## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for guide bushings in high-wear applications?
**A**: For high-wear applications, hardened steel guide bushings offer superior durability and resistance to deformation, while self-lubricating composites reduce maintenance by minimizing friction without external lubrication.

### Q: How do lubrication grooves in guide bushings improve performance?
**A**: Lubrication grooves in guide bushings distribute lubricant evenly across the surface, reducing friction and heat buildup, which extends component life and ensures smooth operation in hydraulic punch units.

### Q: What is the purpose of the mounting flange on guide bushings?
**A**: The mounting flange provides a secure and stable attachment point for guide bushings within machinery, ensuring precise alignment and preventing movement during operation, which is critical for maintaining accuracy in hydraulic punch units.
