Universal machining center for 5-axis machining

 Equipped with a front table support, the Umill 750- a new universal and vertical CNC machining center - is capable of milling parts featuring an edge size of 530 x 530 x 417 mm and a weight of up to 400 kg using highly precise and highly efficient, simultaneous 5-axis machining. Its compact design in cast iron and welded steel, optimised by FEM analysis, with direct drives in X-Y-Z and standard linear scales among its features, guarantees the maximum in rigidity and thermosymmetry and the highest precision and an excellent surface quality of the workpiece. With its important technological and architectural innovations, the new Umill 750 creates optimumconditions for high-quality production.
