Hankook’s 45 tonne turning and boring machine packs a lot of torque
1 min read
Hankook's VTC-200E elevating cross rail turning and boring machine provides a heavy duty machining platform weighing in at 45 tonnes able to process components weighing up to 12 tonnes on its 2 m table. The table is powered by a 55kW, two-speed motor programmable up to 200 rpm delivering 40,400 Nm of torque. The maximum turning envelope on components is up to 2.5 m dia by 2 m high.
The Hankook VTC-200E machine has a 240 mm square ram and BT50 taper tool head having a 22 kW drive. The tool head is serviced from a magazine supplying up to 12 turning and 12 driven tools which can weigh up to 50 kg and through-the-tool coolant supply is standard.
Spindle speed on the Hankook VTC-200E is programmable between 30 and 3,000 rpm with both the vertical Z-axis and saddle X-axis having travels of 1,500 mm. The cross rail W-axis travel is 1,000 mm at a rapid traverse rate of 300 mm/min.
The C-axis is driven by a 9 kW servomotor and will rotate at up to 2.5 rpm with a programmable feedrate between 0 and 900°/min. It has the ability to index within 0.001°. Control is via Fanuc 32i and options include higher accuracy positioning through linear scales in both X and Z axes. Machine probing and tool setting is also available.
