-
Cooling and Lubrication: Implement effective cooling systems to reduce thermal stress and tool wear. Mist or cutting fluid can help maintain optimal cutting conditions.
-
Dust Control: G10 machining produces fine dust that can be hazardous. Use proper ventilation and dust collection systems to maintain a safe working environment.
-
Safety Equipment: Always wear protective gear, including goggles and respirators, to safeguard against dust and debris.
