How much does the HNK NT-12/16F cost?
Price estimate
We do not have a price for the HNK NT-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
Two NT machines share the 1,250 mm (49.2 in) table, and the HNK NT-12/16F is the low one. Its cross rail is fixed, the maximum turning height is 900 mm (35.4 in), and the swing and cutting diameter is 1,600 mm (63.0 in). The NT-12/16 has the same table and swing but a stepped rail and 1,300 mm (51.2 in) of turning height.
So the choice between the two is about part height, nothing else. Load is 8,000 kg (17,637 lb) on both. Both use the A.C 37/45 kW (49.6/60.3 hp) table motor (cont/30min) and reach about 360 rpm in two steps. If the work is bearing rings, flanges, brake discs or valve bodies that never stand taller than 900 mm (35.4 in), the fixed rail is one less axis to position and clamp.
The ram head travels 900 mm (35.4 in) in Z and from -200 to +970 mm (-7.9 to +38.2 in) in X. Ram section is 200 x 200 mm (7.9 x 7.9 in), with 40 x 40 mm (1.6 x 1.6 in) tool shanks. Note that Z travel equals the turning height here, so a tall part leaves little room for a long boring bar above it.
Fanuc 31i-B and Siemens 840D are the controls HNK lists. Turning height, table speed and Z travel are star-marked rows that HNK will change to suit the customer.

Strengths & Limitations
Strengths
- 1,600 mm (63.0 in) swing and 8,000 kg (17,637 lb) table load on a fixed-rail machine
- A.C 37/45 kW (49.6/60.3 hp) table motor, a step above the 30/37 kW (40.2/49.6 hp) of the NT-10/12F
- Table speed to about 360 rpm in two steps
- Same 900 mm (35.4 in) Z travel as the stepped-rail NT-12/16
Limitations
- Turning height is 900 mm (35.4 in), against 1,300 mm (51.2 in) on the NT-12/16
- Cross rail is a fixed type, so the height cannot be reset between jobs
- Ram is 200 x 200 mm (7.9 x 7.9 in); the 240 x 240 mm (9.4 x 9.4 in) ram starts at the NT-20/25

Frequently Asked Questions
01
HNK's page does not spell out the letter, but the table shows the difference: the NT-12/16F has a fixed type cross rail and 900 mm (35.4 in) of turning height, while the NT-12/16 has a rail that moves 250 mm (9.8 in) x 3 steps and 1,300 mm (51.2 in) of turning height. Table, swing, load and motor are the same.
02
Table diameter is 1,250 mm (49.2 in), maximum swing and cutting diameter 1,600 mm (63.0 in), turning height 900 mm (35.4 in) and table load 8,000 kg (17,637 lb).
03
Horizontally from -200 to +970 mm (-7.9 to +38.2 in), which takes the tool past the table centre, and 900 mm (35.4 in) vertically. The ram itself is 200 x 200 mm (7.9 x 7.9 in). HNK star-marks the Z travel as changeable to order.
04
The NT table has no milling spindle or C-axis rows. HNK describes the NT series as a CNC vertical turning lathe and puts the live spindle and indexing table on the VTC series; the VTC-12/16F is the matching size with a 1,250 mm (49.2 in) table.
