Price estimate

Uncertain

We do not have a price for the Hwacheon SIRIUS-1750 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 Hwacheon SIRIUS-1750 is the largest machine of the SIRIUS range, with 1,750 mm (68.9 in) of Y and two bed lengths: 3,000 mm (118.1 in) of X on the standard machine and 4,000 mm (157.5 in) on the L version. Z is 800 mm (31.5 in). The table is 3,200 x 1,750 mm (126.0 x 68.9 in), or 4,200 x 1,750 mm (165.4 x 68.9 in) on the L, and is rated for 10,000 kg (22,046 lb), or 15,000 kg (33,069 lb) on the L.

Where the SIRIUS-1350 offers 8,000 / 12,000 rpm, the SIRIUS-1750 is listed with 12,000 and 15,000 rpm spindles. Both are built-in BBT-50 units rated 30 / 25 kW (40.2 / 33.5 hp), with oil-jet bearings on a Ø100 mm (Ø3.9 in) bore. The higher speed range suits finishing large moulds and aluminium structures with smaller cutters, but the power rating is no higher than on the SIRIUS-850, so this is not a heavy-roughing spindle.

Part height is set by the version. The standard machine has 250 ~ 1,000 mm (9.8 ~ 39.4 in) from spindle nose to table and a 2,000 x 850 mm (78.7 x 33.5 in) workpiece passage. The Gap version moves that to 600 ~ 1,350 mm (23.6 ~ 53.1 in) and 2,000 x 1,200 mm (78.7 x 47.2 in), and the machine grows from 5,020 mm (197.6 in) to 5,370 mm (211.4 in) tall.

Rapids are 16 m/min (630 ipm) on all axes of the standard machine; the L version drops X to 10 m/min (394 ipm). The magazine holds 40 tools, 60 optional, up to 400 mm (15.7 in) long, 20 kg (44 lb) and Ø120 / Ø200 mm (Ø4.7 / Ø7.9 in) with / without adjacent tools. Eight 22 x 200 mm (0.87 x 7.87 in) T-slots cross the table.

Weight runs from 31,000 kg (68,343 lb) for the standard machine to 37,500 kg (82,673 lb) for the L version with the 60-tool magazine, and the L needs 10,740 x 5,510 mm (422.8 x 216.9 in) of floor. Power is 75 kVA, air 0.5 ~ 0.7 MPa x 1,870 NL/min, coolant 850 L (225 US gal), control Fanuc 31i-B.
