How much does the HNK VTC-10/12F cost?
Price estimate
We do not have a price for the HNK VTC-10/12F 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-10/12F is the entry size of the VTC vertical turning centers: a 1,000 mm (39.4 in) table with a C-axis, plus a live milling spindle in the ram. HNK's point for the series is that an indexing table and a live spindle let the machine mill and tap after turning, so a part is finished in a single setup.
On this size the milling spindle runs to about 2,500 rpm on an A.C 11/15 kW (14.8/20.1 hp) motor, cont/30min, with an ISO 50 taper. That is the smallest milling motor in the VTC range, suited to bolt circles, keyways and light face milling on a turned part and not to heavy stock removal. For contouring and positioning the table turns at 0 to 3 rpm as a C-axis and indexes in 0.001 degree increments.
As a lathe it mirrors the NT-10/12F: 1,250 mm (49.2 in) swing, 800 mm (31.5 in) turning height, about 450 rpm in two steps, 4,500 kg (9,921 lb) of table load, an A.C 30/37 kW (40.2/49.6 hp) table motor and a fixed type cross rail. The ram is larger, 240 x 240 mm (9.4 x 9.4 in) against 200 x 200 mm (7.9 x 7.9 in) on the NT-10/12F, to house the spindle.
Travels are -200 to +795 mm (-7.9 to +31.3 in) in X and 750 mm (29.5 in) in Z. Fanuc 31i-B and Siemens 840D are the listed controls.

Limitations
- Milling motor is A.C 11/15 kW (14.8/20.1 hp), the smallest in the series
- Fixed cross rail and 800 mm (31.5 in) of turning height
- 4,500 kg (9,921 lb) table load

Frequently Asked Questions
01
Mill, drill and tap. The VTC-10/12F adds a milling spindle (ISO 50, about 2,500 rpm, A.C 11/15 kW (14.8/20.1 hp)) and a C-axis table with 0.001 degree indexing. Table size, swing, turning height and the 4,500 kg (9,921 lb) load are the same as on the NT-10/12F.
02
The motor for the milling spindle is rated A.C 11/15 kW (14.8/20.1 hp) on a cont/30min basis, with a top speed of about 2,500 rpm. HNK publishes no torque figure. The VTC-12/16F one size up has A.C 15/18.5 kW (20.1/24.8 hp).
03
The table doubles as the C-axis. HNK lists a table speed for indexing of 0 to 3 rpm and C-axis indexing of 0.001 degree, separate from the turning speed range that tops out at about 450 rpm.
04
ISO 50, as on every VTC size. Turning tools are held on a 40 x 40 mm (1.6 x 1.6 in) shank in the 240 x 240 mm (9.4 x 9.4 in) ram. The page does not describe how tools are changed, so ask what tool magazine is included.
