Abstract

PURPOSE:To avoid an electrode index rotating device from being damaged by moving a main spindle by providing a switch detecting the electrode index rotating device to be set to predetermined positions of a main spindle head and a column and a control device enabling the main spindle to move only when the electrode index rotating device is detected to be set. CONSTITUTION:A roller 11a is brought into contact with a dog 13, when an electrode index rotating device 1 comes to the predetermined position of a main spindle head 8, and with a dog 14 when the device 1 comes to the predetermined position of a column 2, and a switch 11 is placed in an on-condition. A control function, which enables a main spindle 7 to be vertically moved only when the switch 11 is placed in the on-condition, is provided. Further in a condition that the electrode index rotating device 1 is not completely housed in a storage case 4, the main spindle 7 is inhibited from its vertical movement by the control function. By the function thus controlled, the electrode index rotating device 1 can be automatically avoided from its hazard wherein the device 1 is damaged by vertically moving the main spindle 7 by mistake.
