## **⚙️ Common Surface Finishing Challenges & Solutions**

### **🔧 Challenge 1: Inconsistent Surface Texture**
Uneven finishes can lead to **premature wear, friction issues, or rejection in QC checks**.

✅ **Solution:**
– Use **automated abrasive blasting** for uniform texture.
– Implement **real-time monitoring systems** to detect variations.

### **🔧 Challenge 2: Corrosion & Wear Resistance**
Without proper finishing, parts degrade quickly in harsh environments.

✅ **Solution:**
– Apply **electroplating (zinc, nickel, or chrome)** for enhanced protection.
– Opt for **anodizing (for aluminum)** to improve durability.

### **🔧 Challenge 3: Burrs & Micro-Imperfections**
Leftover burrs can affect assembly and performance.

✅ **Solution:**
– **Vibratory finishing** for deburring small, complex parts.
– **Electrochemical polishing** for ultra-smooth surfaces.
