How much does the HNK HPM-40L (40x100) cost?
Price estimate
We do not have a price for the HNK HPM-40L (40x100) 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
At the HNK HPM-40L (40x100) the large-sized series becomes a true heavy boring and milling bridge. The spindle grows to Ø160 mm (6.3 in), the taper is ISO No.60 with 50 in braces, and speed drops to 1,000 rpm, with 1,200 rpm in braces.
A slow, large spindle is a deliberate choice. Big face mills and boring bars run at low speed and need torque and bearing size. The motor is 60/75 kW (80.5/100.6 hp), cont/30min. HNK publishes no torque figure, but the direction of the design is clear from the halved speed and the larger nose.
Ram travel doubles as well, to 2,000 mm (78.7 in), with 2,200 mm (86.6 in) in braces. Together with 2,800 mm (110.2 in) of crossrail travel and 4,000 mm (157.5 in) under the spindle, 4,500 mm (177.2 in) in braces, the machine can reach deep inside a tall housing, not just across its top.
The table is 4,000 x 10,000 mm (157.5 x 393.7 in), rated at 80,000 kg (176,367 lb). X travel is 10,250 mm (403.5 in) and Y 5,850 mm (230.3 in), between columns 4,850 mm (190.9 in) apart. The ram remains 500 x 500 mm (19.7 x 19.7 in).
