How much does the HNK VTC-12/16R cost?
Price estimate
We do not have a price for the HNK VTC-12/16R 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
The HNK VTC-12/16R does not follow the pattern of the VTC models around it. Its table is 1,200 mm (47.2 in), not the 1,250 mm (49.2 in) of the VTC-12/16; its control is listed as Fanuc 0i-T, with Fanuc 31i in braces; and its cross rail moves 300 mm (11.8 in) x 2steps. HNK's page does not explain the R, but the table describes a lighter, simpler turning center in the 1,600 mm (63.0 in) swing class.
Lighter shows in three rows. Table load is 7,000 kg (15,432 lb). The table motor is A.C 30/37 kW (40.2/49.6 hp), cont/30min, the rating used on the smallest VTC. And the milling spindle tops out at about 2,000 rpm, though its motor is the same A.C 15/18.5 kW (20.1/24.8 hp) and the taper is ISO 50.
Turning height is 1,200 mm (47.2 in) and the table reaches about 340 rpm in two steps. X travel is -100 to +970 mm (-3.9 to +38.2 in), so the tool crosses the centre by 100 mm, half the overtravel of the other VTC sizes. Z travel is 900 mm (35.4 in) and the ram 240 x 240 mm (9.4 x 9.4 in).
C-axis table speed is 0 to 3 rpm with 0.001 degree indexing. Where a 31i-class control or the full 8,000 kg (17,637 lb) is needed, the VTC-12/16 is the model to compare.

Strengths & Limitations
Strengths
- 1,200 mm (47.2 in) of turning height with a rail that moves 300 mm (11.8 in) x 2steps
- Milling spindle with ISO 50 taper and an A.C 15/18.5 kW (20.1/24.8 hp) motor
- Fanuc 0i-T listed, with Fanuc 31i shown in braces
- C-axis indexing of 0.001 degree at 0 to 3 rpm
Limitations
- 7,000 kg (15,432 lb) table load, below the 8,000 kg (17,637 lb) of the VTC-12/16
- Milling speed is about 2,000 rpm, not the about 2,500 rpm of the VTC-12/16
- X travel passes the centre by only 100 mm
- Siemens 840D is not in this model's control row

Frequently Asked Questions
01
The control system row reads Fanuc 0i-T {Fanuc 31i}. HNK's page has no legend for the braces. On other HNK tables a figure in braces is labelled as an option, so confirm with the maker whether the 31i is an alternative at order.
02
The VTC-12/16R has a 1,200 mm (47.2 in) table, 7,000 kg (15,432 lb) load, an A.C 30/37 kW (40.2/49.6 hp) table motor and about 2,000 rpm on the milling spindle. The VTC-12/16 has a 1,250 mm (49.2 in) table, 8,000 kg (17,637 lb), A.C 37/45 kW (49.6/60.3 hp) and about 2,500 rpm.
03
300 mm (11.8 in) x 2steps, as HNK prints it. The other stepped-rail machines near this size use 250 mm (9.8 in) increments, for example the VTC-12/16 with 3 steps.
04
Up to about 340 rpm for turning, in two steps, and 0 to 3 rpm when used as the C-axis for milling and drilling. The turning speed row is star-marked as changeable to the customer's requirements.
