How much does the HNK NT-60/70 cost?
Price estimate
We do not have a price for the HNK NT-60/70 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
Table load more than doubles at the HNK NT-60/70. The 6,000 mm (236.2 in) table is rated for 150,000 kg (330,688 lb), where the NT-50/60 beneath it stops at 60,000 kg (132,275 lb). Swing and cutting diameter are 7,000 mm (275.6 in) and the turning height is 3,500 mm (137.8 in).
The structure above the table is scaled to match. Ram sections of 400 x 400, 500 x 500 and 600 x 600 mm (15.7 x 15.7, 19.7 x 19.7 and 23.6 x 23.6 in) are listed, so the smallest ram here equals the largest on the NT-50/60. Z travel choices are 2,200/2,500/3,000/3,500 mm (86.6/98.4/118.1/137.8 in). The cross rail moves 250 mm (9.8 in) x 9 steps, the most steps of any NT that uses the 250 mm increment.
An A.C 190 kW (254.8 hp) motor drives the table to about 40 rpm in two steps. This is the largest A.C drive in the series; the two machines above it are listed with D.C motors. X travel is -200 to +3,800 mm (-7.9 to +149.6 in) and the tool shank is 60 x 60 mm (2.4 x 2.4 in).
A machine of this weight class is a foundation project as much as a machine purchase. HNK's page gives no machine weight or floor dimensions, so those have to come with the quotation. Controls: Fanuc 31i-B, Siemens 840D.

Frequently Asked Questions
01
150,000 kg (330,688 lb) on the table. The NT-50/60 is rated at 60,000 kg (132,275 lb), so this is the size to look at once the part and its fixture pass that mark.
02
The table lists 400 x 400/500 x 500/600 x 600 mm (15.7 x 15.7/19.7 x 19.7/23.6 x 23.6 in). It is paired with a Z travel of 2,200, 2,500, 3,000 or 3,500 mm (86.6, 98.4, 118.1 or 137.8 in), and the tool shank is 60 x 60 mm (2.4 x 2.4 in).
03
It moves vertically 250 mm (9.8 in) x 9 steps. With a 3,500 mm (137.8 in) maximum turning height, the rail is set for each job and the ram does the rest of the vertical travel.
04
Maximum swing and cutting diameter is 7,000 mm (275.6 in) over a 6,000 mm (236.2 in) table. The ram head reaches +3,800 mm (+149.6 in) from centre and 200 mm to the far side.
