How much does the HNK HB-150 cost?
Price estimate
We do not have a price for the HNK HB-150 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 HB-150 is the top of the HB table-type boring mills, and its specification reads differently from the rest: most rows are ranges. X travel is 3,000 ~ 7,000 mm (118.1 ~ 275.6 in), Y is 2,300 ~ 4,000 mm (90.6 ~ 157.5 in), Z is 1,600 ~ 2,500 mm (63.0 ~ 98.4 in) and the W-axis 700 ~ 1,000 mm (27.6 ~ 39.4 in). The machine is configured to the job.
The spindle is fixed. It is Ø150 mm (5.9 in) with an ISO 50 taper, runs from 5 to 2,000 rpm, and has a 37/45 kW (49.6/60.3 hp) motor on a cont/30min basis, with 50/60 kW (67.1/80.5 hp) in braces. The HB-130 group below has 22/26 kW (29.5/34.9 hp), so this is a large jump in cutting power as well as in spindle stiffness.
Table size is 2,000 x 2,200 mm (78.7 x 86.6 in), with 2,500 x 3,000 mm (98.4 x 118.1 in) in braces, and the load on the rotary table is quoted as 15,000 ~ 35,000 kg (33,069 ~ 77,160 lb). Rotation is 1 rpm and indexing 0.001°.
At the long end of those ranges the HB-150 overlaps with floor-type machines. HNK's own HFB-150 has the same spindle diameter with a travelling column. The difference is that here the workpiece still rides on the machine's table and moves in X, which keeps set-up simple for parts within the load range.

Strengths & Limitations
Strengths
- Ø150 mm (5.9 in) spindle with 37/45 kW (49.6/60.3 hp), or 50/60 kW (67.1/80.5 hp) in braces
- X travel configurable from 3,000 to 7,000 mm (118.1 to 275.6 in)
- Y travel up to 4,000 mm (157.5 in)
- Rotary table load from 15,000 to 35,000 kg (33,069 to 77,160 lb)
Limitations
- Ranges mean the catalogue does not define one machine; every travel must be specified
- Maximum spindle speed of 2,000 rpm, the lowest in the HB series
- Table rotation speed of 1 rpm on the rotary table

Frequently Asked Questions
01
HNK lists X as 3,000 ~ 7,000 mm (118.1 ~ 275.6 in), Y as 2,300 ~ 4,000 mm (90.6 ~ 157.5 in) and Z as 1,600 ~ 2,500 mm (63.0 ~ 98.4 in) without tying them to sub-models. The page does not explain further; the reading is that travel lengths are selected at order.
02
The HB-150 motor is 37/45 kW (49.6/60.3 hp); the HB-130 motor is 22/26 kW (29.5/34.9 hp). Both are cont/30min ratings with a higher pair in braces. The HB-150 spindle is Ø150 mm (5.9 in) and tops out at 2,000 rpm, where the HB-130 spindle is Ø130 mm (5.1 in) and reaches 2,500 rpm.
03
A rotary table of 2,000 x 2,200 mm (78.7 x 86.6 in), with 2,500 x 3,000 mm (98.4 x 118.1 in) in braces. The load is 15,000 ~ 35,000 kg (33,069 ~ 77,160 lb), and indexing is 0.001° with pin location every 90°.
04
If the part is too heavy or too long for a moving table, yes. The HFB-150 is a floor type with a Ø150 mm (5.9 in) spindle and a rotary table for 30,000 kg (66,138 lb), and its column travels 4,000 ~ 30,000 mm (157.5 ~ 1,181.1 in) in X.
