2. Safety Instructions

Operating a CNC machine requires adherence to strict safety protocols to prevent injury and damage to the equipment. Always read and understand these instructions before operating the machine.

• Eye Protection: Always wear safety glasses or goggles to protect your eyes from flying debris.
• Respiratory Protection: Use a dust mask or respirator, especially when working with materials that produce fine dust (e.g., wood, MDF). Ensure adequate ventilation in your workspace.
• Hand Safety: Keep hands and fingers clear of moving parts, especially the spindle and cutting tool, during operation. Do not wear loose clothing, jewelry, or gloves that could get caught in the machine.
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.
• Power Disconnection: Always disconnect power before performing any maintenance, cleaning, or assembly.
• Material Compatibility: Ensure the material you are working with is suitable for CNC milling and does not pose a fire or toxic fume hazard. The machine is not designed for carving hard metals or jade.
• Supervision: Never leave the machine unattended during operation.

4.5 Monitoring the Process

Always monitor the machine during operation. Pay attention to unusual noises, vibrations, or smoke. Be prepared to use the emergency stop button if any issues arise.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your TTC 450 CNC machine.

• Cleaning: After each use, clean the work area and machine components to remove dust and debris. Use a soft brush or compressed air. Avoid using liquids directly on electronic components.
• Lubrication: Periodically lubricate the leadscrews and linear rails according to the manufacturer's recommendations to ensure smooth movement and prevent wear.
• Component Inspection: Regularly inspect all cables, connectors, and moving parts for signs of wear or damage. Check the homing switches (X, Y, Z double limit switch + ESTOP) for proper function.
• Tool Maintenance: Keep your cutting tools sharp and clean. Dull tools can lead to poor cut quality and increased strain on the machine.
