ABSTRACT:
The invention relates to a boring machine, particularly for woodworking, for boring rows of holes and structural bores in plate-shaped workpieces such as cabinet sidewalls, cabinet doors, etc., with a machine frame having a workpiece holder and an adjustable multi-spindle boring assembly arranged over the workpiece holder, a fixed, longitudinally oriented workpiece stop being mounted on the back of the workpiece holder, and which has a stop fixture consisting of stop rails aligned parallel to and projecting laterally at the longitudinal sides of the workpiece holder and whereat adjustable and lockable stop receivers can be introduced into the stop rails, the stop receivers receiving spring-loaded stop platelets, which project at the surface of the workpiece holding fixture, but which can be brought into a pushed back position. The operation of the boring machine is simplified and facilitated in that the multi-spindle boring assembly is adjustable and lockable vertically to the longitudinal sides of the workpiece holder, that "n" stop strips with holding fixtures for stop receivers are combined into a stop roller with n angles in the cross-section, that the stop roller can be brought into n angular positions below the workpiece holder, whereby the stop platelets of the stop rail facing an opening in the workpiece holder project through this opening.
