Nylon CNC machining requires specific techniques to achieve optimal results. As a semi-crystalline thermoplastic, nylon exhibits unique machining characteristics that differ from metals and even other plastics.
Nylon Machining Characteristics
Nylon (PA6, PA66, PA12) offers excellent machinability when proper techniques are applied:
- Low cutting forces — requires less power than metals
- Good chip formation — produces continuous chips that clear easily
- Heat sensitivity — can soften if excessive heat builds up
- Moisture absorption — dimensional changes possible before/after machining
Recommended Machining Parameters
| Operation | Speed (m/min) | Feed (mm/rev) | Depth (mm) |
|---|---|---|---|
| Turning | 200-400 | 0.1-0.3 | 0.5-3.0 |
| Milling | 150-300 | 0.05-0.2/tooth | 0.5-2.0 |
| Drilling | 50-100 | 0.1-0.3 | Through hole |
Critical Considerations
Moisture Management
Nylon absorbs moisture from the atmosphere, causing dimensional changes. Best practices:
- Dry stock before machining (80°C for 4-6 hours)
- Machine in controlled humidity environment
- Store machined parts in sealed bags with desiccant
Tool Selection
- Sharp tools essential — dull tools generate heat and poor finish
- Positive rake angles — 5-15° for clean cutting
- Polished flutes — prevent chip welding
- Carbide tools — standard HSS works, carbide lasts longer
Achievable Tolerances
- Standard: ±0.1mm
- Precision: ±0.05mm with proper technique
- High precision: ±0.025mm possible under controlled conditions
