How much does the HNK HPF-15 cost?
Price estimate
We do not have a price for the HNK HPF-15 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 HPF-15 is a double-column machine rebuilt around one job: preparing forgings for medium-speed crankshafts. HNK lists what it does. It measures the forged raw material, marks the centre and the crankpin angles, faces the ends, and drills the flange holes.
The proportions are those of a crankshaft, not of a plate. The table is 1,500 x 8,000 mm (59.1 x 315.0 in) and travels 8,250 mm (324.8 in) in X, while the columns stand only 2,150 mm (84.6 in) apart. The spindle head has 2,600 mm (102.4 in) of Y and the ram 1,000 mm (39.4 in) of Z. Up to 2,000 mm (78.7 in) lies between table surface and spindle end, which leaves room for a forging on V-blocks.
Spindle speed is 3,000 rpm and the control is Fanuc 31i-B. Nothing else about the spindle is published: no taper, no power, no table load.

Strengths & Limitations
Strengths
- Measures, marks, faces and drills a crankshaft forging on one machine
- 8,250 mm (324.8 in) of X travel over a 1,500 x 8,000 mm (59.1 x 315.0 in) table
- Up to 2,000 mm (78.7 in) from table surface to spindle end
Limitations
- Only 2,150 mm (84.6 in) between the columns

Frequently Asked Questions
01
HNK says it is designed mainly for measuring the dimension of forged raw material, marking the centre of a job and the angle of the crankpin, facing the side of a job, and drilling and making holes on the flange, all within medium-speed crankshaft production.
02
Table 1,500 x 8,000 mm (59.1 x 315.0 in), X travel 8,250 mm (324.8 in), Y travel 2,600 mm (102.4 in), Z travel 1,000 mm (39.4 in), and an effective distance between columns of 2,150 mm (84.6 in).
03
No. The HPF-15M is a general crossrail-fixed machining center with a table 3,000 or 4,000 mm long. The HPF-15 has an 8,000 mm (315.0 in) long table, 2,000 mm (78.7 in) under the spindle and a crankshaft-specific purpose.
