Custom Aluminum CNC Bewerking Design Guidelines
Ontwerp voor maakbaarheid (DFM)
The following are guidelines to optimize your aluminum parts for CNC milling, reduce the costs, and improve lead times.
Tolerance Guidelines
Tight tolerances should only be specified where functional necessity dictates. Tighter tolerances cause machining time and cost to rise exponentially.
Wall Thickness
Thin walls may vibrate or deflect during machining. The thickness should, therefore, be maintained enough to provide dimensional stability.
Internal Corners
The internal corners must have a radius equal to or greater than the largest tool radius they will encounter. Smaller radii lead to lesser tool sizes and longer machining times.
Hole Depth
Standard drills function best in hole depths around 4x the diameter. Specialized tools and peck drilling cycles are required for depths >4x diameter.
Thread Design
Threads of aluminum are not particularly strong, so in the case of frequent assembly and/or higher loads, one might choose to go for threaded inserts (Helicoils).
Surface Finishing for CNC Machined Aluminum
Choose from our complete selection of surface treatments to enhance the aesthetics of your aluminum parts, give them better protection against corrosion, and make them more functional.
THE MOST USED
Type II Anodizing
The basic anodizing process plus the possibility to choose among different colors for decor. With the stacking of the layers being thinner, it has quite good protection against corrosion.
- More than one shade offered
- 0.0002" to 0.001" thickness
- MIL-A-8625 Type II
HIGH WEAR
Type III Hard Anodizing
A thick and hard oxide layer is created to resist wear and, in some cases, even surpass the wear resistance of the application, thus, making it fully suitable for demanding conditions.
- HRC 60-70 hardness
- 0.001" to 0.003" thickness
- MIL-A-8625 Type III
MATTE FINISH
Bead Blasting
A uniform matte finish that covers up the marks left by machining. It is widely used as the pre-treatment process prior to anodizing.
- Typical Ra 1.6-3.2 µm
- Cost-efficient
- Satin like appearance
THICK COATING
Powder Coating
Long-lasting polymer coating with a wide range of colors. Outdoor equipment requiring thick protection can be painted with this because it is intended for such.
- 0.002" to 0.006" thickness
- RAL colors available
- UV resistant
Chromate Conversion (Alodine)
A lightweight coating that still lets electricity pass through. Moreover, it can act as an excellent primer for the next layers of paint because of its great adhesion.
- Electricity passage still possible
- MIL-DTL-5541 compliant
- Golden or transparent choices
WEAR + CORROSION
Electroless Nickel Plating
A layer of nickel that is applied uniformly and has very good resistance against both wear and corrosion. It is self-leveling so that the thickness throughout is always consistent.
- Uniform thickness
- 50 HRC hardness
- Chemical resistant

CNC machined aluminum
Aluminum is a relatively easy metal to machine which makes it great for CNC-bewerking. Aluminum has useful properties for machining such as being lightweight, malleable, tractable and overall good durability. It being so light and easy to work with means that it can be used for a wide variety of applications. CNC machined Aluminum parts begin as a raw piece of metal which is cut down bit by bit to create a desired shape or object. This process is done most accurately with a CNC machine which can produce almost any three dimensional object designed via CAD software.
