The medium-small sized PAMA Vertiram TT vertical machining centers combine dynamics and high spindle speed, whereas the medium-large size combines maximum damping, maximum rigidity and high spindle torque. Both guarantee optimal workpiece precision. The wide range of the PAMA Vertiram TT is able to satisfy the most difficult machining applications for the majority of small, medium and large-sized components for which vertical machining is preferred. The PAMA Vertiram TT machines can be equipped with a mobile crossrail to increase versatility and better adapt the spindle height to the workpiece being machined. The medium-large sized PAMA Vertiram TT machines have roller guideways on the linear axes to optimize the axes dynamics, whereas the medium-large sized machines have preloaded hydrostatic guideways to optimize the advantages of rigidity and vibration damping. The focal point of the PAMA Vertiram TT machine is the ram, guided inside the headstock by hydrostatic pads, which has a real-time feedback system to compensate for any elongation caused by temperature variations. This solution guarantees maximum precision and rigidity together with high damping of the vibrations, very close to where they are generated. The structures of the PAMA Vertiram TT machine were studied using modern finite element analysis techniques with the purpose of optimising the masses and guarantee high static and dynamic rigidity, as well as greater thermal symmetry. Depending on the PAMA Vertiram TT size and customer requirements, the machine can be configured with different ram solutions: ram with driver ram with boring bar ram with integrated C axis
