摘要 |
The drilling machine comprises a pair of cross slides formed of two parallelepiped blocks of granite connected as a T above a horizontally stationary board carrying table. The transverse block carries two operating heads and, by means of pneumostatic bearings, guides their movement along the X-axis. The other block is guided by the machine frame by means of other pneumostatic bearings. Each head carries a spindle operable to lock and unlock the tool to permit automatic tool replacement from a corresponding tool magazine with provision for checking the integrity of the engaged tool. One of the heads can be disengaged from the X-axis servomotor and connected to the other one at a predetermined distance. Two series of equal printed circuit supports can be drilled simultaneously by using a single package of boards to be cut after the drilling or the etching. Tool changing and tool integrity checking operations can be effected simultaneously for the two operating heads. |
