VARNSDORF WRD 170 Floor type horizontal boring mill
The biggest type of floor type horizontal boring machines manufactured by TOS VARNSDORF a.s.
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 31i control system can be selected for controlling the machine.
On the customer’s wish the machine can be supplied also in design with spindle diameter of 160 mm.
The WRD 170 (Q) machine is the largest and heaviest representative of fl oor-type machine with linear guide in the manufacturing portfolio of TOS VARNSDORF a.s. The machines are designed for precise line-coordinate drilling, boring, milling and thread cutting. WRD 170 (Q) is suitable for machining of box- and plate-type workpieces and complicated workpieces from castiron, steel cast-iron, steel and other machinable materials, mainly large as well as the largest sizes up to 150 tons. The machine can be supplemented with a series of technological devices, which greatly extend the machine‘s fl exibility.
WRD 170 – basic version of the machine
WRD 170 Q – version with an automatic tool change
The machines are controlled in 5 axes (X, Y, Z, W and V – additional rotary table)
