Price estimate
We do not have a price for the Hwacheon MEGA+100 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+100 is the entry size of Hwacheon's MEGA+ family of 2-way flat-bed horizontal CNC lathes. Hwacheon positions it for precision shaft-type work such as main shafts and large pipes for the shipbuilding, wind power, aerospace and general industrial sectors. It swings Ø1,080 mm over the bed and Ø720 mm over the cross slide, turns up to Ø700 mm over the cross slide, and is offered with 3,000, 4,000, 5,000 or 6,000 mm between centres, with Z travel matching the centre distance and 565 mm of X travel.
The headstock carries an 18 in chuck and is available with three spindle bores, Ø155 and Ø255 mm on an A2-15 nose or Ø320 mm on an A2-20 nose. Top speed falls as the bore grows, from 5-750 rpm with the Ø155 bore to 5-400 rpm with the Ø320 bore, through an automatic 3-step gear range. The spindle motor is rated 22 / 18.5 kW on the FANUC build and 23 / 18.5 kW on the SIEMENS build.
Tooling is a manual 4-way square tool post for □32 mm shanks, and a built-in tailstock with a Ø200 mm MT No.6 quill and 260 mm of quill travel supports long work. Hwacheon describes a high-rigidity box-way feed system on a one-piece bed, built for stable heavy cutting and low thermal drift over long cycles. Rapids are 6 m/min on both axes. Control is FANUC 0i-TF Plus, with SIEMENS 828D listed as the alternative, and the machine weighs 12,400 to 16,900 kg depending on bed length.

Strengths & Limitations
Strengths
- Three spindle bore options (Ø155, Ø255 and Ø320 mm) let buyers match the headstock to bar and pipe diameters passed through the spindle.
- Four bed lengths from 3,000 to 6,000 mm between centres cover a wide range of shaft lengths on the same Ø1,080 mm swing.
- Box-way feed system on a one-piece bed is Hwacheon's stated basis for stable heavy cutting and low thermal drift on long cycles.
- Built-in tailstock with a Ø200 mm MT No.6 quill and 260 mm quill travel supports long, heavy shafts.
- Choice of FANUC 0i-TF Plus or SIEMENS 828D control, with power ratings listed for each.
Limitations
- The manual 4-way tool post takes only four tools, so complex parts need more manual tool changes than a turret lathe.
- Maximum spindle speed is 750 rpm with the smallest bore and 400 rpm with the Ø320 mm bore, which limits small-diameter finishing.
- Rapid traverse of 6 m/min (5 m/min Z on the 6000 bed) is slow by turning-centre standards.
- Needs a large footprint: up to 9,640 x 3,050 mm and 16,900 kg on the longest bed.
