How much does the HNK VTC-16/20F cost?
Price estimate
We do not have a price for the HNK VTC-16/20F 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-16/20F is the widest fixed-rail turning center HNK lists: 2,000 mm (78.7 in) of swing and cutting diameter over a 1,600 mm (63.0 in) table, under a rail that does not move. Turning height is 900 mm (35.4 in).
Large flat parts are where turn-mill pays off most clearly. A slewing bearing ring or a big flange has dozens of bolt holes on a pitch circle, and moving a part that size to a drilling machine means a crane lift and a second alignment. Here the table indexes the ring in 0.001 degree increments, turning at 0 to 2.5 rpm as a C-axis, and the ISO 50 spindle drills and taps in place.
That spindle runs to about 2,500 rpm on an A.C 15/18.5 kW (20.1/24.8 hp) motor, cont/30min. The table takes 10,000 kg (22,046 lb) and reaches about 250 rpm in two steps with an A.C 37/45 kW (49.6/60.3 hp) drive.
X travel runs from -200 to +1,170 mm (-7.9 to +46.1 in), and Z travel is 900 mm (35.4 in). The ram measures 240 x 240 mm (9.4 x 9.4 in). HNK lists Fanuc 31i-B and Siemens 840D. Taller work in this swing goes to the VTC-16/20 at 1,660 mm (65.4 in) or the VTC-16/20R at 1,600 mm (63.0 in).

Strengths & Limitations
Strengths
- 2,000 mm (78.7 in) swing on a fixed-rail turning center
- C-axis table at 0 to 2.5 rpm with 0.001 degree indexing for bolt-circle work
- 10,000 kg (22,046 lb) table load
- ISO 50 milling spindle to about 2,500 rpm
Limitations
- 900 mm (35.4 in) turning height has to cover part, fixture and milling tool
- Milling motor is A.C 15/18.5 kW (20.1/24.8 hp), unchanged from the VTC-12/16F
- Table speed tops out at about 250 rpm

Frequently Asked Questions
01
Wide, low parts that need both turning and milling or drilling. It combines a 2,000 mm (78.7 in) swing and a fixed cross rail at 900 mm (35.4 in) of turning height with an ISO 50 milling spindle and a C-axis table.
02
HNK lists C-axis indexing of 0.001 degree, which is the increment and not a positioning accuracy. No accuracy or repeatability figure is given on the page. The table speed for indexing is 0 to 2.5 rpm.
03
Both have a 1,600 mm (63.0 in) table, 2,000 mm (78.7 in) swing, a fixed rail and 10,000 kg (22,046 lb) of load. The VTC-16/20F adds the milling spindle and C-axis and has a 240 x 240 mm (9.4 x 9.4 in) ram, where the NT-16/20F has a 200 x 200 mm (7.9 x 7.9 in) ram and turns only.
04
Two motors are listed: A.C 37/45 kW (49.6/60.3 hp) for the table and A.C 15/18.5 kW (20.1/24.8 hp) for the milling spindle, both given on a cont/30min basis.
