How much does the HNK HPF-20M (20x60) cost?
Price estimate
We do not have a price for the HNK HPF-20M (20x60) 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
Six metres of table on a fixed-rail multi-purpose bridge: the HNK HPF-20M (20x60) measures 2,000 x 6,000 mm (78.7 x 236.2 in) and travels 6,250 mm (246.1 in) in X.
A table three times longer than wide is often run as two stations. One part is machined at the far end while the operator unloads and reloads the near end, then the roles swap. HNK does not describe a pendulum mode for this model, so guarding and control provisions for it would need to be agreed, but the geometry suits it and the 20,000 kg (44,092 lb) rating is generous for two mid-size parts.
Used as one long machine instead, it takes press side frames, bed sections and structural beams. The spindle is the M-series unit, Ø130 mm (5.1 in) with ISO No.50 taper at 3,000 rpm, on 30/37 kW (40.2/49.6 hp), cont/30min, with 37/45 kW (49.6/60.3 hp) in braces.
Y travel is 3,700 mm (145.7 in) and the columns stand 2,700 mm (106.3 in) apart. Vertical range is 800 mm (31.5 in) of ram travel, 1,000 mm (39.4 in) in braces, beneath a maximum daylight of 1,200 mm (47.2 in).

Frequently Asked Questions
01
6,250 mm (246.1 in), over a 6,000 mm (236.2 in) table. Y travel is 3,700 mm (145.7 in), and the ram travels 800 mm (31.5 in), with 1,000 mm (39.4 in) in braces.
02
20,000 kg (44,092 lb), the same rating as the four-metre HPF-20M (20x40). The HPF-25M sizes carry 30,000 kg (66,138 lb).
03
The HPF-20H runs at 6,000 rpm with a Ø100 mm (3.9 in) spindle and 22/25 kW (29.5/33.5 hp), and carries 15,000 kg (33,069 lb). The HPF-20M runs at 3,000 rpm with Ø130 mm and 30/37 kW, and carries 20,000 kg.
04
