How much does the HNK HPM-40L (40x120) cost?
Price estimate
We do not have a price for the HNK HPM-40L (40x120) 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-40L (40x120) has a table of 4,000 x 12,000 mm (157.5 x 472.4 in), and its X travel is 12,000 mm (472.4 in) as well. That equality is new at this size.
On every shorter HPM model the X stroke is a little longer than the table. From twelve metres up, HNK lists the two as the same figure. The practical effect is that the spindle centreline reaches the table ends but not beyond them, so a part that fills the table cannot have its end faces milled by an attachment working past the end. Plan the set-up with that in mind, or ask whether more stroke can be supplied.
In all other respects this is the HPM-40L (40x100) with two more metres. Table load is 80,000 kg (176,367 lb). Columns stand 4,850 mm (190.9 in) apart with 5,850 mm (230.3 in) of Y. The ram, 500 x 500 mm (19.7 x 19.7 in), travels 2,000 mm (78.7 in), with 2,200 mm (86.6 in) in braces, and the crossrail 2,800 mm (110.2 in).
Up to 4,000 mm (157.5 in) separates table and spindle end, 4,500 mm (177.2 in) in braces. The Ø160 mm (6.3 in) spindle turns at 1,000 rpm, 1,200 rpm in braces, on 60/75 kW (80.5/100.6 hp), cont/30min. The taper is ISO No.60, with 50 in braces.
