How much does the HNK VTC-60/70 cost?
Price estimate
We do not have a price for the HNK VTC-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
Milling power steps up sharply on the HNK VTC-60/70. The milling spindle motor is A.C 37/45 kW (49.6/60.3 hp), cont/30min, where the VTC-50/60 has A.C 22/26 kW (29.5/34.9 hp). Spindle speed comes down to about 1,500 rpm, and the taper stays ISO 50.
That combination, more power at less speed, is a large-cutter specification: big face mills, heavy drills and boring bars on a part that may weigh as much as the 150,000 kg (330,688 lb) the table is rated for. The table is 6,000 mm (236.2 in) in diameter, with 7,000 mm (275.6 in) of swing and cutting diameter and 3,500 mm (137.8 in) of turning height.
The ram that carries the spindle is listed at 400 x 400, 500 x 500 or 600 x 600 mm (15.7 x 15.7, 19.7 x 19.7 or 23.6 x 23.6 in), and Z travel at 2,200/2,500/3,000/3,500 mm (86.6/98.4/118.1/137.8 in). Turning tools use 60 x 60 mm (2.4 x 2.4 in) shanks.
An A.C 190 kW (254.8 hp) motor turns the table at up to about 40 rpm in two steps, and in C-axis mode the table runs at 0 to 0.3 rpm with 0.001 degree indexing. X travel is -200 to +3,800 mm (-7.9 to +149.6 in). HNK's cross rail entry for this model is printed without a unit, so the rail travel has to be confirmed with the maker. Controls listed: Fanuc 31i-B, Siemens 840D.

Frequently Asked Questions
01
The VTC-60/70 has an A.C 37/45 kW (49.6/60.3 hp) milling motor and about 1,500 rpm. The VTC-50/60 has A.C 22/26 kW (29.5/34.9 hp) and about 2,000 rpm. Both use an ISO 50 taper.
02
150,000 kg (330,688 lb), on a 6,000 mm (236.2 in) table. Swing and cutting diameter are 7,000 mm (275.6 in) and the maximum turning height 3,500 mm (137.8 in).
03
The maker's table does not give a usable figure: the entry for this model lacks its unit. The turning-only NT-60/70, which shares the table and height, lists 250 mm (9.8 in) x 9 steps, but confirm the VTC figure with HNK.
04
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), 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). HNK does not name a default.
