Overview
Ø1,400 mm swing over bed, 3,000 to 10,000 mm between centers
The MEGA+140 is a flat-bed horizontal CNC lathe for large shaft work such as main shafts and large-diameter pipe in shipbuilding, wind power, aerospace and general industry. It has a 2-way bed with integrated saddle and tailstock ways and a high-rigidity box-way feed system, and Hwacheon designed it to keep thermal displacement low over long runs. Swing over bed is Ø1,400 mm, distance between centers runs 3,000 to 10,000 mm, and the spindle takes a 32 inch chuck with a Ø155, Ø255 or Ø320 mm bore (Ø255 or Ø320 on the 10000). It runs on FANUC 0i-TF Plus or SIEMENS 828D.

Features
- 012-way flat bedOne bed with two ways carries the saddle and the tailstock on integrated ways. Bed width is 810 mm and bed length runs 5,670 to 12,670 mm across the seven lengths.
- 02Box-way feedHwacheon uses a high-rigidity box-way feed system for heavy cutting. X travels 730 mm, rapid traverse is 6 m/min on X and Z (5 m/min Z from the 6000 up), and cutting feed reaches 3,000 mm/min.
- 03Three spindle boresØ155 mm (A2-15, 5 to 750 rpm, No.170 metric taper), Ø255 mm (A2-15, 5 to 650 rpm, No.260) or Ø320 mm (A2-20, 5 to 400 rpm). Speed ranges shift automatically in 3 steps. The 10000 takes the Ø255 or Ø320 bore only.
- 04Built-in tailstockThe tailstock has an Ø200 mm quill, MT No.6 taper and 260 mm of quill travel. The 10000 uses an Ø250 mm quill.
- 054-way manual tool postA 4-station manual tool post takes □32 mm tools. Swing over the cross slide is Ø1,030 mm.
- 06FANUC or SIEMENSHwacheon lists FANUC 0i-TF Plus and SIEMENS 828D. The spindle motor is 45 / 37 kW with FANUC and 55.5 / 37 kW with SIEMENS.
