Anodizing Options for CNC Machined Aluminum Parts:
Anodizing is one of the most common finishing options, offering strong corrosion protection and enhancing the overall appearance of metal parts. Three types of aluminum anodizing are available from Protolabs:

✱Type I-Chromic Acid: Provides a whisper-thin but still durable coating. Commonly used for welded parts and assemblies and as a primer before painting. Like all anodized surfaces, it is non-conductive.

✱Type II-Sulfuric Acid: Harder than Type I it offers an exceedingly durable finish. Usage examples include carabiner hooks, flashlight handles, motorcycle parts, and hydraulic valve bodies.

✱Type III-Hard Anodize or Hardcoat: This is the thickest and hardest anodize available and has a wide range of applications for parts and products in automotive, aerospace, heavy equipment, marine industry, general manufacturing, and military/law enforcement.

Design Consideration for Milling:
When designing parts to be CNC milled, there are several tips to keep in mind:

❋CNC milling machines are capable of precision so try to use this to your advantage
❋Avoid deep pockets which are difficult to machine
❋Sharp inside corners are often difficult so consider using a radius
❋Apply chamfers to the top edges to reduce sharpness and improve appearance.
❋Apply filters to the bottom of the pockets to reduce the possibility of stress fractures if the component is under stress.
❋Thin walls and other flimsy shapes can be difficult to machine as they may not hold up against the pressure of the cutting action.
❋Try to create shapes that do not have complex curves in more than one axis – as it may be difficult to hold during machining.
