摘要： A vertical internal push broaching machine comprises a machine column and a workpiece lifting table which is guided for displacement on carriage guideways. Underneath the lifting table, a feeder carriage is disposed vertically displaceably on guideways. These guideways can be separate from the carriage guideways. The lifting table is actuated by means of a single elevating drive which is disposed behind the plane spanned by the carriage guideways.
