How much does the HNK HPM-25M (25x50) cost?
Price estimate
We do not have a price for the HNK HPM-25M (25x50) 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
Table load takes its biggest proportional step at the HNK HPM-25M (25x50): 30,000 kg (66,138 lb), which is 50% more than the HPM-20M. The table is 2,500 x 5,000 mm (98.4 x 196.9 in).
Crossrail travel also rises, to 2,000 mm (78.7 in). Put together, a thirty-tonne rating and two metres of rail movement describe a machine for tall, dense parts: turbine casing halves, large valve bodies, mill stands, crusher frames. HNK's own wording for the series is precision and heavy-duty machining of a wide range of workpieces.
The head is still the smaller of the two in the series. Its ram is 380 x 380 mm (15.0 x 15.0 in) with 800 mm (31.5 in) of travel, the same as on the HPM-15M. Reaching deep beside a tall part therefore depends on the crossrail coming down, not on ram extension.
X travel is 5,250 mm (206.7 in) and Y 4,200 mm (165.4 in), with 3,200 mm (126.0 in) between columns. The spindle is Ø130 mm (5.1 in), ISO No.50, with listed motors of 22/26, 30/37 and 37/45 kW (49.6/60.3 hp), cont/30min.

Frequently Asked Questions
01
30,000 kg (66,138 lb) on a 2,500 x 5,000 mm (98.4 x 196.9 in) table. That compares with 20,000 kg (44,092 lb) on the HPM-20M and 40,000 kg (88,183 lb) on the HPM-30M.
02
2,000 mm (78.7 in). The crossrail moves on the columns to set the working height, and the ram then provides 800 mm (31.5 in) of Z stroke for the cut.
03
Yes: the HPM-25H (25x50) lists a Ø100 mm (3.9 in) spindle at 6,000 rpm, 1,200 mm (47.2 in) of W and 20,000 kg (44,092 lb) of load. The HPM-25M trades spindle speed for mass and height.
04
X is 5,250 mm (206.7 in) and Y is 4,200 mm (165.4 in). The effective distance between columns is 3,200 mm (126.0 in), a starred row that HNK will alter on request.
