FANUC M-20iD/35 35kg Payload 1831mm Reach Hollow Wrist Heavy Handling Robot 0.03mm

Overview

The FANUC M-20iD/35 is the heavy-lift member of the M-20iD family, sharing the 1831 mm reach of the 25 kg model but carrying 35 kg at the wrist. That extra capacity is what allows a twin-chuck gripper, a heavy magnetic plate or a fixture with a built-in clamp, which is common when castings and forged parts are handled two at a time. Repeatability of 0.03 mm keeps the pickup position stable under that heavier tool load.

Wrist moments and inertia ratings are sized for heavy tools, and the hollow wrist routes gripper cables and air lines inside the arm so a rotating plate does not drag an external loom. The IP67 wrist and IP54 or IP65 body handle foundry dust, chips and coolant mist, which is where these robots usually work. The R-30iB Plus controller provides 8 in / 8 out upper-arm signals and an integrated air supply for the gripper and clamp circuits.

These robots are typically installed in foundries, forging shops and heavy machining cells for palletizing, machine tending and press transfer. Before dispatch the tool centre point is verified and the arm is dry-cycled with the customer tooling where supplied, and we can advise on gripper design, part-present sensing, guarding and safety logic for CE or ANSI compliance.

Key Specifications

Key Advantages

• 35 kg payload carries a twin-chuck gripper or a fixture with an integrated clamp.
• 1831 mm reach covers the machine load station and the pallet in one arc.
• 0.03 mm repeatability keeps the pickup point stable under a heavier tool load.
• Wrist moment and inertia ratings are sized for heavy tools and offset loads.
• The hollow wrist keeps gripper cabling and air inside the arm during rotation.
• IP67 wrist and IP54 / IP65 body suit foundry dust, chips and coolant mist.

Typical Applications

• Palletizing of castings and forged blanks
• Foundry shakeout and fettling cell handling
• Heavy machine tending with twin-chuck grippers
• Press transfer of thick blanks and formed parts
• Loading fixtures with integrated clamps
• Heavy pick and place between bins and conveyors

Frequently Asked Questions

Q: What payload does the M-20iD/35 carry?
A: The rated payload at the wrist is 35 kg, enough for a twin-chuck gripper, heavy magnetic plate or a fixture with an integrated clamp.

Q: How does it differ from the M-20iD/25?
A: Both share a 1831 mm reach, but the 35 kg model carries a heavier tool or an offset load that the 25 kg version cannot.

Q: What does 0.03 mm repeatability mean here?
A: The arm returns to the taught point within 0.03 mm, so pickup and placement positions stay stable even with a heavier tool fitted.

Q: Why is a hollow wrist important on a heavy handling robot?
A: Gripper cables and air lines run inside the arm, so a rotating plate or clamp does not drag an external loom around the wrist.

Q: What protection and power are required?
A: The wrist is IP67 and the body IP54 or IP65, and the robot runs on a 380-575 V three-phase supply at 50 or 60 Hz.

Q: Which controller is supplied?
A: The R-30iB Plus controller is standard, with 8 in / 8 out upper-arm signals and one integrated air supply.

Q: What is included with the unit?
A: Manipulator, R-30iB Plus controller, cables, documentation and a test report. Gripper, fixtures and guards are quoted separately.

Q: How is it shipped and supported?
A: It ships in an export wooden crate with shock absorbing packing, with commissioning guidance, spare parts and remote diagnostics.

When castings or forgings are handled two at a time, the 35 kg payload, 1831 mm reach and hollow wrist of the M-20iD/35 are usually specified together, because the gripper weight and the part offset are what limit the cycle. Send us the part weight, gripper drawing and cell layout and we will confirm payload margin and cycle time. In daily use the M-20iD/35 heavy handling robot runs two castings per cycle, with the 35 kg payload absorbing a twin-chuck gripper, the 1831 mm reach covering pallet and machine, and the 0.03 mm repeatability keeping both pickup points aligned; the hollow wrist keeps the gripper cabling clear through every rotation.
