How much does the HNK HPM-50L (50x170) cost?
Price estimate
We do not have a price for the HNK HPM-50L (50x170) 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 HPM-50L (50x170) belongs to the very large end of machine building: a 5,000 x 17,000 mm (196.9 x 669.3 in) table, 170,000 kg (374,780 lb) of load and a 100 kW (134.1 hp) spindle motor.
Three things change together at this size. The ram goes to 600 x 600 mm (23.6 x 23.6 in). The spindle goes to Ø190 mm (7.5 in). And the motor row, which on smaller L models gives a continuous and a 30-min figure, shows a single 100 kW. The spindle still turns at 1,000 rpm, 1,200 rpm in braces, on ISO No.60, with 50 in braces.
The frame is correspondingly tall. HNK lists 6,200 mm (244.1 in) from table to spindle end, with no second figure in braces this time, and 4,000 mm (157.5 in) of crossrail travel. Ram travel is 2,200 mm (86.6 in), with 2,500 mm (98.4 in) in braces.
X travel is 17,000 mm (669.3 in), Y 6,600 mm (259.8 in), and the columns are 5,600 mm (220.5 in) apart. Work of this scale is the crankcase and bedplate of the largest marine diesels, the frames of big presses and the housings of heavy plate mills. HNK names ship engines, power generators and steel mill facilities.
