How much does the HNK VTC-16/20R cost?
Price estimate
We do not have a price for the HNK VTC-16/20R 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
Like its smaller R sibling, the HNK VTC-16/20R is the Fanuc 0i-T machine in its size class. It has a 1,600 mm (63.0 in) table and 2,000 mm (78.7 in) of swing, the same as the VTC-16/20, but the control row reads Fanuc 0i-T with Fanuc 31i in braces, and Siemens 840D is absent.
The mechanical differences from the VTC-16/20 are small and all point the same way. Table load is 8,000 kg (17,637 lb), not 10,000 kg (22,046 lb) as on the VTC-16/20. Turning height is 1,600 mm (63.0 in), a little under the 1,660 mm (65.4 in) of the VTC-16/20. X travel begins at -100 mm, so the range is -100 to +1,170 mm (-3.9 to +46.1 in). The milling spindle is limited to about 2,000 rpm.
What stays the same is the power. The table motor is A.C 37/45 kW (49.6/60.3 hp) and the milling motor A.C 15/18.5 kW (20.1/24.8 hp), both cont/30min, with an ISO 50 taper. Table speed for turning is about 250 rpm in two steps. As a C-axis the table runs at 0 to 3 rpm, slightly faster than the 0 to 2.5 rpm of the VTC-16/20, and indexes at 0.001 degree.
The cross rail moves 250 mm (9.8 in) x 3steps, Z travel is 900 mm (35.4 in) and the ram is 240 x 240 mm (9.4 x 9.4 in).

Frequently Asked Questions
01
The table gives one clear reason: the control. The VTC-16/20R lists Fanuc 0i-T {Fanuc 31i}, the VTC-16/20 lists Fanuc 31i-B, Siemens 840D. In exchange the R model carries 8,000 kg (17,637 lb) where the VTC-16/20 carries 10,000 kg (22,046 lb), and it mills at about 2,000 rpm where the VTC-16/20 reaches about 2,500 rpm.
02
Up to 2,000 mm (78.7 in) in swing and cutting diameter, 1,600 mm (63.0 in) in turning height and 8,000 kg (17,637 lb) on the 1,600 mm (63.0 in) table.
03
Not in motor rating. Table drive is A.C 37/45 kW (49.6/60.3 hp) and the milling spindle motor A.C 15/18.5 kW (20.1/24.8 hp), the same as the VTC-16/20F. The lower figures are table load and milling speed.
04
100 mm. HNK lists the horizontal travel of the ram head as -100 to +1,170 mm (-3.9 to +46.1 in). If a boring or facing operation has to run further across the centre line, compare the VTC-16/20, which starts at -200 mm.
