8. Maintenance & Care
8.1 Operating Best Practices
-
Always use sharp tools – Dull tools cause burning and poor edge quality
-
Maintain proper chip evacuation – Use dust collection with minimum 15 m/s air velocity
-
Avoid excessive heat – Monitor for discoloration or smoke during cutting
-
Use appropriate hold-down – Ensure workpiece is securely fastened to prevent vibration
8.2 Tool Maintenance
-
Regular Cleaning: Remove resin buildup with specialized tool cleaner
-
Proper Storage: Store in original containers with desiccant packs
