As industries continue to seek innovative ways to enhance productivity and reduce costs, FANUC's Flexible Robotic Wet Machining represents a significant leap forward in manufacturing technology. By combining high precision, durability, and adaptability, this solution offers a cost-effective and scalable alternative to traditional machining methods—especially for complex, large-scale applications.

How Wet Machining Works

At its core, Flexible Robotic Wet Machining uses FANUC’s M-800 industrial robots to perform machining tasks such as milling and drilling in a wet environment. This approach not only extends tool life and improves cut quality but also significantly reduces airborne dust and debris, creating a cleaner and safer workspace. Unlike conventional CNC machines, which are often rigid and task-specific, FANUC’s robotic solution is designed for flexibility—capable of handling varied tasks, complex angles, and large workpieces with ease.

One of the standout applications is rough machining for large components. The robot’s ability to operate in wet environments is made possible by its IP67 protection rating, which ensures resistance to dust and liquid ingress. Secondary encoders further enhance precision and durability, even under harsh conditions.

Improving Tool Life, Cut Quality, and Workplace Safety

Beyond machining, FANUC’s solution also emphasizes automation. The robotic cell can perform tool changes between spindles and even switch between a spindle and a gripper. This enables the robot to pick up a raw part, place it in a vise, machine it, and then move the finished part to a designated area—all without human intervention. This level of automation not only boosts efficiency but also reduces the need for multiple machines or manual handling.

Programming flexibility is another key advantage. With the Robot G-Code software option, users can program the robot using familiar CNC-style commands, including canned cycles and coolant control. This dual-programming capability allows seamless integration with existing CNC workflows while offering the adaptability of robotic automation.

The M-800 series robot at the heart of this system is built for performance. It boasts a payload capacity of 60 kg and a maximum reach of 2,040 mm, making it ideal for large and heavy parts. Its extensive joint motion range and high-speed capabilities are supported by a robust design that minimizes axial deflections and gear backlash, ensuring consistent precision across a wide range of tasks.

Key Benefits of Robotic Wet Machining

  • Improved tool life: Wet machining helps cool the cutting process and reduce tool wear.
  • Cleaner work environments: Coolant-assisted operation helps reduce airborne dust and debris.
  • Greater flexibility: Robots can access complex angles and large workpieces more easily than fixed machining systems.
  • Reduced manual handling: Automated part loading, machining, and unloading can improve productivity and safety.
  • Scalable automation: Robotic cells can be adapted for different parts, tools, and production requirements.

FANUC’s Flexible Robotic Wet Machining is more than just a machining solution—it’s a strategic investment in the future of smart manufacturing. By merging the strengths of robotics, CNC control, and automation, it empowers manufacturers to meet the demands of modern production with greater agility, efficiency, and confidence.
