How much does the HNK HPF-15H (15x40) cost?
Price estimate
We do not have a price for the HNK HPF-15H (15x40) 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
HNK names LCD chambers first among the uses of the HPF-H series, and the HNK HPF-15H (15x40) shows why the format suits them. Its table is 1,500 x 4,000 mm (59.1 x 157.5 in), its crossrail is fixed, and the spindle turns at 6,000 rpm.
The vacuum chambers used in flat-panel display production are built from large aluminium plates and frames: wide, long, and not very tall. They need long sealing faces milled flat, many tapped holes, and pockets and ports cut at speed. None of that calls for a moving crossrail. It calls for a rigid portal at a fixed height and a quick spindle, which is exactly what this table describes.
X travel is 4,250 mm (167.3 in) and Y 3,200 mm (126.0 in). The spindle end can stand at most 1,000 mm (39.4 in) above the table, and the ram strokes 800 mm (31.5 in). Table load is 10,000 kg (22,046 lb), ample for aluminium at this size.
Spindle and drive are a Ø100 mm (3.9 in), ISO No.50 unit with 22/25 kW (29.5/33.5 hp), cont/30min. The columns are 2,200 mm (86.6 in) apart.

Frequently Asked Questions
01
HNK calls the HPF-H the optimum machining center for LCD chamber and die and mold work. Chamber parts are large and flat, so a fixed crossrail with 1,000 mm (39.4 in) of daylight is enough, and the 6,000 rpm spindle suits aluminium.
02
X is 4,250 mm (167.3 in), Y is 3,200 mm (126.0 in) and Z, on the ram, is 800 mm (31.5 in). There is no W-axis because the crossrail is fixed.
03
The HPF-20H (20x40) has the same 4,250 mm X travel on a 2,000 x 4,000 mm (78.7 x 157.5 in) table, with 2,700 mm (106.3 in) between columns and 15,000 kg (33,069 lb) of load.
04
A 22/25 kW (29.5/33.5 hp) motor, given as continuous and 30-min ratings. The spindle is Ø100 mm (3.9 in) with an ISO No.50 taper.
