How much does the HNK HFM 20X50 cost?
Price estimate
We do not have a price for the HNK HFM 20X50 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
Five metres of table at two metres wide: the HNK HFM 20X50 is the middle of the three large HFM 5-axis machines, measuring 2,000 x 5,000 mm (78.7 x 196.9 in) with 5,700 mm (224.4 in) of X travel.
Nothing about the head changes with length. The spindle runs at 30,000 rpm on an HSK63-A nose, the A-axis tilts ±120˚ and the C-axis rotates ±200˚. Y is 2,100 mm (82.7 in), Z is 700 mm (27.6 in) and there is 650 mm (25.6 in) between table surface and spindle nose.
So the decision is one of part mix. If most work is under four metres, the HFM 20X40 does the same job on a shorter bed. If one part family runs past five metres, only the HFM 20X60 with its 6,700 mm (263.8 in) of X will hold it. In between, a table this long also takes two shorter parts end to end, which pairs well with the pallet system HNK mentions for the series.

Frequently Asked Questions
01
5,700 mm (224.4 in), on a table 5,000 mm (196.9 in) long. The extra stroke beyond the table length is common to every HFM size and goes with the pallet system HNK describes.
02
It lists 30,000 rpm on HSK63-A, like the HFM 20X40 and HFM 20X60. The HFM 15X40 and the two narrowest sizes show 16,000 rpm first, with 30,000 rpm in braces.
03
HNK says the HFM series is designed for aircraft parts, electronic parts and automobile parts, with high speed and high precision. The 30,000 rpm spindle and 700 mm (27.6 in) Z travel point to light alloys and composites in flat or gently curved shapes.
