Price estimate
We do not have a price for the HNK HPM-45L (45x120) 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-45L (45x120) is a heavy double column machining center with a 4,500 x 12,000 mm (177.2 x 472.4 in) table and a 120,000 kg (264,550 lb) rating.
In HNK's table it is the last model before a large jump. The next size, the HPM-50L, starts at seventeen metres of table, with a bigger ram and a 100 kW (134.1 hp) motor. Anyone whose parts run to twelve metres and well over a hundred tonnes will find this the upper limit of the mid-sized L structure: a 500 x 500 mm (19.7 x 19.7 in) ram, a Ø160 mm (6.3 in) spindle and 60/75 kW (80.5/100.6 hp), cont/30min.
What kind of part is twelve metres long, four and a half wide, and up to five metres tall? Bedplates for medium and large marine engines, complete. Frames for hydraulic presses. Housings for rolling-mill stands. The opening is 5,000 mm (196.9 in), with 5,500 mm (216.5 in) in braces, and the crossrail moves 3,100 mm (122.0 in).
X travel is 12,000 mm (472.4 in), equal to the table length. Y is 6,000 mm (236.2 in) and ram travel 2,000 mm (78.7 in), 2,200 mm (86.6 in) in braces. The spindle runs at 1,000 rpm, 1,200 rpm in braces, on ISO No.60, with 50 in braces.
