Price estimate

Uncertain

We do not have a price for the Hwacheon SIRIUS-1350 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-1350 is the heavy-duty version of the 2,800 x 1,250 mm (110.2 x 49.2 in) SIRIUS table: 2,550 mm (100.4 in) of X, 1,350 mm (53.1 in) of Y and 750 mm (29.5 in) of Z, with the table rated for 8,000 kg (17,637 lb). Of its SIRIUS siblings it is the one with a high-torque spindle option, and like the SIRIUS-1750 it comes in a Gap version for taller parts.

Three spindles are listed, all built-in with a BBT-50 taper. The 8,000 and 12,000 rpm units are rated 30 / 25 kW (40.2 / 33.5 hp) on a Ø100 mm (Ø3.9 in) bearing bore. The 8,000 rpm high-torque version is rated 55 / 30 kW (73.8 / 40.2 hp) and moves to a Ø120 mm (Ø4.7 in) bore, which is the one to choose for heavy roughing of steel and cast iron. Tool shanks go beyond BBT-50 here: CAT-50, SK-50 and HSK-100 are options.

The Gap version raises the spindle nose range from 250 ~ 1,000 mm (9.8 ~ 39.4 in) to 500 ~ 1,250 mm (19.7 ~ 49.2 in) and the workpiece passage from 1,550 x 800 mm (61.0 x 31.5 in) to 1,550 x 1,050 mm (61.0 x 41.3 in). The cost is height: 4,335 mm (170.7 in) against 4,085 mm (160.8 in). Z itself stays 750 mm, so on the Gap version short parts sit further from the spindle and may need a riser.

The magazine starts at 40 tools with 60 optional, memory random as standard with fixed address as an option. It takes tools up to 500 mm (19.7 in) long, the longest of the SIRIUS group, Ø120 / Ø200 mm (Ø4.7 / Ø7.9 in) with / without adjacent tools, and 20 kg (44 lb).

Rapids are 16 / 16 / 16 m/min (630 / 630 / 630 ipm). The machine weighs 25,000 kg (55,115 lb), occupies 8,120 x 4,340 mm (319.7 x 170.9 in), and needs 75 kVA and 0.5 ~ 0.7 MPa x 1,870 NL/min of air. The coolant tank is 450 L (119 US gal) and the control a Fanuc 31i-B.

Frequently Asked Questions

01 What does the SIRIUS-1350 Gap version change?

It raises the spindle nose range from 250 ~ 1,000 mm (9.8 ~ 39.4 in) to 500 ~ 1,250 mm (19.7 ~ 49.2 in) and the workpiece passage from 1,550 x 800 mm (61.0 x 31.5 in) to 1,550 x 1,050 mm (61.0 x 41.3 in). Machine height goes from 4,085 mm (160.8 in) to 4,335 mm (170.7 in). Z travel stays 750 mm (29.5 in).

02 Which SIRIUS-1350 spindle suits heavy cutting?

The 8,000 rpm high-torque version, rated 55 / 30 kW (73.8 / 40.2 hp) with a Ø120 mm (Ø4.7 in) bearing bore. The standard 8,000 rpm and the 12,000 rpm spindles are both rated 30 / 25 kW (40.2 / 33.5 hp) on a Ø100 mm (Ø3.9 in) bore, so the 12K is the choice only when speed matters more than power.

03 How does the SIRIUS-1350 compare with the SIRIUS-1250?

Same 2,800 x 1,250 mm (110.2 x 49.2 in) table, but the SIRIUS-1350 rates it for 8,000 kg (17,637 lb) against 5,000 kg (11,023 lb), adds 100 mm of Y (1,350 against 1,250 mm), and starts at 40 tools (opt.: 60) where the SIRIUS-1250 starts at 8 (opt.: 40). It also offers the high-torque spindle and the Gap version.

04 What tools fit the SIRIUS-1350 magazine?

Tools up to 500 mm (19.7 in) long and 20 kg (44 lb), Ø120 mm (Ø4.7 in) in diameter with adjacent pockets filled and Ø200 mm (Ø7.9 in) with them empty. The standard shank is BBT-50, with CAT-50, SK-50 and HSK-100 as options. Selection is memory random, with fixed address optional.
