Hwacheon MEGAII-100
3-way flat-bed horizontal CNC lathe
Mega II
Built to order. Ask for lead time.
Overview
Ø1,000 mm turning diameter, 3,000 to 10,000 mm between centers
The MEGAII-100 is the smallest of Hwacheon's Mega II flat-bed lathes, built for large shaft-type parts such as main shafts and large-diameter pipe in shipbuilding, wind power, aerospace and general industry. It runs on box ways over a 3-way bed that keeps the saddle and the built-in tailstock on separate ways. It turns Ø1,000 mm over the bed and swings Ø200 to Ø700 mm over the cross slide, with 400 mm of X travel, 3,000 to 10,000 mm between centers and an 8 ton work load. The 24 in chuck mounts on an A2-15 spindle with a Ø155 mm bore (Ø255 or Ø320 mm optional), driven at 45 / 37 kW to 750 rpm on a FANUC 0i-TF Plus.

Features
- 013-way bed with separate waysThe 3-way bed keeps the saddle and the built-in tailstock on separate ways. Hwacheon builds it in units that can be taken apart for easier connection, with a vertical chip drop that eases chip removal and fitting a chip conveyor.
- 02Rib-frame headstockHigh-precision cylindrical roller bearings carry the spindle, and a forced lubrication system circulates cooled oil to each part to limit thermal deformation.
- 03Three spindle boresA Ø155 mm bore with 941 kgf·m and 750 rpm is standard. Ø255 and Ø320 mm bores raise torque to 1,168 and 1,756 kgf·m and top out at 650 and 400 rpm.
- 04Ball screw drivesX runs on a direct ball screw. Z uses a ball screw below 8,000 mm and a ball screw or rack and pinion above 8,000 mm.
- 05Built-in tailstockThe built-in tailstock has a Ø200 mm quill (Ø250 mm on the 10000 length), an MT No.6 dead center and 260 mm of quill travel. Hydraulic and motorized tailstocks are options.
- 06Turret and control optionsA 4-position hydraulic turret and a FANUC 0i-TF Plus with Manual Guide i are standard. Options include a 12-position electric or BMT-85 turnmill turret, C-axis control, FANUC 32i-B, Siemens 828D and Sinumerik One.
