A laser beam machine comprises stationary guide means, a first table movably mounted on the stationary guide means for moving between two positions, a movable guide means liftably disposed, and a second table movably mounted on the movable guide means for movement between the two positions. The tables are exchanged with each other by lifting the movable guide means to move the first and second tables between the two positions.

Laser beam machine

A first drive means is provided to an upper turret and a lower turret in such a manner as that the upper turret and lower turret can be synchronously rotated through a turret drive system, and a second drive means is provided to an upper metallic mold and a lower metallic mold in such a manner as that the upper and the lower metallic molds can be synchronously rotated within the respective turrets through a metallic mold drive system, and the metallic mold drive system is connected to the turret drive system through a differential gear mechanism. And, when the turrets are positioned, the second drive means is held stopped and the metallic molds each holding its own dividing angle are rotated within the respective turrets by the first drive means through the differential gear mechanism. The dividing of the angles for the respective metallic molds is carried out through the differential gear mechanism by the second drive means while maintaining the turrets positioned and stopped.
