Machine tool for boring workpieces comprises elongated bench-type body with extrusion part with full-length hollow chambers parallel to longitudinal extension and closed at side ends by plate-type end members

摘要

The machine tool has an elongated bench-type base body (10) with spindle connection (14) in the centre and a cooling duct (24) leading from here to the cutter supports (19). The base body has an extrusion part (22) with full-length hollow chambers (24,26) formed parallel to the longitudinal extension and closed at the side ends (18) by plate-type end members (32). The cutter supports can be displaced relative to the longitudinal extension of the extrusion part.
