How much does the HNK NT-10/12F cost?
Price estimate
We do not have a price for the HNK NT-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 NT-10/12F is the smallest CNC vertical turning lathe in the NT series: a 1,000 mm (39.4 in) table, 1,250 mm (49.2 in) of swing and cutting diameter, and a turning height of 800 mm (31.5 in). It is also the fastest. The table runs to about 450 rpm in two speed steps, which no larger NT matches, so small rings and discs can be cut at a sensible surface speed.
The cross rail is a fixed type. That keeps the structure simple, but the 800 mm (31.5 in) under the rail is all the height there is, and the ram head has to reach the cut with its 750 mm (29.5 in) of Z travel. X travel runs from -200 to +795 mm (-7.9 to +31.3 in), so the tool can pass 200 mm beyond the table centre for facing and boring through the middle. The ram is 200 x 200 mm (7.9 x 7.9 in) and takes 40 x 40 mm (1.6 x 1.6 in) shank tools.
Table load is 4,500 kg (9,921 lb), and the table is driven by an A.C 30/37 kW (40.2/49.6 hp) motor, a cont/30min pair of ratings. Next up is the NT-12/16F, which keeps the fixed rail but moves to a 1,250 mm (49.2 in) table and 8,000 kg (17,637 lb). HNK lists Fanuc 31i-B and Siemens 840D as the controls.
HNK marks turning height, table speed and Z travel with a star, meaning these items can be changed to the customer's requirements. Treat those three rows as the catalogue starting point and confirm them on the quotation.

Strengths & Limitations
Strengths
- Highest table speed in the NT series at about 450 rpm, in two steps
- A.C 30/37 kW (40.2/49.6 hp) table drive on a 1,000 mm (39.4 in) table
- X travel from -200 to +795 mm (-7.9 to +31.3 in) lets the tool cross the table centre
- Control row lists both Fanuc 31i-B and Siemens 840D
Limitations
- Fixed cross rail: turning height stays at 800 mm (31.5 in) unless ordered differently
- Table load of 4,500 kg (9,921 lb) is the lowest in the series
- No milling spindle or C-axis row in the table; HNK lists those on the VTC series

Frequently Asked Questions
01
The table is 1,000 mm (39.4 in) in diameter and the maximum swing and cutting diameter is 1,250 mm (49.2 in). Turning height is 800 mm (31.5 in) and the table carries up to 4,500 kg (9,921 lb). HNK notes that the turning height can be changed to the customer's requirements.
02
No. HNK's table gives the cross rail as a fixed type on this model. Vertical reach comes from the ram head alone, which has 750 mm (29.5 in) of Z travel. In the NT series the stepped cross rail starts with the NT-12/16, which moves in 250 mm (9.8 in) steps.
03
The table speed for turning is given as a maximum of about 450 rpm in two steps, driven by an A.C motor rated 30/37 kW (40.2/49.6 hp) on a cont/30min basis. The speed row carries HNK's star mark, so it can be specified differently.
04
HNK's specification table lists Fanuc 31i-B and Siemens 840D in the control row, the same pair shown for every size in the NT series. The page does not say which one is the base fit, so name the control when asking for a quotation.
