Fanuc Robotics has launched a large 6kg payload version (M-3iA) of its lightweight 0.5kg parallel link design robot (M-1iA).

Available in four- or six-axis configurations, the design provides a compact handling solution for machine or system integration.

Aimed at assembly and packing operations, the parallel link structure allows the compact M-3iA to be located safely in confined areas.

Its cylindrical work envelope, measuring 0.5Mtr in depth by 1.350Mtr in diameter, is concentric to the robot mounting base, making it straightforward to position and guard relative to peripheral equipment.

Available in a four-axis configuration as well as a six-axis version, all joint motors are positioned well away from the wrist, avoiding being exposed to high acceleration and, depending on the application, aggressive materials.

All joints and mated components are completely enclosed and sealed to an IP67 rating; the wrist is suitable for working in a dust- or oil-mist environment.

As a result of the importance of this high-speed configuration for picking and packaging applications, Fanuc Robotics has produced a food and pharmaceutical version.

The Fanuc Robotics M-3iA food robot has a white epoxy finish for harsh material protection, which also allows the arm to be disinfected with acid and alkaline fluids.

Food-grade grease completes the specification.

With wrist speeds of 4,000 degrees per second for the four-axis and 2,000 degrees per second for the six-axes version, the M-3iA has a repeatability of 0.1mm.

The four-axis model (M-3iA/6S) has a hollow wrist for routing hoses through the centre of the gripper, reducing interference, hose breakages and downtime while permitting very fast workpiece rotations.

Applications requiring more complex positioning are suitable for the six-axis M-3iA/6A, with its ability to pick up components, assemble them at an angle and rotate them, effectively replicating a human operator but at far greater speed, with high repeatability over an indefinite sustained period.

The Fanuc Robotics M-3iA is controlled by the R-30iA controller, with integrated functions including IRVision, Robot Link and Collision protection.

All that the robot requires to benefit from IRVision is a camera and a cable to connect it to the controller; a housing is provided in the robot body to position a camera above the wrist of the M-3iA.

FANUC UK provides industrial automation solutions ranging from the supply of CNC controllers, robots, drilling machines, EDM and injection moulding machines through to the complete integration of factory automation systems.

Providing a single customer support portal for its three core businesses, FANUC comprises FA — CNC controllers, motors and drives; robotics — industrial robots and systems; robomachines — EDM, injection moulding and drilling machines.


FANUC’s FA business manufactures CNC controls, drive systems and laser systems. With a 65 per cent market share in the global CNC control sector, FANUC is the market leader. FANUC CNC is the controller of choice for the world’s leading machine tool manufacturers; continuously developing functionality sees FANUC CNC control being used in a wide range of applications — combining powerful control and high precision with unparalleled reliability.

FANUC servo drives and motors are well proven — aimed at the machine builder, they offer the widest range of high-performance compact designs.  The high availability and ease of maintenance together with world-class, energy-efficient designs make them the motors of choice for thousands of OEMs around the world.


FANUC’s robotics business manufactures the widest range of robots in the world for applications from micro-electronics assembly to the forging of precision aerofoils for jet engines — in industries as diverse as pharmaceutical and potato processing — and with maximum payloads from 1kg to 1,350kg. More than 280,000 FANUC robots are operating worldwide, with production currently geared to meet demands of 5,000 per month. FANUC robots are truly ‘out-of-the-box’ automation designed to be totally flexible and, with application-specific options, straightforward to integrate.


FANUC’s robomachine business manufactures Robodrill machining centres, Robocut EDM machines and Roboshot electric injection-moulding machines. Using FANUC components throughout, the robomachine business builds on the advanced technology, reliability, energy efficiency and innovation of its own controllers, drives and motors. With a focus on energy efficiency and high reliability, the robomachine business developed the first all-electric injection-moulding machines — Roboshot — changing the mould shop into a much cleaner and quieter environment.
