How much does the HNK HKDB-130(1.2Mx7M) cost?
Price estimate
We do not have a price for the HNK HKDB-130(1.2Mx7M) 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 HKDB-130(1.2Mx7M) is the wide-table version of the seven-metre duplex boring machine. Its table is 1,200 x 7,000 mm (47.2 x 275.6 in), and the two spindle ends open from 300 to 1,500 mm (11.8 to 59.1 in), where the HKDB-130(1Mx7M) stops at 1,300 mm (51.2 in).
Width runs through the whole specification. Each spindle head has 600 mm (23.6 in) of Z travel, a little more than the 1M machines, so the heads can still reach the faces of a narrow part when the gap is set wide for a broad one. A box-section frame, a transmission case for a large vehicle or a compressor crankcase can be bored through from both sides, the two bores sharing one axis because neither the part nor the heads have been repositioned.
That is the practical meaning of what HNK calls precision symmetrical machining. On a single-spindle boring mill the same job needs the table indexed half a turn, and the alignment of the two bores then depends on the table's indexing accuracy.
Other figures match the HKDB-130(1Mx7M): 7,000 mm (275.6 in) of X travel, 2,000 mm (78.7 in) of Y, 10,000 kg (22,046 lb) on the table, 22/26 kW (29.5/34.9 hp) per spindle (cont/30min) and 5 to 2,500 rpm on ISO No.50. The control is Fanuc 31i-B or Siemens 840D.

Strengths & Limitations
Strengths
- Spindle gap up to 1,500 mm (59.1 in) for wider parts
- 600 mm (23.6 in) of Z travel on each head
- 1,200 x 7,000 mm (47.2 x 275.6 in) table with 10,000 kg (22,046 lb) capacity
- Opposed bores machined on one axis without indexing the part
Limitations
- Table load is the same 10,000 kg (22,046 lb) as on the narrower 1M machine
- X travel of 7,000 mm (275.6 in); longer tables exist in the 1.2M width
- Minimum spindle gap is 300 mm (11.8 in)

Frequently Asked Questions
01
The distance between spindle ends adjusts from 300 to 1,500 mm (11.8 to 59.1 in) and the table is 1,200 mm wide. Subtract the tool lengths on both sides from the gap to get the widest part that can be machined.
02
HNK says the series machines both sides of a workpiece simultaneously for shorter cycle time and precision symmetrical machining. With two opposed heads the part is not turned round, so opposite bores are cut in the same clamping.
03
The HKDB-130(1.2Mx9M) with 9,000 mm (354.3 in) of X travel and the HKDB-130(1.2Mx13M) with 13,000 mm (511.8 in). Both keep the 1,200 mm table width, the spindle gap and the 22/26 kW (29.5/34.9 hp) motors of the HKDB-130(1.2Mx7M).
04
Each of the 2 spindle heads has a Ø130 spindle with ISO No.50 taper, 5 to 2,500 rpm, and a motor of 22/26 kW (29.5/34.9 hp) on HNK's cont/30min basis.
