How much does the HNK NT-12/16 cost?
Price estimate
We do not have a price for the HNK NT-12/16 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 NT-12/16 is where the NT series gets a movable cross rail. On a 1,250 mm (49.2 in) table with 1,600 mm (63.0 in) of swing and cutting diameter, the rail travels vertically in 3 steps of 250 mm (9.8 in), and the maximum turning height rises to 1,300 mm (51.2 in).
Why does that matter on a machine this size? With the rail set low, the ram works close to its housing on short parts and stays stiff. Raised, it clears a tall housing or a stacked fixture. The ram head's own Z travel is 900 mm (35.4 in), so reach to the bottom of a deep bore still depends on where the rail is parked. The fixed-rail NT-12/16F stops at 900 mm (35.4 in) of turning height.
Everything else matches that sibling. Table load is 8,000 kg (17,637 lb). The table motor is A.C 37/45 kW (49.6/60.3 hp) on a cont/30min basis, and the speed for turning tops out at about 360 rpm in two steps. X travel is -200 to +970 mm (-7.9 to +38.2 in), the ram measures 200 x 200 mm (7.9 x 7.9 in), and tools have 40 x 40 mm (1.6 x 1.6 in) shanks. The control is listed as Fanuc 31i-B, Siemens 840D.

Strengths & Limitations
Strengths
- Cross rail moves 250 mm (9.8 in) x 3 steps, the smallest NT with a movable rail
- 1,300 mm (51.2 in) turning height on a 1,250 mm (49.2 in) table
- 8,000 kg (17,637 lb) table load with an A.C 37/45 kW (49.6/60.3 hp) drive
- X travel reaches 200 mm past centre and out to +970 mm (+38.2 in)
Limitations
- Rail positions are stepped, 250 mm (9.8 in) apart, not continuously adjustable
- Z travel of 900 mm (35.4 in) is shorter than the 1,300 mm (51.2 in) turning height
- About 360 rpm at most; the NT-10/12F reaches about 450 rpm

Frequently Asked Questions
01
HNK gives the vertical travel of the cross rail as 250 mm (9.8 in) x 3 steps. The rail is set to one of the stepped heights for a job and the ram head then works within its 900 mm (35.4 in) of Z travel.
02
Look at the tallest part. The NT-12/16F has a fixed type cross rail and 900 mm (35.4 in) of turning height. The NT-12/16 turns up to 1,300 mm (51.2 in). Table diameter, swing, 8,000 kg (17,637 lb) load, motor and speed are identical in HNK's table.
03
The table gives a tool shank size of 40 x 40 mm (1.6 x 1.6 in) in a 200 x 200 mm (7.9 x 7.9 in) ram. HNK's page for the series does not describe a tool changer or magazine, so ask what tool handling is included.
04
No. Maximum turning height is one of three rows HNK marks with a star, along with table speed and Z travel, and the page states that starred items can be changed according to the customer's requirements.
