How much does the HNK HPM-20M (20x40) cost?
Price estimate
We do not have a price for the HNK HPM-20M (20x40) 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
On the HNK HPM-20M (20x40) the crossrail travel grows to 1,500 mm (59.1 in), half as much again as on the HPM-15M. The table is 2,000 x 4,000 mm (78.7 x 157.5 in) and carries 20,000 kg (44,092 lb).
Crossrail travel is the figure that tells you how tall a part a five-face machine can work around. To mill a side face, the tool has to get down beside the part; to mill the top, the rail has to clear it. With 1,500 mm of W and 800 mm (31.5 in) of ram, this size handles gearbox housings, press frames and pump casings of real height. By comparison the die and mold HPM-20H (20x40) has 1,200 mm (47.2 in) of W on the same table.
The columns are 2,700 mm (106.3 in) apart and Y travel is 3,700 mm (145.7 in). X is 4,250 mm (167.3 in), a little more than the table length. Fanuc 31i-B and Siemens 840D are the listed controls.
HNK lists a Ø130 mm (5.1 in) spindle with ISO No.50 taper in a 380 x 380 mm (15.0 x 15.0 in) ram, and motor ratings of 22/26, 30/37 and 37/45 kW (49.6/60.3 hp), cont/30min. No clean speed figure is published for the series.

Frequently Asked Questions
01
1,500 mm (59.1 in) on the W-axis, in addition to 800 mm (31.5 in) of ram travel in Z. The HPM-15M has 1,000 mm (39.4 in) of W and the HPM-25M 2,000 mm (78.7 in).
02
20,000 kg (44,092 lb). The row is starred in HNK's table, so it can be changed to the customer's requirements. The table measures 2,000 x 4,000 mm (78.7 x 157.5 in).
03
Yes, on paper. The HPM-20H lists a Ø100 mm (3.9 in) spindle, 22/25 kW (29.5/33.5 hp) and 15,000 kg (33,069 lb). The HPM-20M lists Ø130 mm, motors to 37/45 kW and 20,000 kg.
04
3,700 mm (145.7 in), a metre more than the 2,700 mm (106.3 in) between the columns. The extra stroke lets the head move outside the table edges, which a side-facing attachment needs.
