What Is CNC Milling?
CNC milling is a precision machining process that uses rotating cutting tools to remove material from a solid workpiece and create custom parts with accurate dimensions and detailed features.
It is widely used for manufacturing plates, brackets, housings, fixtures, covers, and other parts that require flat surfaces, pockets, slots, holes, and complex contours.
At CNCTAL, our CNC milling service supports both metal and plastic materials for prototypes, low-volume production, and repeat custom orders.

CNC Milling Design Tips
Optimizing your design for CNC milling can reduce machining cost, improve production efficiency, and ensure better part quality.
Use Proper Internal Radii
Avoid sharp corners. Use standard tool radii to improve machining efficiency.
Avoid Deep Cavities
Deep pockets increase cost. Keep reasonable depth-to-width ratios.
Control Wall Thickness
Avoid very thin walls to prevent deformation during machining.
Optimize Tolerances
Only apply tight tolerances where needed to reduce machining cost.
Standardize Hole Sizes
Use standard drill sizes to simplify machining and reduce cost.
Reduce Setup Complexity
Minimize repositioning to improve accuracy and reduce machining time.
