basic guidelines for cnc milling guidelines to help improve part manufacturability, enhance appearance, and reduce overall production time.

We are equipped with advanced 3-axis, 4-axis and 5-axis CNC machining centers, including Haas, Jingdiao and other high-speed CNC milling machines. We can handle a wide variety of magnesium and aluminum milling projects that require high precision and complex shape machining parts, with extremely tight tolerances and excellent surface finishes.


Most processing type Minimum Wall Thickness Minimum end mill size Minimum drill size Maximum part size Undercut Radius:Depth
Three-axis machining 1mm 1mm x 2mm x 2mm 0.5mm 1100mm x 800mm x 650mm [x,y,z] Square outline, full radius, dovetail outline Machining tolerance is +/- 0.01mm. It is recommended that all areas of the part should be thicker than 0.51mm
Four-axis machining 1mm 1mm x 2mm x 2mm 0.5mm 550mm x 350mm x 200mm [x,y,z] Square outline, full radius, dovetail outline Machining tolerance is +/- 0.01mm. It is recommended that all areas of the part should be thicker than 0.51mm
Five-axis machining 1mm 1mm x 2mm x 2mm 0.5mm 550mm x 350mm x 200mm [x,y,z] Square outline, full radius, dovetail outline Machining tolerance is +/- 0.01mm. It is recommended that all areas of the part should be thicker than 0.51mm
