FANUC M-710iC/50 50kg Payload 6 Axis Industrial Robot CNC Machine Tending

Where This Robot Earns Its Place on a CNC Floor

High-mix shops are the hardest tending case: the part changes every few hours, the casting arrives heavier than the drawing suggests, and the machine door is only open for the time the operator takes to walk around it. A FANUC M-710iC/50 changes that arithmetic because it has enough wrist capacity to hold a double gripper and a heavy housing at the same time, and enough reach to cover the load station, two machine doors and the outfeed without a rail under the cell. The practical result is that the exchange happens inside one door opening instead of two, and the operator's walk disappears from the cycle rather than being shortened by a few seconds.

The other half of the problem is the environment. Castings arrive with coolant still on them, the fixture is blown off every cycle, and the spray lands on the wrist long before it lands anywhere else. This arm is supplied with an IP54 body and an IP67-rated wrist and J3 arm, which is the rating combination that keeps coolant and fine chips out of the wrist motors through a two-shift schedule. Where the shop runs high-pressure coolant or washes the cell down, a protection cover and dress pack are quoted at the layout stage, because retrofitting them after a motor failure costs more than the cover itself.

Reliability here is a documentary argument, not a slogan. FANUC builds this series for continuous production duty, service history and MTBF records are available through FANUC service channels on request, and the service documentation is released with the unit. Integration is documented to the same standard: the fieldbus mapping, the discrete I/O allocation and the safety schematic are handed over as a set, so a machine builder can design its gripper and write its cell program before the arm is on the water.

What Changes on the Floor

• Shorter non-cutting time. A double gripper on a wrist rated for the part plus the tooling means unload and load in one door opening, which is where most of the door window is recovered on a heavy-part cell.
• Two machines from one base, a rail when the layout grows. The reach covers two adjacent machine doors from a single position, and the same mounting flange takes a seventh-axis rail when a third machine is added, so the cell grows without a second controller or a second safety circuit.
• Machine-driven sequencing instead of timers. Door open, clamp confirm, chuck pressure and part-present signals are exchanged with the machine over the fieldbus and discrete I/O, so the arm waits on machine state and never burns an idle cycle.
• Interface openness and spare parts commonality. The controller speaks the standard industrial fieldbuses with a configurable I/O block, and the series shares motors, reducers, cables and controller boards across models, so a service stock held for one cell covers several machines instead of becoming a single-source order.

Questions Integrators Ask First

Can it work with a gantry, a vision system or force control?

Yes, with the scope fixed per cell. A gantry or seventh axis is handled as an external axis driven by the cell controller, and vision or force control runs on the cell controller or an external PC with trigger and result signals exchanged over the fieldbus or discrete I/O. Gripper design, vision recipe, force tuning and the gantry mechanics stay with the integrating party; the arm side delivers the signals, the mapping and the safety interface, and that split is written into the FAT document set.

Under what conditions is the quoted repeatability measured, and does it hold on site?

The figure is a repeatability value measured to ISO 9283 at the factory on the delivered unit, at a stabilised ambient temperature, with the arm at working temperature and the base rigidly anchored. It is not a path accuracy claim. On site it holds only with a stiff base plate and correct anchors; a flexible plate or a cold start will show more scatter than the test report. Where the process is sensitive, the FAT plan includes a warm-up routine so the number at acceptance matches the number in production.

Is the IP54 body enough in a cutting-fluid environment?

For an enclosed cell with coolant mist, splash and chip impact, yes, and the IP67 wrist and J3 arm protect the part of the arm closest to the tool. It is not a washdown rating: high-pressure jets aimed at the arm, tank cleaning or abrasive blasting need an added cover and dress pack quoted separately. If the shop washes the cell, plan the cover at the layout stage rather than after the first motor failure.

What does warranty and after-sales cover, and where does it stop?

The warranty covers the arm, controller and process package for the agreed period counted from SAT rather than from shipment, with unit-level spare parts and lead times quoted at handover. Wear items, crash damage, and failures traced to the fixture, the cell wiring or the integrator program fall outside that boundary. Because that clause decides who pays for a site visit, it is written into the co-delivery contract before the order is placed.

What is the lead time and what support is included?

Standard lead time is forty-five days for a configured unit, longer where a private label or a custom dress pack is required. Included support covers the FAT plan, the I/O map, the flange drawing and a remote review of the cell layout; on-site commissioning is quoted per project and led by the integrating party, with our engineer available for unit-level issues throughout the warranty period.
