Three C400K Lathes: Suspended Gantry Reach and Service Scheduling

The supplier describes one gantry serving three C400K machines.

Technical application analysis. Parts within 10 kg; three C400K CNC lathes; external suspended twin-arm N-series gantry.

Reference configuration and timing

The supplier describes one gantry serving three C400K machines.
It states parts within 10 kg and approximately 12–14 s exchange.
Discharge can use a chute or conveyor.

Engineering evaluation

Verify the travel to the farthest machine, stopping position and loaded motion. Suspended support, machine maintenance access and conveyor clearance matter alongside the floor plan.

Central feeding may shorten some paths but cannot prevent all queuing. Test three simultaneous completion requests and define a priority rule, then verify safe manual recovery after a stopped cycle.

Selection conditions and evidence limits

This is distinct from the two-machine, 5 kg twin-arm M-series description. The 12–14 s range is retained without inventing an observed 13 s result.

Application questions

Can a two-machine model be extended by adding a third stop?

Only after checking structure, travel, load, control and service capacity.

What makes the farthest machine important?

Its longer service route may govern occupied time and delay the other machines.
