VARNSDORF WRD 130 / 150 Floor type horizontal boring mill
Twin-type of machines of the same concept and frame, but different main motor outputs, different headstocks and spindle speeds.
Intented for precision and high-efficient coordinate boring, drilling, milling and thread-cutting particularly in the case of large-scale, heavy and structurally difficult work-pieces made of cast iron, cast steel and steel.
According to process needs, the machine can be extended with a clamping field consisting of clamping plates or with one or more additional tables.
Machines can be extended with a wide selection of technological accessories that significantly widen the machine technological utility value.
Either SINUMERIK 840D SL, HEIDENHAIN TNC 640 or FANUC 31icontrol system can be selected for controlling the machine.
On the customer’s wish the WRD 150 type can be supplied also in design with spindle diameter of 160 mm.
The WRD 130 / 150 (Q) boring machine are characterized by a modern technical design of the structure and high level of performance. The machine can be supplemented with a series of technological devices, which greatly extend the machine‘s potentialities. The machines are designed for precise, highly productive line-coordinate drilling, boring, milling and thread cutting, especially large and heavy workpieces or complicated workpieces from cast-iron, steel cast-iron and steel. The machines can be supplemented with an attachment fi eld composed of attachment plates or one as well as more tables.
