OZKKM 5 Axis / FORNAX 900 Monoblock CNC Bridge Cutting Machine

OZKKM FORNAX is a 5-axis monoblock bridge saw machine that, thanks to the advanced functionality, allows every stone fabrication shop to be equipped with accurate and quick machines, without giving up quality. The standard versions of FORNAX is monoblock, i.e.: mounted on a monolithic structure of steel carpentry that assures utmost rigidity and stability levels, with no need of any concrete foundation. For this reason, if necessary, they can be easily moved elsewhere. The monoblock configuration can be exploited also for using these machines as “building“ equipment, i.e. it can be placed time by time near the factory where the coating, flooring, etc. are being performed.
OZKKM FORNAX is the result of the most advanced designing on computer and the massive use of FEM analysis in order to reach a very high rigidity level of the bridge and structures. Even though it is a sawing machine, both have technical solutions of a CNC machine. All the movements of the axes are on linear bearings which do not need to be adjusted. All the lubrication points have been gathered in areas which can easily be seen and reached, without disassembling guards or protections for facilitating ordinary maintenance. High level components are employed. The motors used are servo motors with precision reducers. Especially the high speed of the X axis allows to cut down idle times as much as possible with a productivity increase (the percentage of the time that the disc stays on the material is higher with respect to the time forplacing or returning to cut start).
The spindle, anchored in front of the beam to offer the utmost rigidity, can accommodate disks up to a diameter of 900 mm and ½” gas thread tools. It also warrants the choice of placing the cutting disc in axis with the head rotation center to reduce the efforts on the axis to zero for an excellent cutting quality. The inclination of the disc can be arranged automatically from 0° to 90° and the possibility to interpolate the X and Y axes make the machine suitable for repetitive processing and single details even with vertical, inclined, parallel, orthogonal, diagonal and curved cuts. The machines, in the standard version are equipped with a fixed table and can be tilted up to 80 ° by a hydraulic piston to facilitate the loading and unloading of the processed pieces.
