How much does the HNK VTC-12/16F cost?
Price estimate
We do not have a price for the HNK VTC-12/16F 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
Three VTC models share a 1,600 mm (63.0 in) swing, and the HNK VTC-12/16F is the fixed-rail one. It has a 1,250 mm (49.2 in) table, a fixed type cross rail and 900 mm (35.4 in) of turning height. The VTC-12/16 has a stepped rail and 1,300 mm (51.2 in); the VTC-12/16R is a separate design with a 1,200 mm (47.2 in) table.
Compared with that R model, the F machine is the heavier-duty choice despite its lower height. It carries 8,000 kg (17,637 lb) where the VTC-12/16R carries 7,000 kg (15,432 lb), it has the A.C 37/45 kW (49.6/60.3 hp) table motor, and its milling spindle reaches about 2,500 rpm. The control row reads Fanuc 31i-B, Siemens 840D.
The milling spindle has an ISO 50 taper and an A.C 15/18.5 kW (20.1/24.8 hp) motor, cont/30min. With the table indexing at 0.001 degree and turning at 0 to 3 rpm as a C-axis, drilling patterns and milled flats can follow turning without moving the part to another machine.
Table speed for turning is about 360 rpm in two steps. X travel is -200 to +970 mm (-7.9 to +38.2 in), Z 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 VTC-12/16F has a fixed rail and 900 mm (35.4 in) of turning height. The VTC-12/16 has a rail moving 250 mm (9.8 in) x 3 steps and 1,300 mm (51.2 in). The VTC-12/16R has a 1,200 mm (47.2 in) table, 1,200 mm of turning height, a 7,000 kg (15,432 lb) load and a Fanuc 0i-T control.
02
An ISO 50 milling spindle running to about 2,500 rpm, driven by an A.C motor rated 15/18.5 kW (20.1/24.8 hp), cont/30min. It shares that spindle specification with the VTC-12/16 and the VTC-16/20F.
03
Table diameter 1,250 mm (49.2 in), swing and cutting diameter 1,600 mm (63.0 in), turning height 900 mm (35.4 in), table speed up to about 360 rpm in two steps and a table load of 8,000 kg (17,637 lb).
04
HNK marks maximum turning height with a star and says starred items can be changed according to the customer's requirements. As catalogued, though, the rail is fixed, and the stepped-rail VTC-12/16 is the listed way to get more height.
