Surface Treatment for CNC Machined Parts

Surface treatment for CNC machined parts enhances durability, performance, and aesthetics by modifying the material’s surface. Standard techniques include anodizing, plating, coating, polishing, and shot peening. These treatments improve corrosion resistance, wear resistance, and surface hardness. For example, anodizing aluminum increases its resistance to corrosion, while shot peening improves fatigue resistance. Surface treatments are crucial for industries like aerospace, automotive, and medical devices, where component longevity and reliability are critical under harsh operational conditions.

CNC Machining Design Suggestions

CNC machining design suggestions focus on optimizing parts for efficient production. Key points include using rounded corners, maintaining reasonable hole depth-to-diameter ratios, minimizing tight tolerances, ensuring tool access, simplifying shapes, and considering part weight and size. These strategies reduce machining time, cost, and complexity.

Items

Suggestions

Radii and Fillets

Use rounded corners (radii) instead of sharp internal corners. Sharp corners can cause tool wear and weak points in the part. External corners should also be rounded or chamfered to avoid damage.

Hole Design

For drilled holes, keep the depth no more than 5 times the hole diameter. For tapped holes, the depth should be 3 times the diameter for small sizes (e.g., 1.5-5 mm) and 4-6 times the diameter for larger sizes.

Thread Design

Ensure tapped hole diameters are slightly smaller than the thread size (e.g., for M6, use a 5 mm hole diameter). Limit thread depth to 1.5-2 times the thread diameter.

Undercuts and Complex Shapes

Avoid undercuts or difficult-to-reach areas that require special tools. Use simple shapes or profiles for easier machining (e.g., avoid square or sharp-angle pockets).

Tolerances

Avoid overly tight tolerances unless absolutely necessary. General tolerances (e.g., ±0.1 mm) are often sufficient for most parts.

Tool Access and Clearance

Design parts with enough space around features for tools to reach them. Avoid narrow or deep features that are hard to access. Ensure adequate clearance for tool paths to prevent interference.

Wall Thickness

Keep wall thickness consistent to avoid difficulties in machining and potential warping. Avoid very thin sections, as they can be hard to machine accurately.

Chamfers and Bevels

Add chamfers (typically 0.5-1 mm) to edges to prevent sharp burrs and make part handling easier.

Surface Finish

Specify rougher finishes (e.g., Ra 3.2) when possible to reduce machining time and cost. Finer finishes require more time and expensive tools.

Assembly and Machining Efficiency

Design parts that are easy to assemble by incorporating self-locating holes or mounting points. Minimize the number of tool changes and fixture adjustments to reduce machining time.

Weight and Size

Keep part weight and size in check to avoid needing special equipment or setups for larger or heavier parts.
