FIGS. 6 to 8 show an embodiment in which the pallet is provided with drill management information. The process of boring a printed circuit board is classified into various processes such as a case where a large number of boring processes are performed with a specific drill and a case where boring processes are performed with many types of drills, depending on the type of the printed circuit board. Therefore, it may be better to store a large number of specific drills in the drill storage location, or it may be better to store multiple types of drills. If the same type of drill is stored in multiple drill storage locations where machining conditions can be set individually,
The same tool number is assigned to each drill storage location to indicate that it is the same drill.

A data table 90 is provided in the storage device 81 of the control device 80 of the printed circuit board drilling machine, and the stored drill diameter data 92, the tool number 93, the number of times of drill use 94, and the drill life for each drill storage location. A set value 95 and processing condition data 96 are set and stored. Control device 80
The calculation device 82 calculates the number of times the drill has been used 94 each time the drilling process is performed, compares it with the drill life setting value 95 each time, and determines that the drill life has been reached if the drill life setting value is exceeded. When it is determined that the service life has been reached, it is determined that if there is a drill that has been assigned the same tool number and has not reached the service life, it can be replaced.

When the drill is stored in the drill storage location according to the type of processing, the drills can be arbitrarily grouped by setting the tool number. As shown in FIG. 8, the drill storage area 1 of the pallet of the automatic drill changer

o. A drill is stored in each n in a one-to-one correspondence. A tool number is assigned to each of the stored drills for each drill having the same machining condition. As shown in FIG. 7, together with machining condition data of the drill (for example, tool rotation speed, drilling speed, etc.), a storage device in the controller 80. It is preset (stored) in 81.

When the drill replacement command in the machining program entered in the storage device or the number of times the drill has been used reaches the life set value and it is judged that the drill has reached the end of its life and drill replacement is to be performed, the machining area 139 is moved to the drill storage area 138. The tool number of the drill mounted on the spindle 9 of the moving drilling machine main body is designated.

The arithmetic unit 82 of the control unit 80 uses the tool number of the drill to be mounted on the spindle 9 and the drill storage location No. preset in the storage unit 81. 1-No. Collate with the tool number assigned to n, select the drill storage location where the drill that has not reached the end of the drill's life is stored from among the drill storage locations that match them, and replace it with the drill stored in that location.

The drill ejected by ejecting the drill to the ejecting drill case next to the drill case in which the drill having the same drill diameter that can be supplied is compared with the stored drill diameter data 113 of 1 and the life of the drill. The diameter and number of can be easily determined later.

When a new drill is supplied instead of the discharged drill, the arithmetic unit 120 updates the number of times the drill has been used in the exchange pallet data table 114, and further, via the data communication circuits 130 and 83, the exchange pallet data table. The contents of 114 are sent to the control device 80 of the printed board drilling machine. The arithmetic unit 82 of the control unit 80 updates and stores the contents of the next processing data table 97 with the sent data. Then, the pallet supplied with the new drill is sent to the pallet exchanging device as a pallet for the next processing by the transfer device.

Further, the communication of the contents of the data table is not carried out directly between the data communication circuits 83 and 130, but a storage device (not shown) and an ID unit 220 having an optical communication function are provided on the pallet to provide the optical ID system controller 21.
