Multiple drilling machine for workpieces

摘要

Each of the first working units (7 or 8) has a first motor (26) for the movement of the working head (23) along the axis parallel to the third axis (Z). It has a gear assembly for transmission of movement from the motor to the head. The first working units are supported by the lower bearer (3), and a number of second working units are supported by the upper bearer. The second working units are movable along the longitudinal axis of the upper bearer and have at least one working head which has tools (23c) for drilling along a vertical axis of the workpiece (2).
