The Speedram boring and milling machines are able to combine maximum damping, maximum rigidity and high torque to the spindle with optimal working precision. They are able to satisfy also the most difficult applications when machining medium- and large-sized components, for which horizontal machining is preferable. The Speedram boring and milling machines adopt preloaded hydrostatic guides on the X and Y axes to make full use of the advantages of rigidity and damping of the vibrations. The focal point of the PAMA Speedram machine is the ram, guided inside the headstock by hydrostatic pads, and equipped with a boring bar exclusively with mechanical transmission. Both the ram as well as the boring bar have a feedback system to compensate for any elongations 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 Speedram boring and milling machines 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 optimum thermal symmetry. Depending on workpiece requirements, the PAMA Speedram machine can be customised and configured by selecting from a vast assortment of standard or customised CNC attachment heads a wide assortment of milling or turning tables a wide assortment of tool magazines and tool and CNC attachment head magazines From a software point of view, the range of the PAMA Speedram boring and milling machines can be configured by selecting from among CNC Siemens, Heidenhain and Fanuc.
