摘要:
In an electric milling machine, when a milling operation is completed, a “milling prohibition timer” is set. With the timer being set, the electric milling machine does not perform a milling operation until countdown of the timer ends and the timer is cleared even though the electric milling machine is instructed to perform the milling operation. Even when supply of electric power from an external power supply to the electric milling machine is stopped, countdown of the timer is continued by using electric power supplied from an auxiliary power supply within the electric milling machine.
