among all machines, leading to even distribution of load
among machines to raise productivity.
● With pallet transfer method, mixed production of workpieces can be done easily.
● Workpieces are fixed onto the pallet before transferring,
thus clamp time is short and problems relating to clamping can be mitigated at each machine.
