The extremely compact machine bed of the travelling column machining centres is a heat-treated, welded steel structure that provides a torsion-resistant and stable base for all components and machining operations. The production of large and heavy workpieces up to 8,000 kg is enabled by a powerful motor spindle with 46 kW spindle power, a torque of up to 170 Nm and a spindle speed of up to 15,000 rpm (18,000 rpm HSK-A63). Both spindle versions are grease-lubricated. The new versions of the previous model support complete machining of very long and heavy workpieces without reclamping.
