ABSTRACT:
An apparatus is disclosed for the production of prismatic or truncated-pyramid-shaped beams from boles (4) by edging the latter with the aid of at least two machining tools (13, 14) wherein a relative movement is generated between the bole (4) to be machined and the machining tools (13, 14). In order to be able to manufacture conical beams, the machining tools are adjustable during edging transversely to the direction of the longitudinal extension of the bole (4) the result being a linear relative motion of the machining tools (13, 14) inclined under an acute angle with respect to the axis of the bole (4).
