How much does the Hwacheon MEGA-72 cost?

Price estimate

Uncertain

We do not have a price for the Hwacheon MEGA-72 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 MEGA-72 is a compact flat-bed lathe from the MEGA family: a Ø720 mm (Ø28.3 in) swing, 2,000 or 3,000 mm (78.7 or 118.1 in) between centres, a 14 in chuck and an 18.5 / 15 kW (24.8 / 20.1 hp) spindle running from 5 to 1,500 rpm. Over the saddle the turning diameter is Ø470 mm (Ø18.5 in), so the full Ø720 mm (Ø28.3 in) is only for work that clears the carriage.

It is a CNC lathe in the manner of a manual engine lathe. Tools sit in a manual 4-way square tool post with four faces, taking □32 mm shanks, and the spindle has a manual two-step gear range. That suits one-off and repair work where an operator stays at the machine. It does not suit unattended production, because tool changes beyond four tools are done by hand.

The headstock has an A2-8 nose and a Ø90 mm (Ø3.5 in) bore. Load ratings depend on support: 1,100 kg (2,425 lb) between centres with the tailstock and 300 kg (661 lb) in the chuck alone, a gap worth keeping in mind for long, heavy shafts. The tailstock quill is Ø90 mm (Ø3.5 in) with an MT No.5 taper. X travel is 380 mm (15.0 in), Z travel 1,900 mm (74.8 in) on the 2000 bed and 2,900 mm (114.2 in) on the 3000, and both axes rapid at 6,000 mm/min (236 ipm) on a 510 mm (20.1 in) wide bed.

The standard control is a SIEMENS 828D, with a FANUC 0i-TF Plus as an option; the supply is 38 kVA at 380 V, 60 Hz, or 220 V, 60 Hz for the FANUC version. The machine weighs 4,810 kg (10,604 lb) on the 2000 bed and 5,500 kg (12,125 lb) on the 3000, with a floor area of 4,250 x 1,930 mm (167.3 x 76.0 in) or 5,250 x 1,930 mm (206.7 x 76.0 in) and a height of 1,970 mm (77.6 in).

Frequently Asked Questions

01 Does the MEGA-72 have a turret?

No. It uses a manual 4-way square tool post with four tool faces taking □32 mm shanks. That keeps the machine simple for one-off work, but a part needing more than four tools needs a tool change by hand during the cycle.

02 What bed lengths are available?

Two: the MEGA-72 2000 with 2,000 mm (78.7 in) between centres and 1,900 mm (74.8 in) of Z travel, and the MEGA-72 3000 with 3,000 mm (118.1 in) and 2,900 mm (114.2 in). Bed length is 3,652 mm (143.8 in) or 4,652 mm (183.1 in).

03 How heavy a part can it turn?

1,100 kg (2,425 lb) with the tailstock supporting the work, and 300 kg (661 lb) held in the 14 in chuck alone. Long or heavy parts therefore need a centre in the Ø90 mm (Ø3.5 in) MT No.5 quill.

04 How does the MEGA-72 compare with the MEGA+100?

The MEGA+100 is a size up: Ø1,080 mm (Ø42.52 in) over the bed against Ø720 mm (Ø28.3 in), an 18 in chuck against 14 in, and bore options of Ø155, Ø255 or Ø320 mm. The MEGA+100 tops out at 750 rpm, half the 1,500 rpm of the MEGA-72.

05 Which control and power supply does it use?

A SIEMENS 828D as standard, on 380 V, 60 Hz. With the optional FANUC 0i-TF Plus the supply is 220 V, 60 Hz. Either way the machine needs 38 kVA, and the coolant tank holds 180 L (48 US gal).
