Vertical machining centers, traveling gantry
The medium-small sized PAMA Vertiram GT 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 work precision.
The wide range, PAMA Vertiram GT 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.
PAMA Vertiram GT machines can be equipped with mobile crossrail to increase versatility and better adapt the spindle height to the workpiece being machined.
The medium-large sized PAMA Vertiram GT machines have roller guideways on the linear axes to make full use of the dynamics on the axes, whereas the medium-large sized machine has preloaded hydrostatic guideways to make full use of all the advantages of rigidity and vibration damping.
The focal point of the PAMA Vertiram GT 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 GT 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 GT 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
The CNC attachment heads are thermal stabilised with fluid recirculation at a controlled temperature, whereas to reach high speeds, high precision and maximum wear resistance of the kinematic units, lubrication is provided by air-oil or climatised oil recirculation systems.
Depending on working requirements, PAMA Vertiram GT machines can be customised and configured by selecting from:
- 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 PAMA Vertiram GT range can be configured by selecting from among Siemens, Heidenhain and Fanuc CNC.
