| Mounting plates & spacers | Support structural assembly and component installation |
🛠️ Common Materials for CNC Automation Parts
| Material | Features | Typical Usage |
|---|---|---|
| Aluminum 6061 / 7075 | Lightweight, corrosion-resistant | Brackets, covers, structural parts |
| Stainless Steel 304/316 | Corrosion-resistant, hygienic | Shafts, frames, food-grade systems |
| Carbon Steel (S45C / 1045) | High strength, machinable | Gears, hubs, couplings |
| Delrin (POM) / Nylon | Low-friction, wear-resistant | Sliding guides, wear pads |
| Brass / Bronze | Good machinability, anti-friction | Bushings, valve components |
📌 Machining Requirements & Key Considerations
| Requirement | Details |
|---|---|
| Tolerance control | ±0.01 mm or better for fit-critical components |
| Surface finish | Smooth (Ra < 1.6µm where required), deburred edges |
| Batch consistency | Repeatable quality with jigs, inspection reports, and process control |
| Material traceability | 3.1 Material Certificate available on request |
| Assembly-friendly design | Optimized for fast and accurate installation |
| Protective surface treatment | Anodizing, black oxide, plating or powder coating depending on usage |
⚠️ Common CNC Issues in Automation Parts & Solutions
| Common Issue | Cause | BestPro’s Solution |
|---|---|---|
| Hole misalignment | Loose tolerance or deformation | Precision drilling + 100% key point inspection |
| Thread tolerance not matched | Poor tapping process or incorrect tools | Use of thread gauges, clear spec on drawings |
| Thin-wall deformation (Aluminum) | Aggressive machining or poor fixture | Optimized toolpath, reduced stress during machining |
| Surface damage during transport | Rubbing or vibration in packaging | Foam separation, shrink wrapping, export-grade carton + pallet |
