Boring machine, particularly for woodworking

A woodworking boring machine for boring rows of holes and structural bores in flat workpieces such as cabinet sidewalls, cabinet doors and the like;

• comprising
• (a) a machine frame;
• (b) a workpiece holder and a boring assembly displaceable on a pair of horizontal guide rails carried by said machine frame;
• (c) a workpiece stop and a stop arrangement carried by said machine frame and having a plurality of position fingers adjustable and lockable in the direction of displacement of the boring assembly;
• (d) a supporting framework carried by said machine frame and adjustably supporting the boring assembly on the guide rails parallel to forward and rearward sides of said workpiece holder;
• (e) a first position roller mounted parallel to a longitudinal side of said workpiece holder and having a plurality of axially-extending rail guides therein in which are respectively positioned longitudinally-extending holding rails;
• (f) said position fingers being respectively positioned on respective ones of said holding rials around the circumference of said first position roller;
• and
• (g) a finger receiver displaceable on said supporting framework for cooperating with a selected one of said position fingers on said first position roller for locking the position finger in a working position with relation to the boring assembly to determine the boring position of the boring assembly along the displacement path of the boring assembly in relation to the position of the workpieces holder.
