ABSTRACT:
A drilling machine for planar face and/or end face drilling on panel-type workpieces or panel blanks which offers advantageous machining possibilities is described. Associated with the drilling machine on its operating side opposite the workpiece advancing device are a workpiece aligning table with a side stop, at either side, and a clamping device for fixing workpieces or panel blanks on the workpiece supporting table. It is, for example, thereby possible for two workpieces which belong to one piece of furniture, and in which assembly bores are to be made in mirror-image relationship, to be jointly placed on one of the workpiece aligning tables, in each case, aligned at their respective side stop and then clamped in the workpiece slider of the workpiece advancing device. The idle times of the machine can thus be reduced to a minimum.
