Price estimate
We do not have a price for the Hwacheon MEGA-R100 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-R100 is a heavy-duty flat-bed lathe built around load and torque. It swings Ø1,600 mm (Ø63.0 in) over the bed and Ø1,000 mm (Ø39.4 in) over the saddle, carries workpieces up to 15,000 kg (33,069 lb), and drives them with a 114 / 71 kW (152.9 / 95.2 hp) motor producing 3,172.5 kgf·m (31,112 Nm) through a three-step automatic gearbox. Spindle speed runs from 1 to 500 rpm.
The bed is 1,520 mm (59.8 in) wide with four ways, where the MEGA+ lathes use a single bed with two ways. Centre distances are 3,000, 4,000, 5,000, 6,000, 8,000 or 10,000 mm (118.1 to 393.7 in), with Z travel to match and 660 mm (26.0 in) of X. Both axes rapid at 6,000 mm/min (236 ipm).
Tooling reflects the cutting loads. The standard electric 4-way square tool post is □340 mm and takes □40 mm shanks with Ø60 mm boring bars, or □50 mm shanks as an option. An electric 8-position tool post is also offered, doubling the number of tools in the cut without a manual change. The built-in tailstock has a Ø230 mm (Ø9.1 in) quill with 300 mm (11.8 in) of travel and a Ø82.5 x 60° fixed centre.
The spindle is an A2-15 nose with a Ø155 mm (Ø6.1 in) bore, or Ø255 mm (Ø10.0 in) as an option. The control is a SIEMENS 828D. The site needs a 150 kVA supply at 380 V, 60 Hz, and the coolant tank holds 950 L (251 US gal). Floor area runs from 8,725 x 3,325 mm (343.5 x 130.9 in) on the shortest bed to 15,725 mm (619.1 in) long on the longest, with a height of 3,170 mm (124.8 in). The table gives no machine weight, so ask for it before planning the foundation.
