MAXIMA

VARNSDORF MAXIMA CNC Horizontal milling and boring machine

Machine design is based on design groups of WRD machines, which are arranged in a cross -bed design.
Power machining of extremely heavy and large workpieces from several sides.
Machine can be extended with a wide selection of technological accessories that significantly widen the machine technological utility value.
Either HEIDENHAIN TNC 640, SINUMERIK 840D SL or FANUC 31icontrol system can be selected for controlling the machine.





    The horizontal table-type boring machines MAXIMA I / II are another representative of the CNC generation of TOS VARNSDORF machines, which excel in the top level of performance parameters and a user comfort based on technically advanced concept and a broad off er of variants and user functions. The structure of the machine is based on structural groups of the WRD machines, which are arranged in a cross-mounting of the table-type machines. The MAXIMA boring machines are characterized by a modern technical design of the structure and high level of performance. The MAXIMA machines are equipped with a RAM and a work spindle. The machine can be supplemented with a series of technological devices, which greatly extend the machine‘s potentialities.
