Custom Aluminum CNC Machining Design Guidelines
Design for Manufacturability (DFM)
Optimize your aluminum parts for CNC milling to reduce costs and improve lead times.
Tolerance Guidelines
Tight tolerances increase machining time and costs. Specify precision only where functional necessity dictates.
Wall Thickness
Thin walls may vibrate or deflect. Maintain adequate thickness for better dimensional stability.
Internal Corners
Corners must have a radius equal to or greater than the tool radius to avoid specialized small tools.
Hole Depth
Standard drills work best at depths up to 4x the diameter. Deeper holes require specialized peck cycles.
Thread Design
For frequent assembly or high loads in aluminum, consider using Helicoils (threaded inserts) for strength.
Surface Finishing for CNC Machined Aluminum Parts
Whether your project requires improved corrosion resistance, wear protection, conductivity, or cosmetic enhancement, our aluminum CNC machining service provides finishing solutions tailored to your application requirements.
