VARNSDORF WRD 180 H Floor type horizontal boring mill
WRD 180 H hydrostatic floor-type horizontal boring and milling machines are designed to serve for precise coordinate drilling, boring, milling, and thread cutting.
They are particularly suitable for the machining of box-, plate- and complex-shape work pieces made of cast iron, cast steel, steel or other materials machinable with cutting tools, and for large and very large size and weighty components.
The machines are well usable for batch production and complex process applications.
Machine are offered with three type of working spindel diameter (160, 180 and 200).
The machines are continuously controlled in four axes (X – base cross travelling, Y – headstock vertical adjustment, Z – sliding block longitudinal travel and W – working spindle longitudinal travel).
They can be extended with a wide selection of technological accessories that significantly widen the machine technological utility value.
HEIDENHAIN TNC 640, Sinumerik 840 D-SL or FANUC 31i control system can be selected for controlling the machine.
The largest, heaviest and most powerful, this is a representative of fully hydrostatic WRD 180 H machines. Thanks to excellent properties of hydrostatic guide, the machines are designed for the most demanding machining methods. The WRD 180 H machines are designed for precise line-coordinate drilling, boring, milling and thread cutting. They are particularly suitable for machining of box- and plate-type workpieces and complicated workpieces from cast-iron, steel cast-iron, steel and other machinable materials, mainly large as well as the largest sizes up to 200 tons.
