Surface finishing refines the look, feel, and performance of CNC plastic components. Depending on the design and application, various techniques can enhance appearance, durability, and precision. Below are the most common surface finishes available for plastic parts.
What do we have:
| Feature | Explaination |
|---|---|
| Material Selection Matters | Each plastic has different mechanical and thermal properties. Selecting the right grade early ensures machinability and performance balance. |
| Dimensional Stability and Warping | Plastics expand and contract more than metals under temperature change. Designs should allow for this movement, especially on large, flat parts or thin-walled geometries, to maintain tolerance stability after machining. |
| Optimal Wall Thickness | Thin walls can vibrate or flex under cutting forces. For most plastics, a minimum wall thickness of 1.5–2.0 mm is recommended. Reinforcing ribs or gradual transitions help prevent deformation without unnecessary bulk. |
| Corner and Fillet Design | Avoid sharp internal corners, which are difficult to machine and can become stress concentrators. Generous fillets, typically 1/3 of the cavity depth or larger, enable smoother cutting, longer tool life, and better load distribution. |
| Cavity and Pocket Depth | Deep pockets increase machining time and risk of chatter. Keeping cavity depth under four times the cavity width ensures efficient cutting while preserving surface quality and dimensional accuracy. |
| Hole and Thread Design | Limit hole depth to around 10× the diameter for stability. For threads, select standard metric or UNC sizes where possible. Threaded inserts can be used for repeated assembly without damaging plastic threads. |
| Tolerance Planning | Plastic’s thermal sensitivity and flexibility make extremely tight tolerances impractical for large areas. General tolerances of ±0.05 mm to ±0.1 mm balance cost and precision, with tighter tolerances applied only where functionally required. |
| Surface Finish Considerations | Plastics respond differently to finishing methods than metals. Polishing, vapor smoothing, or bead blasting can remove tool marks and enhance clarity or texture without affecting dimensions. |
| Assembly and Fit | Press fits and snap fits require careful allowance for material elasticity. A slight interference (typically 0.1–0.2 mm depending on the plastic type) ensures secure joining without stress cracking. |
| Thermal Management | Because plastics have low heat conductivity, excessive cutting speed or tool dwell time can cause melting or surface whitening. Using sharp tools and controlled feed rates prevents heat buildup and improves finish quality. |

Not exactly. Both are computer-controlled, but CNC machining is subtractive—it removes material—while 3D printing is additive, building parts layer by layer.
