Price estimate

Uncertain

We do not have a price for the Hwacheon SIRIUS-2500/5AX 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-2500/5AX is a large-format five-axis machining center: 3,100 mm (122.0 in) of X, 2,300 mm (90.6 in) of Y and 1,000 mm (39.4 in) of Z over a 3,300 x 2,000 mm (129.9 x 78.7 in) table rated for 10,000 kgf (22,046 lb). Because the table is a fixed rectangle with nine 22 mm T-slots at 200 mm pitch, the two rotary axes have to be in the head: B swings ±100° and C turns ±210°.

The spindle is a single specification rather than a menu. It turns 15,000 rpm, is rated 18.5 / 11 kW (24.8 / 14.8 hp) and takes BBT-40 tooling, with HSK-A63 or CAT-40 as options. It runs on Ø70 mm (Ø2.8 in) bearings with grease lubrication and oil-cooler jacket cooling. That rating points the machine at contouring and finishing large surfaces with 40-taper tools, not at heavy roughing. The SIRIUS-2500, the same series without the 5AX head, uses BBT-50 spindles of 8,000 or 12,000 rpm rated 30 / 25 kW (40.2 / 33.5 hp), which is the better fit when the work is mostly heavy stock removal from one side.

Rapids are 16 m/min (630 ipm) on X, Y and Z, and B and C both rapid at 30 rpm. Spindle nose to table runs from 0 to 960 mm (0.0 to 37.8 in). The 40-tool magazine selects by memory random and takes tools up to Ø85 mm (Ø3.3 in) with neighbours, Ø170 mm (Ø6.7 in) with the adjacent pockets empty, 300 mm (11.8 in) long and 8 kgf (18 lb).

The control is a Fanuc 31i-B. Plan the site around a machine of 44,650 kgf (98,435 lb) on a 10,500 x 5,420 mm (413.4 x 213.4 in) footprint, 5,280 mm (207.9 in) high. It needs 75 kVA, air at 0.5-0.7 MPa and 1,870 NL/min, and has an 850 L coolant tank.

Strengths & Limitations

Strengths

3,100 x 2,300 x 1,000 mm (122.0 x 90.6 x 39.4 in) working envelope with five-axis head motion
3,300 x 2,000 mm (129.9 x 78.7 in) table rated 10,000 kgf (22,046 lb)
B axis ±100° and C axis ±210° in the head, so heavy parts stay still on the table
15,000 rpm spindle with BBT-40 standard and HSK-A63 or CAT-40 optional
40-tool memory random magazine taking tools up to Ø170 mm (Ø6.7 in) with adjacent pockets empty

Limitations

Spindle rating is 18.5 / 11 kW (24.8 / 14.8 hp), modest for a machine of this size
Rapids of 16 m/min (630 ipm) make long repositioning moves slow
Tools are limited to 8 kgf (18 lb) and 300 mm (11.8 in)
Needs a 10,500 x 5,420 mm (413.4 x 213.4 in) footprint and a foundation for 44,650 kgf (98,435 lb)

Best For

Large moulds and dies that need five-axis finishing Workpieces up to 3,300 x 2,000 mm and 10,000 kgf (22,046 lb) Contouring with 40-taper tools at up to 15,000 rpm Parts too heavy to tilt on a rotary table

Frequently Asked Questions

01 How does the SIRIUS-2500/5AX differ from the SIRIUS-2500?

The SIRIUS-2500 uses BBT-50 spindles of 8,000 or 12,000 rpm rated 30 / 25 kW (40.2 / 33.5 hp) and weighs 39,700 kg (87,523 lb). The SIRIUS-2500/5AX adds B and C axes in the head and uses a 15,000 rpm BBT-40 spindle rated 18.5 / 11 kW (24.8 / 14.8 hp); it weighs 44,650 kgf (98,435 lb).

02 What are the rotary axis ranges on the SIRIUS-2500/5AX?

B covers ±100° and C covers ±210°, and both rapid at 30 rpm. The linear axes rapid at 16 m/min (630 ipm), and spindle nose to table runs from 0 to 960 mm (0.0 to 37.8 in).

03 How does it compare with the SIRIUS-3000/5AX?

The SIRIUS-3000/5AX is the bigger five-axis model: a 3,500 x 3,000 mm (137.8 x 118.1 in) table rated 20,000 kgf (44,092 lb), a 24,000 rpm HSK-A63 spindle rated 69 / 45 kW (92.5 / 60.3 hp) and 90 tools. The SIRIUS-2500/5AX has a 3,300 x 2,000 mm table for 10,000 kgf (22,046 lb), a 15,000 rpm spindle and 40 tools, and it is the lighter of the two at 44,650 kgf (98,435 lb) against 63,000 kgf (138,890 lb) for the SIRIUS-3000/5AX.

04 What does the SIRIUS-2500/5AX need on site?

75 kVA of power, compressed air at 0.5-0.7 MPa with 1,870 NL/min, and an 850 L coolant tank. The machine weighs 44,650 kgf (98,435 lb), stands 5,280 mm (207.9 in) high and covers 10,500 x 5,420 mm (413.4 x 213.4 in).
